Features Highlights
Features of the VDA-FS Reader include:
- Conversion options - The translator provides an option for converting PSET, free curves, trimmed faces, free surfaces, and topological elements from VDA-FS files. Refer to TranslateTopEntities for more details.
- Support for trimmed surfaces - The translator provides an option to convert or ignore trimmed face data.
Options for VDA-FS Reader
| Option | Default | Description |
|---|---|---|
| CheckAndFixG1ThreeDCrv | true | This option checks and repairs a 3D curve for G1 continuity. |
| TranslateTopEntities | false | This option controls the translation of topological structure from a VDA file. If the VDA file has the "TOP" element and this option is set to true, the element will be translated as a solid with topological connections. If the option is false, the element will be exported as faces. |
BRep
The VDA-FS Reader component supports the BRep representation.
Limitations
The VDA-FS Reader has the following limitations:
- Data loss - Errors can occur while converting from VDA-FS to ACIS, especially when the input data is not sufficiently accurate for ACIS. During these occurrences, the translator imports as much data as possible.
