Changed#
[CAD Converter] Update omni.usdex.libs to version ~2.1 for Kit 109.x builds.
[CAD Converter] Add priority-based converter selection to improve UI ranking (DGN files now default to DGN Converter, JT files to JT Converter in selection dropdown).
[CAD Converter] Provide more detailed logging on conversion failures.
[CAD Converter] On linux-aarch64 platforms, JT files now use the HOOPS Converter by default for conversion.
[CAD Converter] Added “Known Limitations” section for JT and CAD services extensions.
[DGN Converter] Removed internal limits on the surfaceTolerance option, allowing users to specify the full range supported by ODA. The iTessLOD parameter was removed to avoid conflicts and enable unlimited tolerance values.
Fixed#
[CAD Converter] Fixed a bug where the extensions failed to extract correct conversion result.
[CAD Converter] Fixed _unregister_importer() to unregister each registered converter delegate.
[HOOPS Converter] Apply translation to geometry Prims to place them at the centroid of the Part/Rep. Item.
[HOOPS Converter] Fixed setting of display names.
[HOOPS Converter] Fixed an issue where the top-level USD prim name was incorrectly set to the input/output filename instead of using the Product Occurrence name when defined in the native CAD file.
Known Limitations#
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 be or how much memory is required. In most cases, we recommend a minimum of 16 GB. Complex files will need a minimum of 32 GB of memory available for conversion.
PMI and BIM data is not converted for the following formats: .dgn, .jt, .fbx, .obj, .gltf, .glb, .ply, .lxo, .md5, .e57, and .pts.
