Axis System, Layer, Layer Filter and Selection Set

CATIA V5 Reader exports:

• Axis System information including name and current status.
• Layer and Layer Filter information including name, current status, and entities in the layer, and layers in a layer filter. If the source CATIA V5 file contains layers having a layer value as NONE, then the layer value for that particular layer is set to 1023 in the resultant file.
• Selection Sets information including name, current status, and entities in the Selection Set.

Parameters

For the InterOp ACIS product line, the Connect interface supports the translation of parameters excluding CATIA V5 feature defining parameters. These are commonly known as "part notes" (Geometrical Set containing parameters). Support for parameters is available only when the TranslateAttributes option is set to True. The following figure shows an example of supported top-level parameters. Limitations Only parameters of non-ordered Geometrical Set are supported. If a parameter is present inside multi levels of a feature tree, InterOp creates a corresponding note object at the top level only. Formulae are not supported.

Name Attribute Transfer from CATIA V5 to ACIS

While translating solids from a CATIA V5 file to ACIS, the value of name attribute depends on the type of solid being translated along with certain option settings. The various types of solids from CATIA V5 and the corresponding value of a name attribute in ACIS is discussed below.

Part with Single Lump For a part with a single lump in a CATIA V5 file, as shown in the next figure, the name of the translated Solid in ACIS is "V5_Part|PartBody|EdgeFillet.1"

Part with Multiple Lumps InterOp translates each lump from a CATIA V5 file as a separate solid in ACIS. The next figure illustrates a CATIA V5 part with multiple lumps. The names of the translated solids in ACIS become: Solid body : "V5_Part|PartBody|Pad.2" Solid body : "V5_Part|PartBody|Pad.3"

Sketch in Part Body

The translation of curves and points present in a Sketch depend on the value of these options:

• TranslateFreeCurves
• TranslateFreePoints

Curves All the connected curves in the Sketch as shown by cyan lines in the next figure are translated as One Wire Body. The individual segments become members of this wire body. The name of this wire body becomes: "V5_Part|PartBody|Sketch.1"

Free Points

All the free points, illustrated as a cross in red color in the above Sketch, are to be translated as independent vertices. The names of these points become:

• Point #1: "V5_Part|PartBody|Sketch.1"
• Point #2: "V5_Part|PartBody|Sketch.1"
• Point #3: "V5_Part|PartBody|Sketch.1"
• Point #4: "V5_Part|PartBody|Sketch.1"

Sketch in Geometrical Set

The translation of curves and points present in a Sketch depend on the setting of these options:

• TranslateFreeCurves
• TranslateFreePoints

Curves All the connected curves in the Sketch as shown by cyan lines in the next figure are to be translated as one wire body. The individual segments become members of this wire body. The name of this wire body becomes: "GeomSet|Geometrical Set.1|Sketch.1"

Free Points

All the free points, illustrated as a cross in red color in the above Sketch, are to be translated as an independent vertex. The names of these points become:

• Point #1: "GeomSet|GeometricalSet.1|Sketch.1"
• Point #2: "GeomSet|GeometricalSet.1|Sketch.1"

Geometrical Set

The translation of free curves and free points in geometrical sets depend on the value of these options:

• TranslateFreeCurves
• TranslateFreePoints

Surfaces The surfaces in the geometrical set shown in green color in the next figure are to have the following name in ACIS: "GeomSet|Geometrical Set.1|Extrude.1"

Free Curves

The free curve in the geometrical set shown in cyan color in the previous figure is to have the following name in ACIS:

• "GeomSet|Geometrical Set.1|Circle.1"

Free Points The free points in the geometrical set illustrated as a cross in red color in the next figure, are to have the following names in ACIS: "GeomSet|Geometrical Set.1|Point.2" "GeomSet|Geometrical Set.1|Point.3"

Axis Systems When a part is created with the "Enable Hybrid Design" option as shown in the next figure, the name of the Axis system becomes: "V5_Part_AxisSytem_1.CATPart|PartBody|Axis System.1"
When a part is created with the "Enable Hybrid Design" option off as shown in the next figure, the name of the Axis system becomes: "GeomSet|Axis Systems|Axis System.1"

Assembly

An assembly might contain parts or assemblies. Consider a scenario where we have a CATIA V5 assembly containing two parts. The following figures show the two parts of a CATIA V5 assembly:

Assembly Case 1

Case 1 This case is an assembly [Product1.CATProduct] containing one instance each of these parts. Product1 contains Part1 and Part2 as shown in the next figure: For entities in Part1, the following names are to be attached: Product1|Part1.1#Part1;Part1|PartBody|EdgeFillet.1 Product1|Part1.1#Part1;Part1|Geometrical Set.1|Sketch.2 Product1|Part1.1#Part1;Part1|Geometrical Set.1|Extrude.1 For entities in Part2, following names are to be attached: Product1|Part2.1#Part2;Part2|PartBody|EdgeFillet.2 Product1|Part2.1#Part2;Part2|Geometrical Set.1|Sketch.2 Product1|Part2.1#Part2;Part2|Geometrical Set.1|Extrude.1

Assembly Case 2

Case 2 This case is an assembly [Product2.CATProduct] containing two instances of Part1 and one instance of Part2. Product2 contains Part1 and Part2. Part1 contains an instance of assembly, Instance1. Part2 contains two assemblies: Instance1 and Instance2. The following figure shows Product2: For entities in Part1 - Instance 1, the following names are to be attached: Product2|Part1.1#Part1;Part1|Geometrical Set.1|Extrude.1 Product2|Part1.1#Part1;Part1|Geometrical Set.1|Sketch.2 Product2|Part1.1#Part1;Part1|PartBody|EdgeFillet.1 For entities in Part2 - Instance 1, the following names are to be attached: Product2|Part2.1#Part2;Part2|Geometrical Set.1|Extrude.1 Product2|Part2.1#Part2;Part2|Geometrical Set.1|Sketch.2 Product2|Part2.1#Part2;Part2|PartBody|EdgeFillet.2 For entities in Part1 - Instance 2, the following names are to be attached: Product2|Part1.2#Part1;Part1|Geometrical Set.1|Extrude.1 Product2|Part1.2#Part1;Part1|Geometrical Set.1|Sketch.2 Product2|Part1.2#Part1;Part1|PartBody|EdgeFillet.1

Assembly Case 3

Case 3 This case is an assembly containing one part [Part1.CATPart] and another assembly containing an instance each of Part1 and Part2. The following figure shows the structure of the assembly: For entities in Part1, the following names are to be attached: TopProduct|Part1.1#Part1;Part1|Geometrical Set.1|Extrude.1 TopProduct|Part1.1#Part1;Part1|Geometrical Set.1|Sketch.2 TopProduct|Part1.1#Part1;Part1|PartBody|EdgeFillet.1 For entities in sub-assembly Product1, the following names are to be attached: For Part1 in sub-assembly Product1: TopProduct|Product1.1#Product1|Part1.1#Part1;Part1|Geometrical Set.1|Extrude.1 TopProductProduct1.1#Product1|Part1.1#Part1;Part1|Geometrical Set.1|Sketch.2 TopProduct|Product1.1#Product1|Part1.1#Part1;Part1|PartBody|EdgeFillet.1 For Part2 in sub-assembly Product1: TopProduct|Product1.1#Product1|Part2.1#Part2;Part2|Geometrical Set.1|Extrude.1 TopProduct|Product1.1#Product1|Part2.1#Part2;Part2|Geometrical Set.1|Sketch.2 TopProduct|Product1.1#Product1|Part2.1#Part2;Part2|PartBody|EdgeFillet.2

Mesh

Mesh data is a collection of triangles that define a shape within the model. Connect supports translation of Mesh data from the CATIA V5 format to the ACIS format. Mesh data is called through the use of the representation named, Mesh. To support the translation of Mesh data, you need SPAXCATIAV5Mesh.dll in addition to the common DLLs listed in the section Product Specific Libraries.

Set the Representation user option to Mesh.

Visualization

The CATIA V5 Reader translates Visualization (Scenegraph) data from CGR files.

Set the Representation user option to Visualization.

Limitations

The CATIA V5 Reader has the following limitations:

• No Support for File Names with Non-ASCII Characters

The Connect CATIA V5 Reader does not support reading CATIA V5 files that are named using non-ASCII characters. CATIA V5 is based on the ISO 646 standard, which does not support multi-byte character code.

• Reading Manufacturing Information

InterOp Connect does not support reading Hole feature from assembly files.

InterOp Connect does not support reading Product Manufacturing Information that does not have a geometry owner.

• No Support for Captures from an Assembly File

The Connect CATIA V5 Reader does not support reading captures from assembly (CATProduct) files. Currently, support for captures is limited to part (CATPart) files only.

• No Support for Captures to InterOp Generic Components

The Connect CATIA V5 Reader does not support reading captures from both Parts and Assemblies to Generic.
