Note: In the table for each common option, "Y" represents availability of an option in the component and a gray box represents non-availability.

Note: If you specify an option without specifying <Component> (refer to Syntax), then this option will be ignored for those components on which this option is unavailable.

ConvertAnalyticalCurvesToSpline

• Description

This option controls the translation of analytic curves as splines. Set this option to true to enable the translation of analytic curves as splines. If you set this option to false, analytic curves are translated as they are.

• Default

false

ConvertAnalyticalSurfacesAndCurvesToSpline

• Description

This option controls the translation of analytic surfaces and curves as splines. Set this option to true to enable the translation of analytic surfaces and curves as splines. If you set this option to false, analytic surfaces and curves are translated as they are.

• Default

false

ConvertAnalyticalSurfacesToSpline

• Description

• Default

false

EnableMissingComponentsData

• Description

This option ensures that information about missing parts and missing sub-assemblies when translating to XML E-BOM is given in the destination document. For example, if the part connecting_rod_bolt_nut.prt was missed during translation, then the Missing attribute is attached to it.

<Document Name="connecting_rod_bolt_nut" Type="prt" Identifier="E:\PROEAssembly\connecting_rod_bolt_nut.prt"
FilePath="E:\PROEAssembly\87818\connecting_rod_bolt_nut.prt" SourceUuid="connecting_rod_bolt_nut.prt" Missing="True" />

If the option is not set, then no information regarding missing component will be given in the XML E-BOM file (so XML file will be written as if the missing component was not there at all in assembly).

• Default

false

EnableWideCharacter

• Description

This option controls transfer of string attributes. If you set this option to true, then all string-based attributes from the source system will be attached as Unicode into the target system. If you set this option to false, then all string-based attributes from the source system will be attached as MBCS into the target system.

• Default

false

Healing

• Description

This option controls the healing of topological data during the translation process. Set this option to true to enable healing. The input file for translation might contain bad data, which means that the translated file might possibly contain corrupted information. In addition, the geometrical or topological errors might occur during the translation process. To ensure precise and valid translation, Connect provides this option for repairing and healing the translated files. Repairing involves checking the translated file for corrupted data and fixing the invalid data. Healing corrects the differences in precision of source and entities.

• Default

true

Operations Performed

The repairing process can be categorized as follows:

• Tolerizing of Target Entities (edges and vertices) – Tolerance (precision) of the source entity might be coarser than the target kernel tolerance. This usually results in tolerance-related errors. Edges which perfectly connect at ends in the source system might show gaps in the target, or the vertices that lie on faces may give gap errors. To repair this error, tolerizing is performed on the entities. An appropriate tolerance is computed and applied to every edge and vertex of the body.
• Healing of Entities – Healing of entities can be categorized into three types:
  • Modification of topology of body – This process involves the removal of duplicate and overlapping vertices, removal of small edges, removal of sliver faces from the body, and splitting of edges having large G1 discontinuities in their pcurves. If the target system is Parasolid, then this involves removal of small edges, and removal of sliver faces from the body.
  • Modification of geometry of body – This involves reconstruction of self-intersecting and irregular curve geometry of edges, co-edges, and surface geometry of faces, as well as the trimming and sub-setting of underlying surfaces of faces to a uv-box of a face. If the target system is Parasolid, then InterOp does not modify the geometry of the body under this option; however, the DeepHealing option does.
  • Fixing of other invalid data in the body such as loop errors.

Errors Handled

The Healing option's purpose is to resolve the following errors:

• PK_EDGE_state_bad_vertex_c
• PK_FACE_state_bad_edge_c
• PK_FACE_state_bad_vertex_c
• PK_EDGE_state_vertices_touch_c
• PK_FACE_state_self_int_c
• PK_FACE_state_bad_loops_c

Effect on Performance

The process of healing affects the performance of the translator. The two main factors are:

• Time – If healing is enabled, the total time for the translation process is increased. Hence, if you are not interested in fixing check errors, then disable healing to accelerate the translation process.
• Quality – If healing is enabled, you improve the quality of the translated model. The healing process attempts to fix all the check errors and bad input data in the model as much as possible during the process.

PartTargetDocumentType

^{* This option is applicable for ASAT only with the ACIS Reader.}

^{+ This option is applicable when translating ditto as assembly with the CATIA V4 Reader.}

^{** When PartTargetDocumentType is set to Generic, you should set the target unit as meter.}

• Description

This option controls the target document type when translating from any assembly format to XML-EBOM. By default, the part target document type is ACIS, hence the XML-EBOM Writer dumps part references as SAT files (output is XML+SAT). This option overrides the default behavior from XML+SAT to XML+X_T (or other) depending upon the option value.

For example, if PartTargetDocumentType is set to Generic, then the XML-EBOM Writer outputs to XML+X_T files.

The syntax for specifying this option is shown below. For example, to translate CATIA V5 assembly to XML-EBOM (that is, XML+X_T), you would specify the required option as follows:

EBOM.Assembly.Writer.CATIAV5.PartTargetDocumentType=Generic

Also, you may specify the option as follows:

EBOM.Assembly.Writer.*.PartTargetDocumentType=Generic

or

PartTargetDocumentType=Generic

• Default

ACIS

RecordingSession

• Description

This option specifies the session file for writing the session information. If this option is set to a session file, session information is written to the specified file. When this option is not set to any file, session recording is not performed during the translation process. For more information, refer to Session Recording.

• Default

" " (Empty string)

Representation

Refer to Connect Representations for detailed information about the representation concept in InterOp.

The following table lists the Representations supported on InterOp components:

^{* Not yet available for the Parasolid product line}

^{** Supports reading session files and ditto elements as assembly.}

• Description

This option selects the model representation to translate. Valid values for this option include BRep, Assembly, Visualization, Mesh, PMI, and Manufacturing. You can combine the two different representations using a plus (+) sign, for example, BRep+Assembly.

Note: You are advised to use the BRep+Assembly representation for the components where it is not possible to determine whether the input file contains BRep or Assembly or both type of data. For example, you should use this combination for IGES, STEP, Parasolid, and Unigraphics components.

Note: The PMI and Manufacturing representations are associated together. Hence, if you set either of these representations, both are included for translation.

• BRep – Boundary Representation. Manages topological and geometrical data.
• Assembly – Product data representation. Manages the process of how parts are assembled to define a product.
• Visualization – Manages the data (usually facets) that defines the visualization of a model.
• Mesh – Collection of triangles that define a shape within the model.
• PMI – Product Manufacturing Information. Manages text, annotations, dimensions, and tolerances.
• Manufacturing – Manufacturing Features such as Hole data.

• Default
