CAD Converter 201.0.0#

Added#

  • Added UTF-8 file handling support and Transcoding library to handle invalid prim names on conversion.

  • Added support for CATIA V6 (.3DXML).

  • Added support for Revit 2024 file types.

  • Improved error handling and logging.

  • Added support for material opacity settings and transparencies.

  • Improved CAD Conversion performance.

  • [DGN Converter] Added new Tessellation controls for Surface Tolerance to the UI and configuration for custom input. Remove presets to give users more control.

  • [DGN Converter] Added a setting to control the conversion of hidden objects.

  • [DGN Converter] Added settings to filter conversion by a list of level names.

  • [DGN Converter] Added support for DGN element type OdDgProxyGraphicsElement

  • [JT Converter] Updated the USD Stage hierarchy and prim types to follow recommended USD best practices for asset structure and scaling.

  • [JT Converter] Added curve support. Now, curve and line data sets are converted to USD basis curves for rendering.

  • [JT Converter] Enabled the use of pre-tessellated geometry data by default.

  • [CAD Converters] Updated all CAD SDKs to the latest stable versions.

  • Updated Omniverse Kit SDK to v106.0 Beta.

  • Updated CAD Converters to use the Omniverse Connect SDK API.

Fixed#

  • Resolved issues with adding scale factor to USD prims.

  • Fixed extra suffix numbers on prim names and incorrect prim naming.

  • Fixed several issues with materials and colors not converting to USD correctly.

  • Fixed several cases in JT and DGN conversions where tessellation was not reading the correct settings, causing file size poly count to be enormous.

  • Fixed several cases of some parts in an assembly not being converted for CATIA, JT, or DGN.

  • Fixed cases when DWG conversions were missing geometry.

  • Fixed reading a JT instance and conversion to USD instances.

  • Fixed crash on conversion of large CATIA product assemblies.

  • Fixed crashes related to DWG file conversion.

  • Fixed memory issues and leaks.

  • Fixed DGN Converter File where a special character fails to import.

  • Fixed the DGN Converter issue preventing the conversion of files with spaces in their filename.

  • Corrected issues found by the USD Asset Validator.

Known Limitations#

  • CAD Converter (omni.kit.converter.cad_core) and DGN Converter (omni.kit.converter.dgn_core) do not support curve or line data.

  • Some DGN geometry data is not supported and will not convert USD mesh. If you have an example of such a DGN file, please let us know so we can troubleshoot and fix any remaining issues.

  • Converting to USD can take more memory and CPU power depending on the type of data and Tessellation settings. File size is not an indicator of how fast a conversion will take or how much memory is required. In most cases we recommend a minimum of 16 GB. Complex files will need up to 32 GB of memory available for conversion.

  • PMI and BIM data is not converted.

  • Most properties are not converted to USD attributes.

We recommend converting Revit and Creo files using the Connectors instead of the CAD Converter for best results.
