Positioning Radial Nozzles

Method 1

1. Create and then position the nozzle to the correct Up coordinate only. P1 should point in the correct direction, i.e. E 45 N.

2. From the application menu bar, choose: Position > Move > Distance The direction of movement is the same as P1. The distance is the PROJECTION DISTANCE. Note: If the nozzle’s height is set from face to centerline, you might use Position > Relatively (BY)

and define the relative

movement as the offset from P2 to P1.

Solid line nozzle shows position after Step 1. Dashed line nozzle shows position after Step 2.

Method 2

1. Create and then position the nozzle at the correct Up coordinate and position it to an orthagonal direction the PROJECTION DISTANCE away from the equipment centerline, i.e. E 2’9. P1 should point in the orthagonal direction, i.e. E.

2. From the application menu bar, choose:

Orientate > Rotate The rotation axis should pass through any point on the equipment centerline, i.e. CYLI origin, DISH origin, EQUI origin, etc. Change the ‘wrt’ to WORL, SITE, ZONE, or EQUI if required.

PSEUDO ATTRIBUTES

In order to get specific information directly from the database, a number of keyword or pseudo attributes have been introduced. Pseudo attributes are not attributes as such, but they have the ability to extract data when queried. For Example

ELBO 1 --->>>> Go to elbo 1 of the branch

Q PARAM --->>>> Query the parameters of the catref of the spref

Q DTXR --->>>> Query the rtext of the detref of the spref_ can also use dtxs or dtxt

Q MTXX --->>>> Query the xtext of the matref of the spref _ can also use mtxy or mtxz

Q PURP XXX --->>>> Query the purpose attribute of the property XXX

Piping Attributes

Q CHOICE --->>>> Query the answers of the selectors of the spref

Q CHOICE STYP --->>>> Query the styp used to select the component

Q PL BOP --->>>> Query the bottom of pipe elevation of the leave point

Q PA INSU --->>>> Query the insulation thickness at the arrive point

Q APOS --->>>> Query the arrive position

Q LPOS --->>>> Query the leave position

At Branch Level

Q TULEN --->>>> Query the length of tube in a branch

Q CLLEN --->>>> Query the centerline length through all components

Steelwork

Q ODESP --->>>> Query the design params of the joint owner

Q ADESP --->>>> Query the design params of the joint attached beam

Q DRPS --->>>> Query the derived position of the beam start

Q NWEI -->>>> Query the net weight (considering joint cut outs)

Q GWEI --->>>> Query the gross weight (beam before cutting)

Q NCOF --->>>> Query the net centre of gravity for the beam

Q POS PPLINE TOS START WRT /* --->>>> Query TOS of current element (SCTN)

Q PPLINE TOS DIR --->>>> Query the direction of the TOS pline on a SCTN

PDMS Syntax Examples

Position>Move>Distance

Moves the element’s origin by a given distance in a given direction.

Ex. MOVE N DIST 10’MOVE S WRT /* DIST 5'

MOVE E IN SITE DIST 5'

Position>Move>Through

Moves the origin of the element in a given direction through a Reference Plane perpendicular to the line of travel that is passing through a picked element, p-point, or coordinate.

Ex. MOVE N THRO ID@MOVE N THRO IDP@

MOVE N THRO N46’

Position>Move>Clearance

Moves the element’s origin, p-point, or obstruction in a given direction with a clearance from another item’s origin, p-point, or obstruction.

Ex. MOVE E DIST 10’ FROM /P-101MOVE E CLEARANCE 10’ FROM /P-101

The options INFRONT, BEHIND, ONTO, and UNDER refer to a picked or named item’s physical obstruction, while the TO and FROM options refer to the item’s origin. INFRONT and TO refer to the near side while BEHIND and FROM refer to the far side of an item.

Position>Plane Move>Through

Moves the origin of the element in a given direction through a Reference Plane specified by the user that is passing through a picked element, p-point, or coordinate. Ex. MOVE ALONG E PLANE N45W THRO ID@

AT E3’ N30’ U10’ -- Position the current element at a specific coordinate (must specify all three coordinates)

BY E6’6 -- Move the current element a relative distance in a given direction

TO U12’6 -- Move a piping component to one specified zone coordinate along constrained centerline

Q POS PPLINE TOS START WRT WORL -- Query TOS of current element (SCTN)

Q EVAR PDMSUSER -- Query the operating system location of user file directory (%PDMSUSER%)

NEW STRU -- Create new structure element (Note: CE must be a owner level (ZONE) or below

NEW SUBS /MAIN-DECK -- Create new substructure element and set the name attribute

POS E20’ N10’ U5’ -- Position CE at specified owner coordinates

POS E20’ N10’ U5’ WRT /* -- Position CE at specified world coordinates

CONN IDP@ TO IDP@ -- Connect a picked Ppoint on the current primitive to a picked Ppoint of another.

CONN P1 TO IDP@ -- Connect P1 of the current primitive to a picked Ppoint of another primitive.

Setting PDMS attributes

In principle, any attribute can be set by specifying the attribute name and value you want it to take. The following are examples:

XLEN 200

DESC 'PLATE GIRDER'

HEIGHT 300

TEMP 120 NAME /FRED

PURP EQUI

ORI Y IS N

ORI Y IS N AND Z IS U

Navigation

Commands for moving around the PDMS database.

/NAME - Move to an element by name

=23/506 - Move to an element by its reference number

END - Move up the database hierarchy by 1 level

6 - Move to the sixth element in the list of the current element

NEXT - Move to the next element in the list at the same level

NEXT 2 - Move to the second element after the current element

NEXT ELBO - Move to the next elbo in the current list by passing any other elements

PREV - Move to the previous element in the list

PREV 4 - Move four elements back from ce

SAME - Go to the previous current element

NOTE: NEXT and PREV commands work on the list according to the modes Forwards or Backwards. In backwards mode, the list is considered to be reversed so these commands have the effect of working from the opposite end of the list.

Orientation Commands (General)

ORI Y IS N AND Z IS U --->>>> This is the default orientation (wrt owner) for all elements that have an orientation attribute.

ORI Y IS E45N --->>>> Specify that the Y axis is pointing E45N. When only one axis is specified, the other tries to get to it's default, so in this case, Z will default to UP.

ORI P1 IS N --->>>> Rather than specifying an axis, this command specifies that a particular ppoint is to be orientated in the direction specified.

Orientation Commands (Piping)

ORI --->>>> This command orientates the arrive of the element in the opposite direction to the leave of the previous element. It does not change the position.

CONNECT --->>>> Perform an ORI, then position the arrive at the leave of previous.

DIR S --->>>> This is a special command which is allowed to change the angle of a component. It first performs an ori, then adjusts the angle to ensure that the leave direction is in the direction specified.

ORI AND P3 IS U --->>>> Used for valves, tees, etc., this command performs an ori and then points the ppoint in the required direction. It does not change the angle.

DIR AND P3 IS U --->>>> This is another special command which is only used on tees with variable angles. (Usually for sloping lines.) In this case, the tee is orientated and the angle adjusted to allow p3 to point in the direction specified.
