[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.
