Penetration Management Setup

 This task explains the setup process for defining a penetration cutout sketch, and identifies some of the processes involved. Penetration management uses design rules that are Knowledgeware-based. To modify the sample rules provided with this application, or to create new design rules, you must know how to use Knowledgeware. Read the documentation for that product to get more information. In addition, you must incorporate certain data particular to this application when creating new rules. That is explained below. You may also need to refer to ENOVIA-LCA documentation for ENOVIA-specific tasks.

If the Penetration Management Tools toolbar is not displayed then click View - Toolbars and select it.
Penetration management refers to the process of routing a pipe or a duct, as an example, through a structure. If you are working with a ship, for instance, you may need to create penetrations through bulkheads, move objects, or reroute your pipe or duct, in order to do so. The penetration management function works within the ENOVIA environment only. You must be in the ENOVIA Product Structure.

 

 1. The Penetration Management function uses the following:
Penetration Openings Catalog (Openings.catalog)
Penetration Shapes Catalog (PenShapes.catalog)
Penetration Cutout Rules (PenetrationCutoutRules.CATProduct)

These files are located in ...intel_a\startup\components

Set your Tools Options to reflect the location and names of these files.

From the menu bar, select Tools - Options - Digital Mockup - DMU Space Analysis

Select the Penetration tab, and set the location and file information.
2. The outlines of openings are dependent on the shapes defined in the Penetration Shapes catalog. You cannot define an outline in the design rules that does not have a corresponding shape in the catalog. Shapes defined in the sample catalog are: oblong, round, rectangular, square and rectangular radius corner. You can change the values of the parameters of the shapes in the catalog, and you can add new shapes to it. You can remove, replace or rename the sample shapes.

Each shape is a parametric part created with the Part Design product, and is stored in the same directory as the catalog. The oblong shape document, for instance, is OblongShape.CATPart. See Part Design documentation for information about using that product.

To add a shape you must create it with Part Design and store it in the catalog using standard catalog building procedures. See Creating a Catalog and associated tasks in the Catalog section to learn more about creating and modifying catalogs. These are standard parametric parts and there are no special requirements for building them. When building new shapes you should note that the description name you use in the catalog is the name that will display when you are creating a cutout sketch.
3. Most penetration cutout designing will be done using the design rules, although you have the capability of manually defining cutouts, as explained later in this section. The rules work with the shapes in the catalog to determine the final size of the opening. You can add various parameters to the rules using Knowledgeware. However, the function of the sample rules supplied with this application is mainly to determine the shape of the outline, based on the shapes available in the catalog; and calculate the size of the opening. The cutout size is calculated from the sizes of the objects involved in the penetration, with the addition of required clearances.
4. Design rules can be modified, and new ones created, using Knowledgeware. However, there are certain points you must incorporate in a design rule for it to work correctly with this function. The following information is meant for an administrator, or whoever is creating the design rule. You can see examples in the sample rule, which is reproduced below. A penetration cutout rule should:
  • Create a variable (defCutout) to hold the DefinePenetrationCutoutShape object, which will communicate the cutout definition to the penetration management command.
  • Calculate the size of the cutout, using attributes of the penetrating and penetrated objects.
  • The NewDefinePenetrationCutoutShape function creates the temporary object that holds the cutout definition. The penetrating object (p1) and penetrated object (p2) are specified.
  • The ShapeName attribute selects the parametric part that defines the shape.
  • The SkewTolerance attribute sets the allowed SkewTolerance for the penetration.
  • The SetAttributeDimension function (or another SetAttributeXXX function) specifies a parameter name in the parametric part, and its value. This function is used repeatedly to set each parameter of the parametric part.

A sample rule is reproduced below:
5. The CATIA Domain Discipline Table is used to associate a CATIA model domain to an industrial discipline identified in your company.

You are provided with a sample table located in:

...intel_a\reffiles\DomainDiscipMappingTable.xml

This table is often sufficient for your requirements, but you can modify it to change the discipline names or add a CATIA model domain. Use any text editor to modify the DomainDiscipMappingTable.xml file. After editing, save the file in the reffiles directory.

The following is a sample of the file format:

The ENOVIA discipline names are also user-defined, and must correspond to the discipline names in the ENOVIA Penetration Discipline Table located on the ENOVIA code server in ...\(platform)\reffiles\PenetrationDisciplines.xml. (The paths for all platforms are identical with the exception of the platform identifier. For example, on AIX the platform identifier is .../aix_a/reffiles.)

The ENOVIA discipline names are used in ENOVIA to look up the penetration discipline code. The penetration discipline code is used in the Penetration ID, and for assigning workflow activities in a Penetration workflow process.
