PrefaceVersion 5 Structure Functional Design allows you to enrich the conceptual design of structural elements. It offers an easy-to-use and easy-to-learn graphic interface.

The overall ship design project goes through a number of different phases from conceptual design through functional and detail design to extraction of deliverables. This product addresses functional design requirements for the shipbuilding industry. It builds on conceptual design letting you refine and strake the hull, add plate thicknesses to decks and major bulkheads, define longitudinal and transverse stiffener systems. It also permits calculation of ship strength as well as early weight, labor and material estimates.

As a scalable product, Structure Functional Design can be used with other Version 5 products such as Generative Shape Design and Generative Drafting.

Shell Tools Shell tools are used to assist you in the creation of plates and stiffeners on the hull or on high-curvature surfaces.

When using shell expansion tools, you should work on hull form halves (starboard or portside surfaces) or a section of the hull form and not the complete hull form.

The imported hull form must not include faces perpendicular to the projection plane, typically the transom must be considered a bulkhead and not an integral part of the hull. Nor must the imported surface be closed, i.e. delimit a volume.

Define plate traces: lie hull flat using the Shell Expansion command, sketch plate traces then import result back using the Import Shell Expansion command

Define stiffener traces: lie hull flat using the Shell Expansion command, sketch stiffener traces then import result back using the Import Shell Expansion commandDefine shell spline traces: select a body line, click to locate point then click Add Point and repeat.


Defining Plate TracesYou can sketch plate traces on the hull using shell expansion tools. This is done in three steps:

6. Select an attribute in the Attribute field and click the Add button. The attribute will be added in the window. Add as many attributes as you want to.

7. You can further refine your report by using the Edit - Search function to define a query. This will allow you to generate a report on a narrower selection of check valve, say, of a certain size, instead of all check valves in your document. The queries you create will be available for selection when you click the arrow in the Query Name field above. Detailed instructions on using the Search function can be found in the Infrastructure User Guide under Basic Tasks - Selecting Objects. Briefly, click Edit - Search to bring up the Search dialog box. Select the Advanced tab, then select a workbench, type of object and attribute you are interested in. Clicking the Add to Favorites button brings up the Create a Favorite Query dialog box, where you can name the query and save it.


Generating a Report

This task explains how to generate a report listing values of selected properties. Before you do this you need to define the report format.

Examples form the Piping Design workbench are used here. Substitute the appropriate resource or directory when working in another workbench.

1. Click Tools - Report - Generate. The Generate Report dialog box displays.

2. Click the Open button and select the format you want to use for your report, in this case NewReport.3. If you had defined a query in your report format then check Objects From Predefined Query.4. If you select one or more objects in the document then check the option Currently Selected Objects.5. Check All Objects in Document if you want a report on all objects in your document.6. Click OK and select a format, such as HTML, when you are prompted. The report will be generated. It shows

values for all properties defined in your report format for all objects in the document that have them. Where an object does not have a property the report displays asterisks.


7. Click Insert in Doc if you want to display these values in your document. To generate the report from a schematic and insert it in a schematic, click on the Insert in Doc button and click anywhere in your drawing. To generate the report from a 3-D document and insert it in a schematic, click on the Insert in Doc button and select the sheet or view in the specifications tree. Do not select a point in the sheet. The data will be placed at the origin of the sheet or view, and can be moved to another location.

8. Click Save As to save the report. Specify a file name and location.


Producing DrawingsGenerative view styles are used to produce structural drawings. These view styles let you customize the appearance of drawings via a set of parameters defined in an XML file. It is the administrator's job to provide suitable styles.For more information on generative view styles and other drafting capabilities, see the Generative Drafting User's Guide.

This tasks shows you how to produce drawings using generative view styles.

A Generative Drafting license.

1. Open your 3D document.

2. Specify your settings before you start: ● Select Tools ->Options ->Mechanical Design->Drafting->Administrator

● Uncheck Prevent generative view style creation

This activates generative view style functionalities.


3. Create a new drawing: ● Select Start -> Mechanical Design -> Drafting.

You switch to the Drafting workbench and the New Drawing Creation dialog box appears.

● Select the view you want to create.

● Click OK in the New Drawing Creation dialog box.

4. Click the Front View icon.

7. Click inside the sheet to generated the view.

Use Technological Feature Dimensions commands to dimension functional stiffeners and stiffening in the graphic replacement mode.


Using Generative View StylesThis section intends to give you information about generative view style parameters for the following applications:

● Common to all applications

● Equipment Support Structures

● Structure Functional Design

● Ship Structure Detail Design.

Customizing these parameters is an administrator task. The following sample XML files are supplied:

● EquipmentSupportStructureSample.xml

● StructureFunctionalSample.xml

● StructureDetailSample.xml

Sample files are located in ../OS/startup/EquipmentAndSystems/DrawingExtraction/GVSSamples.

It is recommended that the administrator customize these files. When finished, files must be placed by default in ../OS/resources/standard/generativeparameters to make them available to the user.The administrator must also set the generative parameter "wireframe" in the DefaultGenerativeStyle.xml to Yes so that the user obtains suitable drawings using generative view styles.

Appropriate application licenses including one for Generative Drafting are required.

For information on how to customize parameters, how to create views using generative view styles, or more generally on generative view styles, see the Generative Drafting User's Guide.

Managing User Sections

Sketching ProfilesDefining anchor points

Creating and Completing Parametric Section Catalogs


Sketching Profiles for User Sections

This task shows how to sketch profiles for user sections using Sketcher capabilities.


1. Start the Sketcher workbench (Start ->Mechanical Design ->Sketcher).

2. Select the xy working plane in the geometry area or specification tree.

The Sketcher workbench is displayed.

User sections created using Sketcher capabilities must be created in the xy plane.

3. Sketch your profile, for example use the Circle icon to

sketch a simple circle that will give a round bar or circular tubing section:

● Point where you want to place the center of the circle.

● Drag to set the radius.

● Click when satisfied.

Note: It is recommended that profile dimensions match actual section dimensions.

4. If desired, set constraints.

5. Exit the sketcher.

6. Using File -> Save, save the sketch as a CATPart document in the folder dedicated to storing available sections defined in your settings (see the Customizing section of this guide).

Your sketch now appears as a resolved section in the Section list of the appropriate dialog box. You are now ready to use it to create a structure.


For more information on sketching profiles and setting constraints, see the Sketcher User's Guide.


Defining Anchor Points for User Sections

Anchor points can be defined on user-defined parametric sections.

Note: All resolved sections automatically inherit the defined anchor point.

This task shows how to define an anchor point.


1. Edit the sketched section.

2. If the anchor point you want to define does not correspond to an existing point of the sketch, create an appropriate construction point.

3. Rename the point: ● Right-click the point and select Properties from

the contextual menu.

● Select the Feature Properties tab in the Properties dialog box.

● Rename the point using the prefix catStr, for example catStrUserAnchorPoint.

4. Exit the sketcher, then save the sketch as a CATPart document (File ->Save).

5. Return to the Structure Design workbench:

The new anchor point is automatically added to the Anchor point list. All user

anchor points are accompanied by the following symbol: to distinguish them from standard anchor points.

Anchor points WebSideLeft, WebSideRight and WebCenter are supplied with the product for L, T and bulb sections. These anchor points are considered user

anchor points and share the same anchor point symbol:


Creating & Completing Parametric Section Catalogs

This task shows how to create a user catalog for parametric sections.

You can create user catalogs in three different ways:

● Using the Catalog Editor with one sketch corresponding to one family and linked to one design table.

● With a Part Family in Batch Mode with one sketch corresponding to one family and linked to one design table.

● In Batch Mode where one sketch is used for several families and design tables are not linked to the sketch. These catalogs are built in the same way as the sample catalogs supplied with the product.

Sample CatScript documents are provided to illustrate the batch mode and will be mentioned below at the appropriate step in the task. They are to be found in the online documentation filetree in the common functionalities sample folder, cfysa/samples.

Creating a Catalog using the Catalog Editor

This first task introduces the Catalog Editor workbench which provides interactive commands to create your own catalogs.

1. Make a USER directory with the same name as your catalog and sub-directories for sketches and design tables: ● USER/Sketches

● USER/DesignTables.

2. Sketch the profiles for your user sections and store in the USER/Sketches directory.

Standard sketches of parametric sections (I, U, L, T, double U, double L, bulb and tube shapes) supplied with the product are located in the directory install_folder/startup/components/StructuralCatalogs/Sketchs.

3. Create design tables, naming the header in the first column PartNumber.

Note: You can create design tables in two ways:

● Independently of sketches, in which case you must link tables to sketches (ensuring that design table column headers correspond to sketch parameters).

● Based on the sketches, in which case no linking is necessary.

Design tables contain the geometric parameters used to generate the section.

4. Use the Catalog Editor to create your catalog: ● From the Start menu, select Infrastructure ->Catalog Editor to open the Catalog Editor workbench.

● Use the Add Part Family icon for Structure Design catalogs.

For more information, see Creating a Catalog using the Catalog Editor in the Infrastructure User's Guide.

Creating a Catalog with a Part Family in Batch Mode


1. Make a USER directory with the same name as your catalog and sub-directories for sketches, design tables and CSV files: ● USER/Sketches

● USER/DesignTables

● USER/CSVFiles

● USER/VBScript.



3. Create design tables, naming the header in the first column PartNumber.

Note: You can create design tables in two ways:

● Independently of sketches, in which case you must link tables to sketches (ensuring that design table column headers correspond to sketch parameters).

● Based on the sketches, in which case no linking is necessary.


4. Create a CSV-type file for Chapters.

CSV files map family names to appropriate family catalogs.

Chapters correspond to the first level in a catalog and provide a way of classifying other chapters or families.

Typical CSV file:

CHAPTER;DIN;I_SectionCatalogDIN;Keywords;Family;Types;String;;Quadrat_Hohlprofile;e:\users\jcm\StructuralCatalogs\USER\Quadrat_Hohlprofile.catalog;Rechteck_Hohlprofile;e:\users\jcm\StructuralCatalogs\USER\Rechteck_Hohlprofile.catalog

5. Create ENDCHAPTER and CHAPTER CATScripts.

Sample CATScripts are given below. They are to be found in the online documentation filetree in the common functionalities sample folder, cfysa/samples.

6. You are now ready to run the batch operation:

● Start a Version 5 session

● Select Tools ->Macro ->Macros...

● In the Macro dialog box, set Macro in to External File

● Select the appropriate CATScript, then click Run.

It is important to run the CATScript generating the families (END CHAPTERS) before the one generating the chapter (CHAPTER) since the chapter references the families.

Creating a Catalog in Batch Mode1. Make a USER directory with the same name as your catalog and sub-directories for sketches, design tables and CSV files:

● USER/Sketches

● USER/DesignTables (this sub-directory must be named DesignTables)

● USER/CSVFiles

● USER/VBScript.



3. Create design tables.

Note: Do not link design tables to sketches.



4. Create CSV-type files for End Chapters and Chapters.

CSV files map section names to appropriate parametric sketches.

END CHAPTER Conventions

End chapters correspond to catalog families. A family is a set of components.

For example, ENDCHAPTER: Name;Icon;DesignTable;

● If the design table is not linked to a sketch, the name of the design table must be the last parameter in the first line starting ENDCHAPTER.

● The first keyword must be Section

● The full path name of documents must be given.

Typical CSV file:

ENDCHAPTER;HEA;I_SectionStructureI;OTUA_HEA;Keywords;Section;Types;String;HEA100;HEA100;e:\users\jcm\StructuralCatalogs\Sketches\IShape.CATPartHEA120;HEA120;e:\users\jcm\StructuralCatalogs\Sketches\IShape.CATPartHEA140;HEA140;e:\users\jcm\StructuralCatalogs\Sketches\IShape.CATPart

CHAPTER Conventions

Chapters correspond to the first level in a catalog and provide a way of classifying other chapters or families.

Typical CSV file:

CHAPTER;DIN;I_SectionCatalogDIN;Keywords;Family;Types;String;;Quadrat_Hohlprofile;e:\users\jcm\StructuralCatalogs\USER\Quadrat_Hohlprofile.catalog;Rechteck_Hohlprofile;e:\users\jcm\StructuralCatalogs\USER\Rechteck_Hohlprofile.catalog

CHAPTER

● Open the file USER_Chapter.CATScript. In our example, the content is as illustrated above.

● f you want to use it, copy it and change the User customizable sections to adapt them to your environment, or copy a sample CATScript from the one of the standard catalogs supplied with the product and change it.

6. You are now ready to run the batch operation:

● Start a Version 5 session

● Select Tools ->Macro ->Macros...

● In the Macro dialog box, set Macro in to External File

● Select the appropriate CATScript, then click Run.

It is important to run the CATScript generating the families (END CHAPTERS) before the one generating the chapter (CHAPTER) since the chapter references the families.

Completing Parametric Section Catalogs


This task shows how to add sections to existing catalogs.

To add sections to existing catalogs, you must rename the path of linked documents in CSV files because these files contain the full path name. To do so, one Excel file per sample catalog containing an appropriate macro is provided. For example, the Excel file for the OTUA catalog is OTUA_hierarchy.xls. Excel files are located in the CsvFiles directory.

1 Edit the Commands sheet of the appropriate Excel file, entering the necessary information.

Note: The first sheet named Data contains all CSV files in the catalog.

2. Click Modify absolute path of pointed CATPart in CSV files to rename the path.

3. Add new sections.

4. Generate the catalog as above.


Mirroring Systems Using Assembly Design ToolThis tasks shows you how to create a new system by mirroring an existing system around a plane. In our example, a panel system for part of the hull is copied from portside to starboard.

The command used, Symmetry, belongs to the Assembly Design workbench.Since the new system created will be a mirror image, it is important to ensure that this is indeed what you want. In our example, the hull form, stiffener traces and web orientation are exactly symmetrical.

Have prepared the system (panel, plate or stiffener) you want to copy.

No sample document is provided.1.Activate the parent system containing the one you want to copy.

2.If necessary, show the symmetry plane, in our case the ZX plane.

3.Switch to the Assembly Design workbench (Start -> Mechanical Design -> Assembly Design).

4.Click the Create symmetry on component icon or select Insert ->

Create symmetry.

The Assembly Symmetry Wizard appears.

5.Select the symmetry plane, in our case the ZX plane.

6.Select the system to be mirrored, in our case UnspecPanelSystem_024, then click Finish in the Assembly Symmetry Wizard.


The mirrored system is previewed.

The Assembly Symmetry Wizard expands and displays the list of entities that will be copied.

Keep Link Options

● Keep link in position: if checked, any changes to the position of the original system will be propagated to the mirror system.

● Keep link with geometry, if checked, any changes to the geometry of the original system will be propagated to the mirror system.

7.Click Finish to confirm the operation.

A window appears displaying the results.

8.Control the results in this window, then click Close.

A new system, the mirror copy of the first, is created.

Managing Your ProjectWorking with a Cache System

Organizing Data using a Work Breakdown StructureUnderstanding Project Resource Management

About the Feature DictionaryAbout Object Naming RulesAbout Molded ConventionsAbout Project Parameters


Working with a Cache SystemTo improve system performance when working with very large documents, it is recommended that you activate the cache.

This means that documents will be loaded in visualization mode, however, when editing structural items such as stiffeners, the item is automatically switched to design mode. Any new structures are created in design mode in the document.

The cache system is managed via the Cache Management tab in the Options dialog box (Tools -> Options -> Infrastructure -> Product Structure).


Organizing Data using a Work Breakdown Structure

You can structure and organize your data using a work breakdown structure (WBS). This avoids creating intermediate component nodes in the structure tree which create an unnecessary level of instantiation.

It is recommended that you create all panel systems directly under the root product.

To take advantage of WBS:

1. Create panel systems directly under the root product.

2. Create WBS views and generic components (GCOs).

3. Organize your panel systems by dragging and dropping them under appropriate WBS views.

4. Save your document.

This enables you to load only views of interest.


Understanding Project Resource ManagementProject resources are managed by system administrators. Typically this involves entering information such as folder paths for resources, like user dictionaries such as the feature dictionary, without which the application cannot function. What administrators enter will be visible in the Browse tab of the Project Resource Management dialog box (Tools -> Project Management), but it cannot be changed there.

A sample project resource management file is provided with this application and by default, the application will start with this file. Resources managed in this file are listed below.

Project Resources

● Feature dictionary managing object classes

● Discrete values for attributes: directory used to store discrete values of attributes.

● ID schema managing object naming rules

Structure Discipline Resources

● Project parameters: contains setup parameters for ship directions and characteristic planes

The default location for this resource is ../OS/startup/EquipmentAndSystems/Structure

● Molded conventions: contains a set of rules that give default orientations when placing structural elements

The default location for this resource is ../OS/startup/EquipmentAndSystems/Structure

● Orientation conventions: contains naming conventions for ship directions. Default conventions are USA conventions contained in sample CATStrOrientNamingUSAConv.

Sample naming conventions for European conventions is also supplied: CATStrOrientNamingEURConv.

The default location for these resources are .../OS/resources/msgcatalog

● Structure drawing symbols catalog

The default location of this resource is.../OS/startup/components/StructuralCatalogs/DrawingSymbols/Structure2DSymbols-Customization.catalog


● Standard section catalog

The default location of this resource is .../OS/startup/components/StructuralCatalogs/AISC/AISC_StandardScale.catalog

● Structure resolved sections path: identifies the path of the folder in which the list of available sections

will be stored.There is no default location for this resource; the location shown is given as an example.

To set this path:

- Uncomment this entry- Identify the path.

It is recommended that you create an empty folder for available sections and that you identify the path to this folder in a customized project resource management file. You can also, if desired, initialize a section list for the user.

If no path is identified here, the path set in your settings is taken.

You can create a catalog of available sections and store it in ENOVIA.

● Thickness table: manages plate thicknesses. A sample table in text format is supplied. The system

administrator can modify or add to the sample thickness table, or, if needed, create a new table.

The default location of this resource is .../OS/startup/components/StructuralCatalogs/ThicknessTables/ThicknessListSample.txt

Important: If you change a thickness value in an existing design table, all plates of this thickness linked to the design table will be updated to the new value. With this in mind, you may prefer to add a row for the new thickness or create a new table.

● Structure materials catalog: defines all material-grade combinations available.

Note: Associated tiffs are not provided. This means rendering is unavailable.

The default location for this resource is .../OS/startup/components/StructureCatalogs/Materials/StructureMaterials.CATMaterial

This catalog can be stored in ENOVIA. To reference the ENOVIA catalog as the project resource, enter the name of the catalog (no extension) and set the driver to EnoviaV5.


● Opening catalog

The default location of this resource is .../OS/startup/components/StructuralCatalogs/OPENINGS/SFD_Openings_StandardScale.catalog

where OS is the operating system, for example intel_a (Windows)

If there is more than one project at your site, then a project resource management file is made for each project. You can open another resource management file using the Project Management command (Tools -> Project Management). For more information on how to do so, see Using the PRM command in the Infrastructure User's Guide.

For more information on resources and how the resource management file is organized, see Understanding Project Resource Management in the Infrastructure User's.

Managing project resources is typically performed by an administrator.


About the Feature DictionaryThe feature dictionary manages object classes and lets you set default values for class attributes managed. In the sample dictionary provided with the application, three object classes are managed: panel systems, plate systems and stiffener systems.

Note: In the application, these object classes are managed via the class browser.

To view the sample dictionary:1.Open the CATStructureFunctionalDesignSample.CATfct file.

By default, this file is located in the install_folder under /resources/graphic.

The Feature Dictionary Editor opens showing the sample dictionary.

The Classes View lists all the classes available in the document, i.e. the predefined classes and sub-classes included in the application.

2.Expand the Classes View to display predefined classes.

3.Double-click the Plate System to view system attributes.

Existing attributes or properties are displayed in the Inherited attributes and Local attributes boxes. Inherited attributes are those inherited from the super class to which this class belongs. Local attributes are properties added to the class itself.


The following table lists the object classes and corresponding attributes provided in the sample dictionary.Panel System

● None

Plate System● Side Orientation

● Material

● Thickness

Stiffener System● Side Orientation

● Material

● Section

Attributes or properties assigned to object classes can be browsed via the Properties dialog box (right-click the feature in the specification tree and select Properties from the contextual menu).

You can add sub-classes and attributes to the sample dictionary, or if you want, you can create a new feature dictionary. You can in this way specify molded conventions for plate and stiffener systems for example.Material

Specifying a material in the feature dictionary for plate and stiffener systems defines the default material for these systems in the Properties dialog box as well as sets the default material proposed when creating functional plates, insert plates, stiffeners, twisted profiles and pillars. If no value is given, the default material is that set in the application settings.The material specified in the feature dictionary must be compatible with material names in the project structure materials catalog.

Thickness

Specifying a thickness in the feature dictionary for plate systems defines the default thickness for plate systems in the Properties dialog box as well as sets the default thickness proposed when creating functional and insert plates. If no value is given or if the value is not in the thickness table, the default thickness is taken from the thickness table. The thickness specified in the feature dictionary must exist in the project thickness table.

Section

Specifying a section in the feature dictionary for stiffener systems defines the default section for stiffener systems in the Properties dialog box as well as sets the default section proposed when creating stiffeners, twisted profiles and pillars. If no value is given, or if the section is not in the available sections folder, the default section is the first section in the available sections folder.The section specified in the feature dictionary must exist in a project section catalog and must also be stored in the available sections folder.

For more information, see Using the Feature Dictionary Editor in the Infrastructure User's Guide.


About Object Naming RulesStructure Functional Design provides a set of default naming rules or unique identifiers for the objects you create. This identifier consists of a prefix that identifies the type of object it is, followed by a unique number.

You may want to modify these rules to suit your own requirements:

● For objects (panel system, plate system and stiffener system) integrated in the feature dictionary, use the Define/Modify ID Schema command in the Feature Dictionary Editor application.

● For all other objects, you must edit XML files directly.By default, sample XML files are located in the install_folder under startup/EquipmentAndSystems/StructureFunctionalDesign/DataDictionary.

Modifying or defining object naming rules is typically performed by an administrator.

For more information, see Modifying the Object Naming Rules in the Infrastructure User's Guide.


About Molded Conventions

Molded conventions are a set of rules that give default orientations when placing structural elements, thereby ensuring structural continuity. These conventions are described in an XML file (MoldedConventions.xml) referenced in the Project Resource Management (PRM) file.

The default location for this file is ../OS/Startup/EqiupmentAndSystems/Structure

This file describes conventions for plating and stiffening of both Structure Functional Design and Ship Structure Detail Design products. Plating and stiffening are oriented according to their location in the hull and with respect to the midship or centerline. Midship and centerline definitions are specified in another XML file describing project parameters (ProjectParameters.xml). Important: Conventions are specified for each object class of paneling or plating and stiffening defined in the feature dictionary.

Molded conventions cannot be applied to Structure Functional Design stiffeners whose trace curves are defined using the Sketcher.

Placing Structural Elements

The system administrator can modify the following information:

● ThicknessOrient: the side of the support on which plating thickness is oriented


● WebSideOrient: the side of the plating on which the stiffener is placed

● FlangeOrient: orientation of the stiffener flange

● AnchorPoint: the point at which the stiffener section is anchored along its trace.

The default value is WSL (web side left).

Symbols Used

The following letters are used to describe how structural elements are placed:

● P: in the positive direction of one of the main ship directions, regardless of the midship or centerline

● M: in the negative direction of one of the main ship directions, regardless of the midship or centerline

● I: towards the midship or centerline

● O: away from the midship or centerline


Do not change names of feature dictionary classes.


About Project Parameters

Project parameters are managed as project resources and are described in an XML file (Project Parameters.xml).

The default location for this file is ../OS/Startup/EqiupmentAndSystems/Structure

This file describes:

● Ship coordinate system or front orientation.This is done by specifying the orientation of the x-axis that runs the length of the hull. Two values are possible:

Xm: the origin is located foreward and positive distances proceed aft. This corresponds to USA orientation conventions.

Xp: the origin is located aft and positive distances proceed forward. This corresponds to European orientation conventions.

● Location of the midship and centerline.

This information is used by the xml file describing molded conventions.

● Units in which values in this file are given.Consistency between units specified in this file and those set in CATIA (Tools -> Options -> General -> Parameters and Measure -> Units) is ensured.

Do not change the names (MidShip, CenterLine) given to characteristic planes.


Knowledgeware CapabilitiesStructure Functional Design Package in Knowledge Expert

Design RulesUsing Checks to Position Openings


Structure Functional Design Package in Knowledge Expert

A Structure Functional Design package is supported by Knowledge Expert. This package can be accessed via the object browser and objects, attributes and methods in the package used in expert relations. You can, for example, write a rule to change the colour of all members whose weight is greater than a specified value.The package contains the following objects.

● CATStrFunInsertPlate

● CATStrFunOpening

● CATStrFunPillar

● CATStrFunPlate

● CATStrFunStiffener

● CATStrPanelSystem

● CATStrPlateSystem

● CATStrStiffenerSystem

Note: CATStrFMFSkeleton has been exposed to permit interference checking on panel systems.

All other objects listed in the browser derive from the above main objects. These objects or sub-classes are managed in the sample feature dictionary.


For information on object attributes and methods, see Structure Functional Design in the Reference Information section of the Knowledge Expert User's Guide.


Design RulesA sample catalog containing knowledgeware design rules for the following three structure objects is supplied with the product:

● Functional plates

● Functional openings

● Functional stiffeners.

The default location for this catalog, Structure Design Rules, is:

downloaddirectory/intel_a/startup/EquipmentAndSystems/StructureFunctionalDesign/DesignRulesFunctional Plates

Three design rules set plate color as a function of plate thickness.

Typical rule syntax:

if (P\Thickness == 10mm) then P->SetColor(255,0,0)

Functional Openings

Two design checks verify that openings are correctly located with respect to other parts or part boundaries.

Check syntax is as follows.

Clearance from Functional Molded Form boundaries:O->ClearanceWithOpening (200mm)

Clearance between openings:O->ClearanceWithOpeningDiameter (200mm)

For more information on writing your own checks to position openings.

Functional Stiffeners

One macro and one check starting the macro are provided.

The macro finds all user attributes of structural members under the active product and returns the name of the active product. Product information can then be read in Product tab of the Properties dialog box.


Check syntax is:

the Tools -> Macro -> Macros command.

● You can display the bill of material you generate in the Assembly Design workbench using Analyze -> Bill of Material... Don't forget to show hidden properties (Define formats command in the Bill of Material dialog box).

You can save BOMs in html or txt formats for subsequent use.

For more information on: ● How to use the design rules stored in this catalog, see 'Using a Rule Base Stored in a Catalog' in the Knowledge Expert

User's Guide.

● Macros, see the Infrastructure User's Guide.

● The Bill of Material command, see the Assembly Design User's Guide.


Using Checks to Position OpeningsYou can use expert checks to verify that openings are correctly located with respect to other parts or part boundaries. You can, in this way, write checks to detect whether or not a given minimum distance is respected between:

● an opening and a panel system boundary

● the contours of two openings. Distance can be defined as a function of hole diameter

● an opening and a stiffener. Distance can be defined as a function of stiffener height or length.

● as well as checks detecting whether or not openings are centered on functional plate limits.

These checks use CATStrFunOpening in the Structure knowledge package.

Two sample checks are supplied in the design rule catalog.

You require the appropriate knowledgeware license.

No sample document is supplied.

This task shows you how to create a check to verify whether or not openings respect a minimum distance of 100mm.

Integration with ENOVIA LCAWorking with ENOVIA LCA: Optimal CATIA PLM Usability

Working with Catalogs in ENOVIA LCA


Working with ENOVIA LCA: Optimal CATIA PLM Usability

When working with ENOVIA LCA, a new mode ensures that you only create data in CATIA that can be correctly saved in ENOVIA.

ENOVIA LCA offers two different storage modes: Workpackage (Document kept - Publications Exposed) and Explode (Document not kept). Both Structure Functional Design (SFD) and Ship Structure Detail Design (SDD) have been configured to work in the Workpackage mode.

Structure Functional Design

The Structure Functional Design workbench is set up such that the user cannot create functional objects without first creating a panel system. When first entering the workbench, all other commands are therefore unavailable. The panel system has been defined as an ENOVIA LCA workpackage.

Ship Structure Detail Design

In Ship Structure Functional Design, the block scheme and paneling system have been defined as ENOVIA LCA workpackages.

The safe save mode means that certain commands (Automatic Connection, Manual Connection, Connetion Body and Mitering) are unavailable (i.e. grayed). You cannot make connections or miter cuts between two different workpackages. Recommendation: Open the paneling system in a new window and create connections within the same workpackage.

SR1 commands -> Warning dialog box !!!!

Recommended Methodology

The recommended methodology for working with ENOVIA LCA is:

● Send your ENOVIA document to CATIA.

● Work on your design in CATIA, whether from scratch or modifying an existing design.

● Save your CATIA data in ENOVIA.

To ensure seamless integration, you must have both a CATIA and ENOVIA session running.

1. In the Product Structure workbench of CATIA V5, click the Init Enovia V5 Connection... icon to establish the connection

between CATIA V5 and ENOVIA LCA.

2. In ENOVIA LCA, send your ENOVIA document to CATIA.

3. Work on your design in your CATIA V5 application.

4. In the Product Structure workbench of CATIA V5, click the Save Data in ENOVIA V5 Server... icon to save your CATIA

data in ENOVIA.

The Save in ENOVIA V5 dialog box appears showing objects to be saved and set to the correct save mode and save options.

The dialog box below shows Structure Functional Design objects.

5. Simply click OK in the dialog box.


For more information, see the CATIA / ENOVIA Interoperability User's Guide.

In ENOVIA LCA, the SFD panel system, and SDD block scheme and paneling system are each saved as one document.


Working with Catalogs in ENOVIA LCAProject resource catalogs of resolved (available) sections and structure materials can be stored in ENOVIA and accessed from design commands.

Resolved Sections Catalog 1. In CATIA, make up a list of sections you will need for the current project.

Note: Save the list of sections in a resolved sections folder you manage as a project resource.

2. Create a catalog containing these sections.

For information, see Using Catalogs in the Infrastructure User's Guide 3. Save both the catalog and the sections in ENOVIA LCA.

For information on sending documents to ENOVIA LCA, see the CATIA / ENOVIA Interoperability User's Guide.

4. Update the project resource management file to reference the catalog and sections you have just stored in ENOVIA.

Notes:

● Specify EnoviaV5 as the driver

● Do not specify the catalog extension

● Leave the resolved sections path blank.

<Resource Name="StructureSectionsCatalog" Description="Structure Sections Catalog"> <ID Type="Catia" Driver="EnoviaV5" Location="SectionsCatalog"/></Resource>

<Resource Name="StructureSectionsPath" Description="Structure Sections Path"><ID Type="Path" Driver="EnoviaV5" Location="" Access="RW"/></Resource>

5. Work on your design in CATIA V5.

Note: Sections referenced are those stored in ENOVIA and not those saved locally in the resolved sections folder.

6. Send your document to ENOVIA.

Structure Materials Catalog 1. Load the structure materials catalog into CATIA V5. 2. Save the catalog in ENOVIA LCA.

For information on sending documents to ENOVIA LCA, see the CATIA / ENOVIA Interoperability User's Guide.

3. Update the project resource management file to reference the catalog.

Notes:

● Specify EnoviaV5 as the driver

● Do not specify the catalog extension

<Resource Name="StructureMaterialsCatalog" Description="Structure Materials Catalog"> <ID Type="Catia" Driver="EnoviaV5" Location="StructureMaterials"/></Resource>

❍ The Catalogs tab lets you identify the path to the resolved sections folder.

❍ The Design tab lets you define default colors and a default material-grade combination.

4. Set options in these tabs according to your needs.

5. Click OK in the Options dialog box when done.


Catalog SettingsThe Catalogs tab contains only one category of options: Resolved Sections Folder.

Resolved Sections Folder

PathEnter the path of the folder in which the list of available sections will be stored, for example e:\Section, or use [...] to locate the folder of interest.

This directory will contain resolved user-defined sections which are stored here directly as well as any standard or user-defined catalog sections selected via the Section icon or the Other section... option. It is recommended that you identify an empty directory.

By default, this option is left blank.

Note: Other catalogs, such as the standard section catalog, thickness table and opening catalog are project resources and can be browsed via the Project Management command (Tools menu).


Design SettingsThe Design tab contains the following categories of options:

● Color

● Material

Color

Use the color chooser to define the default color for functional stiffeners, functional plates, functional pillars and the selected support surface.

By default, colors are as shown above.

Material

Select the default material-grade combination for functional stiffeners, functional plates and functional pillars from the corresponding list.

This is the combination proposed when creating functional plates, insert plates, stiffeners, twisted profiles and pillars if no default value has been specified in the Feature dictionary.

By default, the material-grade combination is Steel A100.


Glossary

Aanchor point Corresponds to the point at which a section is

anchored along the trace.

attribute Characteristics of an object such as thickness, material, section. Also referred to as properties.

Cconceptual molded form A conceptual surface defined in the Structure Conceptual Design

workbench.

Ffeature dictionary The document in which object classes are managed.frame One of the transverse members that make up the riblike part of the

skeleton of a ship. Frames act as stiffeners.functional molded form A functional surface derived from a conceptual surface. You can define

more than one functional molded form from a conceptual surfacefunctional plate A structural part.

Iinsert plate A special type of functional plate.

Oobject class The classification or type of an object. Classes are arranged in a

hierarchical structure.opening A structural feature. May be specialized as access holes, general

arrangement holes, lightening holes or penetration holes depending on their function. Geometric shapes of structural openings can be defined using the sketcher or selected from a catalog.

Ppanel system A functional structural assembly combining plate and stiffener parts, and

optionally openings. Panel systems are treated as a whole in downstream design and/or production processes.


pillar A vertical member or column which provides support to a deck.property Characteristics of an object such as thickness, material, section. Also

referred to as attributes.

Ssection A sketch that serves to describe the shape representation of a structural

shape. The sketch is contained in a separate section document. When creating structural shapes, the shape is linked associatively to the

section document. All shapes using the same section share the same sketch. If the sketch is modified, all shapes linked to the section document are automatically updated.

section orientation Defines how the section is oriented around its anchor point

shell expansion Used to assist the creation of stiffeners and plates on the hull.

The curved hull is laid flat in a CATDrawing and stiffener and plate traces can be sketched, then imported into the 3D document.

stiffener A straight structural shape used to stiffen panel systems.stiffener system A system of structural shapes used to stiffen panel systems. Includes

functional stiffeners, twisted stiffeners and pillars.straking Process of breaking functional molded form panels down into plate

lengths and widths.

Ttrace A curve or line lying on a surface that is used to define the path a

stiffener will follow. In the case of plate traces, curves or lines that cross each other to form a grid.

twisted stiffener A curved structural shape used to stiffen the hull in particular.
