CHAPTER 2


2 Cable Tray Design – Basic Concepts

There is a separate design hierarchy for cable tray routing which follows the same principles as for pipe routing; each cable element may own a number of branches. In turn, branches may own a number of cabling components like bends, risers and reducers. The difference between cable tray and branches is that a branch is only considered to have two ends, while a cable tray may have any number of ends, depending on the number of branches it owns.

The diagram below shows a cable tray with three ends and two branches. The second branch is connected to the first at the tee. Although a branch only has two ends, it may own components (in this case a tee), which connects to other branches. These simple concepts enable any number of cable tray configurations to be developed, and form the basis of all the AVEVA Marine cable trays encountered.

2.1 Starting an Outfitting Session

To start the AVEVA Marine application, select All Programs > AVEVA Marine> Design > Marine 12.1 > Outfitting The AVEVA Marine - Outfitting Login form appears, enter the following data:

Project Training Username ELECT Password ELECT MDB ELECTRICALFWD,

Then click the Login button. Setting the project to Training on the AVEVA Marine – Outfitting Login form will result in the use of the Marine Training Project; this will be referred to as MTP for the remainder of this guide. A default screen layout will be displayed comprising the application pull-down menu and a Design Explorer showing all the objects from the current project database. The user can reposition and, in some cases, resize the Outfitting windows.

Once the Outfitting module has been started, the user must check that the Cable Trays application is running. This can be seen on the top of the design framework. If it does not show Cable Trays, select Design > Cable Trays… from the application pull-down menu to change to the correct application.

2.2 Cable Tray Specifications

In the same way that design offices have standard cable tray specifications for different materials, AVEVA Marine has a set of specifications from which the user can choose. In fact all components used must be defined in the Catalogue and placed in a Specification before the designer can select them. In the Training project there are three main such specifications:

SCTG STANDARD DUTY CABLE TRAY

MDCLG MEDIUM DUTY CABLE TRAY

HDCTG HEAVY DUTY CABLE TRAY

These specifications contain all fittings required for the course exercises.


11

www.aveva.com


2.3 Setting the Appropriate Specification

The first task when building a cable tray is to decide which specification to use. Having decided on the appropriate specification, it is then set as an attribute of the cable tray. Any subsequent branches will automatically be assigned with the same specification (although this can be re-specified if required). On entry to the Cable Tray Application the Default Specifications Form is displayed.

To change the default specification, select Settings > Default Specification, and select the new specification

Select SCTG from the list and click OK

To change the Main or Branch specification, select Modify > Main or Modify > Branch > Specification from the pull down menu and select the new specification required

The Cable Tray Toolbar is used to view and manipulate the cable tray specification. Clicking on the Set Default Cable Tray Specification icon to the left displays the Default Specification form. The text box adjacent to the specification icon displays the default cable tray specification.

2.4 Cable Tray Branches

Branches serve two purposes:

They define the start and finish points of a cable tray route (known as the Head and Tail in AVEVA Marine).

They own the cable tray components, which define the route.

The position and order of the cable tray components below branch level determine the physical route. In AVEVA Marine, it is only necessary to consider the fittings, because the cable tray that appears between fittings is automatically selected according to the specifications of the fittings.


12

www.aveva.com


2.5 Cable Tray Branch Heads and Tails

All branches need to have a start and end point. These can be a position in space (3D co-ordinates), the flange face of an equipment nozzle or pipe, a tee or various other points in the design. Heads and tails are set up via a series of attributes that belong to the branch element. The attributes for heads of branches are:

HPOS The position in the zone where the branch starts. HCON The connection type of the branch end (BOXI or OPEN). HDIR The direction in which the start of the branch is pointing (as if the user looks down

the tray / ladder). HBOR The width of the cable tray. HREF The name of the item to which the branch head is connected (i.e. Href TEE 1 of

BRANCH /CTRAY_YY2/B1). If this is not set, then the branch is open. HSTU This is a reference to the catalogue, which determines the material of the first piece

of cable tray, between the start of the branch and the first fitting (this still needs to be set, even if there is a fitting connected directly to the head).

The attributes for tails of branches are:

TPOS The position in the zone where the branch ends. TCON The connection type of the branch end (BOXI or OPEN). TDIR The direction in which the end of the branch is pointing (as if the user looks back

down the tray / ladder). TBOR The width of the cable tray. TREF The name of the item to which the branch tail is connected (i.e. Tref TEE 1 of

BRANCH /CTRAY_YY2/B1). If this is not set, then the branch is open. It is not necessary to specify each of these attributes every time a branch is created. On most occasions the attributes for the head or tail are set automatically (i.e. where a branch is connected to a tee).

2.6 Cable Tray Creation

To display the Create Cable Tray Main form the user must select Create > Main from the main pull down menu at an appropriate hierarchical level, i.e. a ZONE. The Create Cable Tray Main form is now displayed. The user can enter a name for the cable tray and select a specification that will be applied. Clicking the OK button will create the administrative elements for the cable tray in the design hierarchy. It will also switch to the Create Cable Tray Branch form afterwards. The Create Cable Tray Branch form is auto populated with a branch name and specification inherited from the owning cable tray. Selecting the OK button will create a new branch in the cable tray and automatically open the Branch at Explicit Position form.

2.7 Cable Tray Branch Head / Tail Positioning Explicitly

A new branch must have two ends (its Head and its Tail) positioned in the design model. When a branch is created, the Branch at Explicit Position form is displayed. This form is used to position and orientate the branch head and tail explicitly and define the connection type for each. The Branch at Explicit Position form may also be shown by selecting Modify > Branch > Explicit The form can be used to:

Set the Head / Tail option button to show the end of the branch desired to position and orientate.

Define the Position by entering the required coordinates in the X, Y and Z text boxes, using the option buttons to set the appropriate direction in each case.

Use the Width option button to change the tray width at the Head / Tail if required.

Enter the Direction in which the head / tail is to be orientated.

Use the Connection option button to select how the tray is to be terminated at the Head / Tail. The options are Open where the end will be left open for connection to another tray length (in another branch) or Boxing where the end will be closed to terminate the tray length.

Change the Head / Tail option and repeat for the other end of the current branch if required.


14

www.aveva.com


If the Branch at Explicit Position form is used to change the width of an existing branch, all components owned by the branch must be reselected so that they are compatible with the new width. To do so, navigate to the branch and select Modify > Branch > Reselect. A Reselect Branch form will be displayed. On clicking Apply, all branch components will be reselected automatically in the hierarchical order. Depending on the current Choose options for the cable tray, it may be necessary to choose from the available types for some components. (Note that the Choose form applies to the component next to the one highlighted in the Design Explorer, not to the current element)

Selecting components with different sizes in a preconfigured pipeline or cable tray network can lead to incorrect geometry. Check the effects by studying the 3D View and, if necessary, by running a Data Consistency Check

2.8 Cable Tray Branch Components (Fittings)

On initial definition of a branch head and tail, the branch will consist of one piece of cable tray running in a straight line between the head and tail positions. This will appear as a dotted line between the two points unless the head and tail are aligned along a common axis. (The dotted line indicates that the branch route is geometrically incorrect.) The next step in designing a cable tray is to create and position a series of fittings, which define the cable tray route required. It is necessary to decide which cable tray components are needed in order to satisfy the requirements of the process and the design needs. It is not necessary to know specific fitting dimensions, as AVEVA Marine derives these automatically from the catalogue. To create cable tray fittings the user must select an item from the list of fittings available from the associated cable tray specification. The main types of fitting available are Bends, Elbows (Risers), Tees, Reducers, Crosses, and Fixed Tray (FTUB). For all cable tray components the user must:

Select the component from the cable tray specification.

Position the component and set the orientation.

Head

Tail


15

www.aveva.com


2.8.1 Creating Branch Components (Cable Tray Fittings)

The user can create cable tray fittings by selecting Create > Components from the main pull down menu. The Cable Tray Component form shows all the component types that are available in the current cable tray specification. It is possible to select components from an alternative specification by reselecting from the Cable Tray options pull-down list.

Normally Branch Members are defined in Forwards mode, that is, one after the other, starting at the Head. Sometimes it is more convenient to build the branch from the Tail first, in which case, Backwards mode is more appropriate. If the Auto Conn check box is checked, this will ensure that components are automatically connected to the previous component (or to the Branch Head if it is the first component). Components are created by selecting the required fitting from the scrollable list and then clicking the Create button. The CHOOSE form displays all available components for the specification selected.

After selecting the initial component from the CHOOSE form and clicking OK button, the Open Tray Direction form will open. The user must set the

tray direction by entering a valid direction in the text box then click the OK

button.

2.8.2 Selecting the Component from the Specification

On selection of a component from the catalogue, there are often a number of choices available. The description of the component item can be presented in one of three ways.

Basic the least amount of information is displayed. Text description and material displayed. All all available data is shown.


16

www.aveva.com


The manner in which component information is displayed is changed by selecting Settings > Choose Options. This will display the Choose Options form. This selection criteria setting will determine the amount of information displayed. Auto Connect can also be set from this form. Below shown the effects of Selection Criteria options on the CHOOSE form.

Basic

All

Text

2.8.3 Branch Component List Order

With equipment and structures, the order in which items are created is of no importance to the final design. With cable tray components, the order in which they are laid out, as well as their individual positions and orientations, determines the final cable tray route. Below is a Design Explorer window showing the components of a typical cable tray. The current element is highlighted.


17

www.aveva.com


Any new item in the branch appears after the current element on clicking Create button. The new item then becomes the current element. The only slight deviation from this is for a new branch, in which case the new item will be the first item in the branch. Hierarchical order will become second nature after the creation of a number of branches, but for the time being remain aware of it and consider carefully where the next item is going to be inserted.

2.8.4 Automatic Positioning and Orientation of New Components

On selection of a component, in many cases, it is not necessary to go through the stages of positioning and orientation. This is because the component is automatically connected to the previous one.

2.8.5 Positioning and Setting the Orientation of Components

Having created and chosen a component, the next stage is to position it. If it is the first component in the Branch the Open Tray Direction must be specified. Components can be positioned using the Distance button on the Cable Tray Components form. After the component is created, entering a value in the Distance textbox and clicking the Distance button will move the component that distance from the previous component.

Components can also be moved by using any selection from the Modify, Position or Orientate options from the Cable Tray Application menu. Components can also be positioned and orientated using the Model Editor.


18

2.8.6 Arrive and Leave Points

Cable tray components have P–points (similar to those for equipment primitives). The significance of P–points is two–fold. First, they define the connection points, and second, they determine the branch flow through the component by means of Arrive and Leave attributes. For the reducer shown below, the large end is at P1 and the small end is at P2. If this component is used to increase the width of the branch, the flow in the direction of the branch will be from P2 to P1. In order to specify in the flow direction in AVEVA Marine, set the two numeric attributes, Arrive and Leave, to the P–point numbers required. In this case, Arrive would be set to 2 and Leave would be set to 1 (By default, Arrive is 1 and Leave is 2). Reducer Bends Tees Elbows or Risers

Exercise 1 - Create a Cable Tray

1. Prior to creating a cable tray the correct hierarchy must be present in the design explorer. Navigate

to the WORLD level then create a new SITE named CABLE. Under the SITE CABLE create a new ZONE named 101C-CABLEWAYS

2. Create the Cable Tray Main CTRAY_YY010 and set the specification to SCTG.

3. Create the Branch CTRAY_YY010/B1.

4. Position the Branch Head, X 2500, Y 2000, Z 14500 and the Tail -X 3000, Y 2000, Z 13250.

5. Set the width as 600mm for the Head and 450mm for the Tail and the direction to -X for the Head

and X for the Tail.

6. Set the connection to Open for both Head and Tail.

7. Create two Riser components by working forward from the Head position. Ensure the Auto Connect check box is selected then add a 90 degree Outer Riser (OR) to the head of the branch. Set the tray direction to Z. Add a 90 degree Inner Riser (IR) to the previous elbow. Set the graphical view to ISO4. The branch should look like this:

CHAPTER 3


3 Connecting and Positioning Cable Tray Components

A Connect command both Orientates and Positions the current component so that its P-arrive is directed towards, and is aligned with, the P-leave of the previous component (in forwards mode). Unless overridden, Connect function also checks that the components to be connected have compatible connection types (as defined by the Connection Compatibility Tables in the Catalogue database). Before starting the worked examples covered in this chapter, some Cabletray elements need to be added to

the 3D view. These elements are created by the input file ‘CTRAY_YY2_DATAL.txt’ added below the

World. This will automatically add SITE CABLETRAY_TRAINING_YY2 to the design Explorer, and CTRAY_YY2 to the 3D view. Save work.

3.1 Connecting the Branch Head or Tail

A variety of branch connection options are available to the user. Users can access connection options by selecting Connect > Branch from the main pull down menu.

This will open the Connect Cable Tray Branch form.

It is important that the user is located at branch level (or below) in the design hierarchy when the command is actioned. If the user is not at the correct level a warning message will be displayed as shown

The Connect Cable Tray Branch form allows the user to set the connection details of both the head and the tail of the selected branch. The user can toggle between the head or tail by making an appropriate selection from the option list in the top left corner of the form. The branch to which the connection is being applied is displayed next to the head/tail selection.

Main Branch with through Tee New Branch Connected to Tee

3.1.3 Connecting to Multi-way

On applying the Multi-way option, the user is prompted to identify the design point to connect to. As multiple P-points are potentially available to connect to, the user cannot simply select an element. An individual P-point within the multi-way element must be selected.

3.1.4 Connecting to Branch Head

On applying the Branch Head option, the user is prompted to identify the branch to connect to. A graphical selection of any valid branch can be made and any part of the branch can be selected. The application will then derive the head position of the selected branch and update the head/tail detail of the connecting branch.

3.1.5 Connecting to Branch Tail

On applying the Branch Tail option, the user is prompted to identify the branch to connect to. A graphical selection of any valid branch can be made and any part of the branch can be selected. The application will then derive the tail position of the selected branch and update the head/tail detail of the connecting branch.

3.1.6 Connect to Last Member

On applying the Last Member option, the head or tail position will dynamically update to the position of the last member in the branch, in a similar manner to Connect to First Member covered in 3.1.1

The Bend is moved along its axis to the position of TEE1. Dismiss the Cable Tray Components form.

3.5 Positioning Components

The Position Component options enable the user to move a component without specifying a direction. The direction of movement is the direction of the component. The options are as follows:

Distance Through Clearance Plane Through Plane Clearance

Moves the component by a given distance. Moves the component along a given point. Moves the component to within a given clearance of a give item or point. Moves the component along the line of the branches so that the component moves until it intersects a plane through a given point. Extends the arrive tube so that the component moves until it is within a given clearance of a plane through a given point.

3.5.1 Distance

Distance function allows the user to position a component at a given distance from a specified point. The direction of movement and the distance are along the current components arrive/leave axis. Selecting Position > Component > Distance from the main pull down menu will open the Distance form. A positional axis will also appear on the component in the graphical view.

The user must then enter the distance required. Two option lists below the distance text box control how the nominated distance will be applied. Depending on the configuration selected, cursor picks or additional data entry may be required. A CE button is provided on the form allowing several components to be positioned without closing the form.


30

www.aveva.com


Positioning options on the pull down menus are as follows:

Only Spool Only Infront / Behind Onto / Under From / To

Positions relative to the previous item. Positions component at given distance from next to achieve required tube length between them. Can be used for any direction in a plan view. Distance is measured along direction of movement, relative to a specified point Can be used for any X, Y, -X, or -Y view direction. Distance is measured along direction of movement, relative to a specified point. Can be used with any direction in an elevation view. Distance is measured along direction of movement, relative to a specified point.

The second pull down specifies the reference point from which the distance is measured. The choices are:

Cursor ID Cursor ID P-Point Coordinate Name Pin Next / Previous Head / Tail Current

A cursor-identified 3D position A cursor-identified item whose origin is at the required position. A cursor-identified P-point at the required position An explicit position whose coordinates you will enter A named item whose origin is at the required position A numbered construction pin at the required position Adjacent component in branch members list. Head or tail of owning branch. Current item (used to reposition component when previous item in branch members list has been moved).

The Apply button allows the user to action distance modification, Reset allows the user to return to the default values. The Dismiss button is used to close the form.

In this example BEND 3 of branch CTRAY_YY2/B1 will be moved 1500mm from the previous component. Make BEND 3 the CE. On the Distance form, select From and Previous from the pull-down menus. Enter a value of 1500 in the Distance text box and click Apply. The bend is moved 1500mm from the previous component (BEND 2). Dismiss the Distance form.


32

www.aveva.com


3.5.2 Through

The Through function allows the user to align a component with a specified point. The direction of movement is along the current components arrive/leave axis Selecting Position > Component > Through from the pull down menu will open the Through form.

The Through option list provides a variety of positioning options that can be applied to the branch. Like the Distance form, the Through form has a CE button allowing the user to position several components without having to close the form.

In the following example, the Tail option will be applied. Other combinations will require the user to either pick with the cursor or enter data on the resulting form, depending on the way the user chooses to specify the position as previously described. With BEND 3 the CE, select Tail from the pull-down menu and click Apply. The elbow moves along its Arrive axis and lines up with the branch Tail.

Dismiss the Through form.


33

www.aveva.com


3.5.3 Clearance

This function allows the component to be moved to a given clearance from a specified point. The direction of movement is along the current components arrive/leave axis. Selecting Position > Component > Clearance from the pull down menu opens the Distance form.

The user must then enter the clearance required. Two option lists below the clearance text box control how the nominated clearance will be applied. Depending on the configuration selected, cursor picks or additional data entry may be required. A CE button is provided on the form allowing several components to be positioned without closing the form.

In the following example, BEND 3 will be moved so it has a clearance of 200mm behind the leave Ppoint of BEND 2. With BEND 3 the CE, select Behind and ID P-Point from the pull-down menu, enter 200mm in the Clearance text box and click Apply. The user will then be prompted to ‘Identify design ppoint’. Select the leave Ppoint of BEND 2 as shown. The elbow moves along its Arrive axis to a position 200mm clear of the selected Ppoint.

Dismiss the Distance form.

When using the commands Component>Position, Component>Clearance. etc on a BEND or RISER component, note that the direction of movement is always on the Arrive axis.


34

www.aveva.com


3.5.4 Plane Through

This function allows the user to move the component until it intersects a plane through a given point. The direction of movement is along the current components arrive/leave axis. Selecting Position > Component > Plane Through from the pull down menu opens the Plane Through form.

The user must define a plane by specifying its direction (defined as the direction normal to the plane’s surface) and a point through which it passes. The user must enter the plane direction in the Plane text-box. Then the reference point through which the plane passes can be selected from the Through options list as described previously. A CE button is provided on the form allowing several components to be positioned without closing the form.

3.5.5 Plane Clearance

Plane Clearance function allows the user to move the component until it has a given clearance distance from a plane through a given point. The direction of movement is along the current components arrive/leave axis. Selecting Position > Component > Plane Clearance from the pull down menu opens the Plane Clearance form. An axis aid is displayed on the component to be moved. The user must define a plane by specifying its direction (defined as the direction normal to the plane’s surface) and a point through which it passes. The user must enter the plane direction in the Plane text-box and a clearance distance (that will be applied from the plane) in the Clearance text box. Two option lists below the clearance text box control as described previously how the clearance will be applied, relative to the plane, and the point through which the plane will pass.

CHAPTER 4


4 Branch Re-routing and Connection References

4.1 Swap Branch

The Swap Branch function allows the user to change the offline leg direction of a Tee. Before carrying out the Swap Branch command it is necessary to know the orientation of P-points at the selected component. The orientation can be checked by selecting Query > General from the main pull down menu. This will display the Query form. Using the appropriate options list the various P-points of the selected component can be checked. After establishing the orientation of the P-points the user can re-orientate the component. A Tee can be rotated through 180 degrees, so that the direction of its offline leg (P3) is reversed, by navigating to the Tee and selecting Orientate > Component > Swap Branch from the pull down menu. The component immediately updates in the graphical view. The new orientation can be confirmed by re-checking the P-point orientation using the Query > General function.

In order to retain the correct orientation for the open side of the tray, this operation results in the P-arrive (P1) and P-leave (P2) directions being reversed. To maintain connectivity, P-arrive is reset to P2 and P-leave is reset to P1 automatically

4.2 Change Exit

The Change Exit function allows the user to change the Branch Direction at a Tee or Bend. By default, P-arrive for a tee is set to P1 and P-leave is set to P2. The off-leg (for connection to another branch) is set to P3. The P-leave of a tee can be changed from P2 to P3. This is achieved by navigating to the tee then selecting Orientate > Component > Change Exit. This function allows the user to toggle the P-leave point between P2 and P3. The same function can also be applied to a Bend to change the direction of the P-leave point. It swaps the P-arrive and P-leave, so that P1 is P-leave, and P2 is P-arrive.


38

www.aveva.com


4.3 Changing Branch Routing at a Tee

By default, the P-arrive of a tee is set to P1 and the P-leave is set to P2, so that the branch route continues straight through the tee. It is possible to change the P-leave such that the branch route enters or leaves the tee via P3. This is achieved by selecting Modify > Component > Route from the pull down menu. This opens the Modify Route form.

Three radio button options are available to the user. As previously described the default setting is the Route Through option. Selecting the Branch Off option will change the P-leave point to the orthogonal branch of the tee (i.e. P3). Selecting the Split Route option will change the P-arrive point to the orthogonal branch of the tee. The P-leave point will be at P2.

Once the desired configuration has been selected the user must click the Apply button to instigate the change. The tee orientation will immediately update to suit the new configuration. The form also contains a CE button which allows the user to modify the configuration of several tee components without closing the form.


39

www.aveva.com


4.4 Changing a Component Connection Reference Explicitly

On connection of a multi-way component within a branch to another item (such as a nozzle, or the head or tail of another branch), the Connection Reference (CREF) attribute of the component identifies the connected item. To unset the component reference, or connect it to a different item, the user must select Modify > Component > Connection Ref from the pull down menu. Doing so will open the Connection Reference form. The appearance of the Connection Reference form will vary depending on the number of offline legs held by the cable tray component being modified. For a component with only one offline leg (i.e. a tee), the Connection Reference form will only display the connection reference for the offline leg (usually P3). Components with more than one off-line leg have a CRFA attribute which is used to store the connection reference at each P-point. For components with more than one offline leg (i.e. a cross), the Connection References form displays an options list and a reference text box. The connection reference for each P-point can be checked by selecting the desired point from the options list. The connection reference can be removed by clicking the Unset button adjacent to the reference text box. The connection reference can be changed to another item by entering the item name in the reference text box then clicking the Apply button. Clicking the Reset button will restore the last connection references written to the database.

Applied connection references will be written to the database when the form is applied

Changing the connection reference does not change the position or orientation of any components, so it is also necessary to ensure that the resulting geometry makes sense

Exercise 3 – Branch Routing

Using the TEE in CTRAY_YY010 created in Exercise 2, try out the different Branch Routing options, Route Through, Branch Off and Split Route.

Ensure the TEE is left with the Route Through option at the end of the exercise.

Save Work.

CHAPTER 5


5 Positioning Commands for Branch Head/Tail

Before starting the worked examples covered in this chapter, an additional branch needs to be added to the 3D view. This branch is created by the input file CTRAY_YY2_BRANCH2.DATAL added below the PIPE CTRAY_YY2 in the Design Explorer. This will automatically add the branch to the 3D view. Selecting Position > Branch from the pull down menu displays a range of positioning options available to the user. General Distance Through Move Drag

Positions the Head / Tail at a given point Moves the Head / Tail along the current branch direction until it is a given distance from a given reference point Moves the Head / Tail along the current branch direction until it is aligned through a specified point Moves the Head / Tail in a given direction by a given Distance, Through a given point, or to within a given Clearance of another item Allows you to move a constrained network in a given direction by a given Distance, Through a given point, or to within a given Clearance of another item


42

www.aveva.com


5.1 General

Selecting Position > Branch > General from the main pull down menu displays the Branch at General Position form. An axis aid is also displayed in the graphical view. The user can select whether the branch head or tail will be positioned by making the appropriate selection from the options list in the top left corner of the form.

The user can then select from a range of positioning points from the ‘At’ options list. Subject to the positioning point selected, the user will be prompted to make a graphical selection or enter further data. Once the positioning point has been established the user can position

the branch by selecting the Apply button.

The form contains a CE button allowing the user to modify several branches without closing the form. In this example, the Head position will be moved using ID P-Point. Select Position > Branch > General, set the pull-down menus at Head and ID P-Point. And click Apply. The user is prompted to ‘Identify design ppoint’. Select off-branch P3 Ppoint of TEE1 of branch CTRAY_YY2/B1 as shown. The branch head moves to the selected Ppoint.


43

www.aveva.com


5.2 Distance

Selecting Position > Branch > Distance from the main pull down menu displays the Position form. An axis aid is also displayed in the graphical view.

The user can select whether the branch head or tail will be positioned by making the appropriate selection from the options list in the top left corner of the form. A value must also be entered in the distance text box. The user must then stipulate how the distance will be applied and where it will be applied from. This is done by making selections from the two option lists below the distance text box as previously described. Once the positioning point has been established the user can position the branch by clicking the Apply button. The form contains a CE button allowing the user to modify several branches without closing the form. In this example, the Head position will be moved by a specified distance Behind an ID Ppoint. Select Position > Branch > Distance, set the pull-down menus at Head, Behind and ID P-Point. Set the Distance textbox to 500mm and click Apply. The user is prompted to ‘Identify design ppoint’. Select off-branch P3 Ppoint of TEE1 of branch CTRAY_YY2/B1 as shown. The branch head moves to a position 500mm behind the selected Ppoint.


44

www.aveva.com


5.3 Through

Selecting Position > Branch > Through from the main pull down menu displays the Position form. An axis aid is also displayed in the graphical view. The Through command allows the Head or Tail of the branch to be aligned with a specified point. The direction of movement is along the current Head/Tail direction. The user can select whether the branch head or tail will be positioned by making the appropriate selection from the options list in the top left corner of the form.

The ‘Through’ option list provides a variety of positioning options that can be applied to the branch. Once the

positioning point has been established the user can position the branch by selecting the Apply button.

The form contains a CE button allowing the user to modify several branches without closing the form. In this example, the Tail position will be moved along its axis to align with a specified Ppoint.. Select Position > Branch > Through, set the pull-down menus at Tail and ID P-Point and click Apply. The user is prompted to ‘Identify design ppoint’. Select a Ppoint on BEND1 of branch CTRAY_YY2/B1 as shown. The branch Tail aligns with the selected Ppoint, along its axis.

5.4 Alternative Positioning Forms

The following forms can be used to compliment other positioning and editing functionality covered in this guide. For the purposes of cabletray modelling there are four main forms to consider which are all available from the application pull-down menu:-

Move form - accessed using Position > Move…

Drag Move form - accessed using Position > Drag…

Move Branch form - accessed using Position > Branch > Move…

Drag Move Branch form - accessed using Position > Branch > Drag…

5.4.1 Move Form

Navigate to BRAN CTRAY_YY2/B1 and select BEND 1 to demonstrate the Move form. The Move form is used to move the current element in a given direction. This can be a specified distance in that direction, to a position relative to another element, or relative to a plane through a given component. All of the forms have four common tabs:-

Distance

Through

Clearance

Towards

5.4.1.1 Distance Tab

The Distance tab allows the user to move the current element so that its origin or nominated PPoint moves a distance in a given direction.

The Parameters section of the Move form allows the user to set the following:-

Origin – using a scrollable to select Origin, Arrive or Leave.

Distance

Direction

WRT – sets the frame of reference for the direction of movement With Respect To a specified element.

Movement Direction

Distance


46

www.aveva.com


The WRT setting can be influenced by the four buttons as explained:-

- Direction with respect to itself

- Direction with respect to owner or first ancestor that has an orientation

- Direction with respect to the World

- Direction with respect to a picked element

For very simple movements the Parameters section of the form can be employed on its own with the Target section using the Relative To setting of No Target, for example:-

Before

After

However the Target section of the form provides additional functionality:-

Relative To - allows the user to select from numerous options to determine how the element is positioned in relation to the target element or position.

In Front / Behind

On Top / Under From / Towards

DistanceUnder

DistanceOn Top

MovementDirection

Distance To

MovementDirection

Distance From


47

www.aveva.com


With the Relative To option set to something other than No Target, the Select options become available to the user. The setting of this option determines how the remainder of this form will function as shown:-

Selecting the Element option allows the user to specify the element to be referenced either by keying in the name or by clicking the Pick Target Element button and indicating the element in the 3D View.

Alternatively, selecting the Position option forces the users to click the Pick Target Position button. This allows the user to use the Positioning Control toolbar to perform an EDG pick to specify the position in the 3D View.

The resulting position is indicated in the 3D View as an aid as shown. In this case the Ppoint on the straight cabletray element has has been used, however the used can pick Ppoints on hull or other outfitting elements.

The remaining options of Next, Tail, Previous, Head and Current require no additional input.

Checking the Plane Through Target check box allows the user to specify the direction of the Plane. The current element is moved so that its origin moves a given distance in a given direction, where the distance is measure from intersection of direction of movement and the reference plane. The reference plane is specified relative to the element or position nominated in the Select scrollable list.


48

www.aveva.com


Movement Direction

Plane Through

5.4.1.2 Through Tab

The Through tab allows the user to move the element in a given direction until it reaches a point or is relative to a plane perpendicular to the direction of movement through another point.

The Parameters section of the form is identical to that detailed for the Move tab with the exception that there is no Distance input text box. Unlike the Move tab the Target section must be used to perform an operation. The Target section of the form is similar to that detailed for the Move tab. However there is no Relative To scrollable list and the Through scrollable list is the same as the Select version on the Move tab.

Checking the Plane Through Tangent check box allows the user to specify the direction of the Plane. The current element is moved so that its origin moves to the intersection of the direction of movement and the reference plane. The reference plane is specified relative to the element or position nominated in the Through scrollable list.

www.aveva.com


ClearanceBehind

MovementDirection

Clearance In Front

5.4.1.3 Clearance Tab

The Clearance tab allows the user to move the element in a given direction so that its obstruction volume or a Ppoint is a given clearance from another element. The clearance is measured in the same direction as the movement.

The Parameters section of the Clearance tab differs slightly in that the Origin also contains an All option which allows for any obstruction volumes. The user can also specify the amount of Clearance required. The remainder of this form works in the same fashion as the Move tab. The illustration below shows how the Clearance tab can be used in conjunction with the Relative To options to great effect.

51

www.aveva.com


5.4.2 Move Branch Form

The Move Branch form is identical to the Move form with the exception of the Origin option in the Parameters section of the form. The only options available are Head and Tail. As implied the form is only used to reposition the head or tail of the branch using the same methods as previously covered on the Move form.

5.4.3 Drag Move and Drag Move Branch Forms

The Drag Move and Branch Drag Move forms are identical to the Move and Move Branch forms except that it applies the Drag rules to a constrained network. In the previous examples the positioning commands do not move the connected elements. The construction of the constrained network depends on the direction of the drag operation and the type of item to be dragged.

Refer to the Dragging Equipment and Piping Networks section of the Design Reference Manual for information relating to the boundaries of a constrained network.


52

5.5 Quick Cable Tray Routing using the Model Editor

The Model editor allows the user to select and drag components along a specified direction and to rotate components around their origin point. The editor uses three handles: Extend Route Handle This is used to extend the route in the direction indicated by the handle. Cardinal Direction Handles These are used to move components in a cardinal direction Rotational Handles These are used to rotate components about their origin.

For cable tray components the model editor should only be used to move components within the route direction

The quick cable tray routing handle is used to define a routing vector within the constraints of the currently selected badly defined route. A badly defined route is defined in general terms as where either, there is a bad alignment between two components, the head or tail of a branch is incomplete, i.e. where the Head / Tail attributes are left in their default state, the Head / Tail is positioned but not connected and the Head / Tail connection type is unset. This usually equates to the dotted line representation of implied ftube, where implied ftube cannot be drawn. An exception to the above could be where a cable tray Branch does not have specification reference set. The handle can be dragged by using either the LHS (left hand side) or RHS (right hand side) mouse buttons. By default the handle will move in multiples of the currently defined linear increments. If the RHS mouse button is clicked when the cursor is over the cable tray routing handle, the user will be presented with a context sensitive menu. The menu will display the available options which relate to the drag.

CHAPTER 6


6 Fixed Length Trays and Implied Straights

Implied straights in cable trays can be compared with implied tubing for piping. Implied straights occur where there is a physical distance between consecutive list order components. Implied straights can be replaced by fixed length tray (FTUB) elements.

6.1 Replacing Implied Straights with Fixed-Length Trays

Fixed-length tray (FTUB) elements can be applied to all or part of the current branch in the model. Creating fixed length trays will replace sections of implied straights.

To create fixed length trays the user must be at branch level or below in the design hierarchy. Selecting Modify > Fill from the pull down menu will open the Fill Cable Tray Branch form.

The Fill options list allows the user to select the extent of the cable tray branch that fixed length trays will be applied to. Four options are available to the user:

Branch Replaces all implied straights with fixed length trays for the entire branch. Components Inserts fixed length trays between two specified components. Head to Component Inserts fixed length trays between the branch head and a specified

component. Component to Tail Inserts fixed length trays between a specified component and the branch

tail.

Model with Implied Straights Model with Fixed Trays Applied to Branch

The fixed-length trays used are derived from the current branch specification. The number of trays used in each location is calculated from the length of the implied straight which they replace.

6.2 Replacing Fixed-Length Trays with Implied Straights

In design, it may be necessary to remove fixed-length tray (FTUB) elements from all or part of the current branch in the model. To remove fixed length trays the user must be at branch level or below in the design hierarchy. Selecting Modify > Unfill from the pull down menu will open the Unfill Cable Tray Branch form. The Unfill options list allows the user to select the extent of the cable tray branch that fixed length trays will be removed from. Four options are available to the user:

Branch Removes all fixed length trays and replaces them with implied straights along the entire branch.

Components Removes fixed length trays between two specified components and replaces them with implied straights.

Head to Component Removes fixed length trays between the branch head and a specified component and replaces them with implied straights.

Component to Tail Removes fixed length trays between a specified component and the branch tail and replaces them with implied straights.

CHAPTER 8


8 Data Consistency Checker

The Data Consistency checker is predominantly for Pipes and Structure but can also be applied to the Cable Tray Design application.

8.1 Possible Types of Data Error

The data consistency checking utility, available within Design’s Piping, Structural and Cable Tray applications, checks the following aspects of your design for the following types of occurrences and other similar errors in the design. Angular Alignment Checks that components which are to be connected together are aligned in the same direction: Axial Alignment Checks that components which are to be connected together are aligned on a common axis: Consistent Bores Checks that components which are to be connected together have consistent bores: Connection Types Checks that components which are to be connected together have compatible connection types: Minimum Tube Length Checks that no length of tube is less than a prescribed minimum (which may depend on its bore).


100

www.aveva.com


8.1.1 Design Tolerances

The misalignment between adjacent components can be measured using any of the following three parameters. The offset distance between their p-arrive and p-leave axes The displacement angle between their p-arrive and p-leave axes The ratio of the offset to the projected distance between the p-arrive and p-leave p-points (equivalent to the tangent of the angle parameter). The user can specify maximum permissible values for any of these parameters, as well as minimum acceptable lengths of tube between components. The user can even specify different minimum lengths for different bore sizes. If any part of the design falls outside the current design limits, an error message will warn the user.

8.1.2 Starting the Data Consistency Checks

To carry out data consistency checking from within the Cabletray application, select Utilities > Data Consistency. You will see the following form: By using this form, you can generate a diagnostic report on the data consistency of any part of your design. You may list the report on your screen (in the area in the lower half of the form), or you may send it to a file from which you can print a hard copy version. Select Terminal or File and, in the latter case, specify the directory and filename. Choose The hierarchic level at which you want to check the design using the Check list near top left of the form. The default is the current element.

The data checking utility allows a margin of acceptable error before it diagnoses that you may have a problem. These built–in tolerances have default values, but you may set your own values if you prefer.


101

www.aveva.com


As an example, by default your report will warn you of all lengths of tube in your design which are shorter than 100mm. This allows you to decide whether each such length is adequate for welding procedures, bolt withdrawal, access, and so on. You can change the acceptable minimum length from 100mm, and may set different minima for up to ten different pipe bore ranges if you wish. For example: A minimum length of 150mm for bores between 25 and 50. A minimum length of 300mm for bores between 50 and 100. To change any of the consistency check tolerances, use the appropriate Parameters button on the form (Piping for our current examples). You will see a subsidiary form on which you can change any of the current tolerances before carrying out the data checks.

8.1.3 The Report Format

The report comprises a header, giving the date and time, followed by an itemised list of the elements being checked, together with numbered diagnostic messages describing any potential problems. For example: DATE 11 FEBRUARY 99 TIME 14.12 PIPE /PIPE2 BRAN /PIPE2/B1 B 10 TAIL REFERENCE NOT SET END

If no problems are found, you will see the message: *** NO DATA INCONSISTENCIES ***

8.1.4 The Diagnostic Messages

You will find a full list of the data consistency diagnostic messages, each identified by a reference number, in the Design Reference Manual. With experience, you will be able to identify which messages indicate errors which must be corrected, and which are merely warnings of potential problems. As an example, we will consider the design feature shown below, namely a Pipe to Pipe connection, and will look at some of the messages which might result. The connection as shown is a valid one. If any of the connection types were changed, you might see the following messages: A230 CONNECTION TYPE HCONN NOT SAME AS TERMINAL CONNECTION TYPE The connection types FBD-FBD in this example must be the same. B230 CONNECTION TYPE TCONN NOT SAME AS TERMINAL CONNECTION TYPE The connection types GBD-GBD in this example must be the same.

8.1.5 Some Examples of Diagnostic Messages

The following examples explain the significance of some of the messages you might see during this training course: Branch–Specific Diagnostics Branch Head Errors The following diagnostics apply only to the Head of a Branch: A 10 HEAD REFERENCE NOT SET The Head reference should only be unset (i.e. zero) if the Head Connection Type HCONN is set to OPEN, VENT, CLOS or DRAN. A 20 HEAD REFERENCE POINTS TO NONEXISTENT ELEMENT This error would result from the deletion of a component, such as a Nozzle, to which the Head of the Branch was originally connected. A 30 BAD HEAD RETURN REFERENCE The Head is connected to an element that does not refer back to the Branch. This can occur when the Head of a Branch is connected to another Branch, implying that a Tee should be placed somewhere along the second Branch. The error can also occur when two or more branches are inadvertently connected to the same terminal. A200 DIRECTION HDIR NOT SAME AS TERMINAL DIRECTION If the Head is connected to a terminal, such as a Nozzle or Tee, then the direction HDIR should always be identical to that of the appropriate p–point of the terminal. A210 POSITION HPOS NOT SAME AS TERMINAL POSITION If the Head is connected to a terminal, such as a Nozzle or Tee, then the position HPOS should always be identical to that of the appropriate p–point of the terminal. A230 CONNECTION TYPE HCONN NOT SAME AS TERMINAL CONNECTION TYPE If the Head is connected to a terminal, such as a Nozzle or Tee, then the connection type HCONN should always be identical to that of the appropriate p–point of the terminal. A300 REFERENCE HSTUBE UNSET There is more than 1mm of tube between the Head and the p–arrive of the first Component (or the Tail), but HSTUBE is unset. A310 REFERENCE HSTUBE REFERS TO A NONEXISTENT SPCOM This may occur if part of the Specification has been deleted. A320 HSTUBE PROBLEM, CATREF IN SPCOM IS UNSET This indicates an error in the Specification. A330 HSTUBE PROBLEM, CATREF IN THE SPCOM REFERS TO NONEXISTENT Catalogue COMPONENT This may occur if part of the Catalogue has been deleted or if the CATREF is unset. A400 HBORE NOT SAME AS BORE OF HSTUBE The bore of any tube leading from the Head, determined from the Catalogue, should always be identical to HBORE. A410 HCON NOT COMPATIBLE WITH CONNECTION TYPE OF HSTUBE The connection type of any tube leading from the Head, determined from the Catalogue, should be compatible with HCONN. A420 ISPEC REFERENCE POINTS TO NONEXISTENT ELEMENT This error would occur if, for example, the Insulation Specification pointed to by ISPEC had been deleted. Branch Tail Errors The same type of errors may occur to the Tail of a Branch. The message numbers are the same as for the Head errors but are preceded by a B. For example:


103

www.aveva.com


B 10 TAIL REFERENCE NOT SET The Tail reference should only be unset (i.e. zero) if the Tail connection type TCONN is set to OPEN, VENT, CLOS or DRAN. Plain Branch Errors The following diagnostics can occur only for Branches with no piping components: C500 TUBE TOO SHORT BETWEEN HEAD AND TAIL The distance between the Head position, HPOS, and the Tail position, TPOS, is greater than zero and less than the specified minimum tube length (default: 100mm). C510 BAD HEAD TO TAIL GEOMETRY Either the Head position, HPOS, does not lie at a positive distance along the line through TPOS in the direction TDIR or the Tail position, TPOS, does not lie at a positive distance along the line through HPOS in the direction HDIR. The following illustration shows some typical examples: C520 HBORE NOT SAME AS TBORE When there are no components on the branch, the Head bore, HBORE, should be identical to the Tail bore, TBORE. C530 HCONN IS NOT COMPATIBLE WITH TCONN This implies that the Head is connected directly to the Tail with no Tube or piping components in between; hence the Head connection type, HCONN, must be compatible with the Tail connection type, TCONN. C540 THIS BRANCH HAS NO COMPONENTS This does not necessarily indicate an error. It is output as a warning. Component–Specific Diagnostics The following errors apply to individual piping components and, in some cases, to their adjacent connections. Some of the errors also apply to Nozzles. All–Component Diagnostics These are applicable to any component, regardless of its position in the network: D100 REFERENCE SPREF UNSET This probably means that you have forgotten to choose the piping component correctly. D300 CONN REFERENCE NOT SET Multi–way Components may be left unconnected only if the connection type of the relevant p–point is OPEN, CLOS, VENT, DRAN or NULL. D310 CONN REFERENCE POINTS TO NON–EXISTENT BRANCH This may occur if the Branch which is pointed to by the CONN reference has been deleted. D320 BAD CONN RETURN REFERENCE This may occur if the Branch which is pointed to by the CONN reference has been reconnected to another terminal. D400 ARRIVE TUBE LESS THAN TUBE MINIMUM. ACTUAL TUBE LENGTH IS... The distance between the arrive p–point of this component and the leave p–point of the previous component (or Head) is greater than zero and less than the specified minimum tube length (default: 100mm).


104

www.aveva.com


D410 BAD ARRIVE GEOMETRY The position and direction of the arrive p–point of this component are not correct with respect to the leave p–point of the previous component (or Head). The error could be caused by incorrect positioning of this component, the previous component (or Head) or both. The following illustration shows some typical examples: D420 BAD ARRIVE BORE The bore of the arrive p–point of this component is not equal to the bore of the preceding tube or, if this component is not preceded by tube, to the bore of the leave p–point of the previous component (or HBORE). D430 BAD ARRIVE CONNECTION TYPE The connection type of the arrive p–point of this component is not compatible with the preceding tube or, if this component is not preceded by tube, to the connection type of the leave p–point of the previous component (or HCONN). D500 REFERENCE LSTUBE UNSET You have probably forgotten to select the piping Component. D600 LEAVE BORE NOT SAME AS BORE OF LSTUBE The bore of the leave p–point of this Component is not the same as the bore of the tube following the Component. D610 LEAVE CONNECTION TYPE NOT COMPATIBLE WITH CONNECTION TYPE OF LSTUBE The connection type of the leave p–point of this Component is not compatible with the tube following the component. End–Component Diagnostics These are applicable only to the last component in a Branch: E700 LEAVE TUBE LESS THAN TUBE MINIMUM. ACTUAL TUBE LENGTH IS... The distance between the leave p–point of the current component and the tail position, TPOS, is greater than zero and less than the specified minimum tube length (default: 100mm). E710 BAD LEAVE GEOMETRY The position and direction of the leave p–point of this component are not correct with respect to the position, TPOS, and direction, TDIR, of the tail. The error could be caused by incorrect positioning of this component, the Tail, or both. E720 LEAVE BORE NOT SAME AS TBORE The bore of the leave p–point of this component is not the same as the tail bore, TBORE. E730 LEAVE CONNECTION TYPE NOT COMPATIBLE WITH TCONN The connection type of the leave p–point of this component is not compatible with the tail connection type TCONN.

Exercise 8 (Data Consistency Check)

CHAPTER 9


9 Isometric Production

Detail Isometric production is the subject of other courses; however, since a requirement of all cableway designers is the production of check isometrics, the basic techniques of what is a simple operation are covered here.

9.1 Accessing Isodraft

Before An isometric can be produced, first ensure that cable tray(s) or branch(es) have been checked through the Datacon utility. The isometric will fail if components have lost their Spref (specification reference), are poorly aligned or overlap. A visual check, ensuring that no dashed line appears is not sufficient.

From design, Isodraft can be accessed using Design > modules > Isodraft.

Once in the Isodraft module, select Display > Members from the main menu. Members list is displayed showing the contents of the Design DB and a graphical view, similar to that in Design. Isodraft has a number of options to control the appearance, content and type of isometric. 2 alternatives are supplied each with an option to produce metric or imperial output data, thus giving 4 option files altogether. Before accessing 1 of these option files, using the Members form, navigate to a suitable cable tray or branch as you would in Design.


106

www.aveva.com


From the main menu, select Isometric > Standard The Standard Isometric form appears, the current element is that of the pipe in the hierarchy. The 3 option files are listed. Select BASIC.MET and then press the Apply button. This will generate an isometric in the graphical viewing area.

CE The member in the hierarchy becomes the current element.

Navigating to another cable tray or branch and then clicking the CE button will update the form and re-clicking apply will generate an isometric of the new cable tray or branch

Detail This can be changed to ’Detail List’ and several cable trays

or branches can be selected and multiple isometrics generated.

Produce This can be changed to generate: Transfer files Used to interface with other systems. Batch macro Useful when large quantities of isometrics are required. Any

such macro is usually run overnight. Bolt Report Bolts are only generated in Isodraft, so this function

generate a report of bolts for pipes and branches identified in the detail list.

Select Detail List from the Detail pull down, the Isodraft Detail List form appears. Select the Cable tray / trays or just a branch from the Members list and press Add


107

www.aveva.com


The ADVANCED options will not work on the cable trays you have created, since it requires part-numbers to be generated in the Design DB. This option is used in conjunction with the Spooler module of AVEVA Marine.

Default Isometric

9.1.1 Option Files

Within differing companies and the projects they undertake, there will be specific isometric requirements (backing sheet details, dimensioning, material list contents etc). It is the responsibility on the project administrator to create the option files required and inform designers of there significance.

Exercise 9 (Isometric Production)

Try producing isometrics of the cable trays you have designed. Ensure you have checked them with then the Data Consistency Checker and amended any significant errors before running Isodraft.

CHAPTER 10


10 Generating Reports

The AVEVA Marine database stores a large amount of 3D engineering information about user marine design. User can extract this data both graphically, in the form of drawings, or in text form, by producing reports. This session describes the principles and practice of producing reports. Users can produce a report by running a report template (Reports) or one based on their own selection criteria (Quick Reports) from within the Outfitting module.

10.1 Reports

The template specifies what the report will contain, whether it will be sent to the screen or a file, and how it will be laid out. There is a directory of example reports supplied with the product. This can be found in the directory $PDMSUI/REPORTS. Under this directory there is a TEMPLATES directory. This contains sample templates which can be used to generate standard reports. The templates are AVEVA Marine macros. The best way to see how they are defined is to select Utilities > Standard Reporting > Reports > Modify from the main menu, and look at the settings for the fields on the forms displayed.

Templates have the file extension .tmp, and the corresponding reports have a file extension .rep. Most of the examples are based on the sample project supplied with the product.

The sample templates produce the following types of report: catalogue_param This report lists Branch members, with their CATREFs and the parameters of the

CATREFs. catalogue_ptgmref This report lists Branch members, with their CATREFs followed by the PTREFs and GMREFs of the CATREFs. centre_line The centre-line length of each Branch is listed. There is also an Imperial version of

this report template. line_list This report will list Branches, sorted by the name of the Pipe which owns them. The

Pipe Specification, the Head and Tail bores and the Head and Tail references are given.

nozz_sched This is a Nozzle schedule, which lists all Nozzles sorted by name, and shows the P1 bore, connection type and direction, and the position of each Nozzle.

pipe_mto This report shows material information for all Branch members, sorted by type, Detail Text and Material Text. The Tube length and quantity of each component are totalled. There is an Imperial version of this report template.

steel_mto This is a material take-off list for structural components. tube_mto This report totals all Tubing. The Specification Reference, P1 Bore, Detail Text and

Material Text are shown. tube_gradient This report gives the gradient of each tubing component. tube_area_vol This report uses derived properties to report on the area and volume of tubing. valve_list This report is an example of selective reporting.

10.2 Running a Report from a Saved Template

The user may already be familiar with creating a report by running a saved report template. If not, try this introductory exercise. Select the following Utilities > Standard Reporting > Reports > Run The user will see a Windows File Browser, navigate to the location of the report templates, select the report template and click the Open button. The Report Details form will be displayed. On this form the user will need to complete all required fields. The information requested by this form is dependent on the settings of the Runtime Prompts form, defined during the template creation.

The Report Details form will be displayed. On this form the user will need to complete all required fields. The information requested by this form is dependent on the settings of the Runtime Prompts form, defined during the template creation. The information required by this form is totally dependent on what has been defined within the Template. Below are shown other questions that may be asked by the report template for certain Runtime Prompts. Filename If user specifies a filename, the report will be sent to the given file in the current directory. If user leaves this field empty, the report will be sent to the screen. Hierarchy Here user should specify the elements where report should start its searches. The report will be produced for all these elements and elements owned by them. Type(s) Here user should state all element Types that are to be reported on. The report will be produced for all the elements given.

With Defines the criteria that must match the elements before they will be reported on. This is sometimes referred to as a filter but works in the same way as the other occurrences in AVEVA Marine. Volume Allows the setting of Limits. The report may be generated on elements that are Completely Within or Partially Within the limits. From Allows the user to specify where the search will take place. The Default is MDB

10.3 Quick Reports

The Create Quick Report form is displayed when user select Utilities > Standard Reporting > Quick Reports from the main bar menu. This form allows user to create reports with only basic formatting and this

template cannot be saved. User can enter a filename for the output report. If user just wants to see the report on the screen, leave the

File text box blank, or press the Term button, in which case any filename given will be ignored. If Term is

selected, a window will be displayed to show the results or the report, unless there is already a form currently displayed to which the results may be written to. The options performed by the buttons on the Quick Reports form are:

Types AVEVA Marine element types can be specified. i.e. BRAN MEM BEND ELBOW TEE

With This option is a way of narrowing down the report. Enter a AVEVA Marine expression, i.e. HBORE LE 75


112

www.aveva.com


Columns These are the AVEVA Marine attributes to output of the report. The attributes specified will

be used as headings to the column. User can enter expressions, enclosed in round brackets. The following example outputs the type, name, and the first three characters of the owner's name.i.e.TYPE NAME (SUBSTR (NAME OF OWNER, 1, 3)) or NAME OWNER HPOS TPOS

Hierarchy Enter the element or elements at the top of the hierarchy that user wants to report on.

Because user can give a list of elements which are entered with a slash character before each name, except for WORLD. i.e. /CTRAY_YY010

10.3.1 Run the Report

Press the Run the Report button when ready to generate the report.

Exercise 10 (Reports)

1. Run the report cabletray_sched.tmp to show the type of output created. This Report Template will

be supplied by the trainer, nd can be saved locally. 2. Create a report to list all the cable trays with spec /SCTG. Create columns to display Name, Pspec,

Hbore, and Tbore 3. Create a line list report and experiment with the sorting facility and notice the way it changes the

output.
