Changed#

Fixed#

  • [OMPE-31988] Skipped conversion of DGN elements containing invalid mesh vertices to prevent processing errors.

  • [OMPE-31993] Optimized JT converter performance when handling large face sets, reducing processing overhead.

Breaking Changes#

  • This CAD Converter release requires Kit 106.x.

  • The parent CAD Converter extension is now at version 202.2.1, while its dependent backend extensions are at version 50x.x.x.

  • Users only need to enable and update the parent CAD Converter extension, omni.kit.converter.cad, which will automatically activate the necessary backend extensions.

    • If an older version is installed, please follow the instructions provided here to switch to a different CAD Converter version.

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 up to 32 GB of memory available for conversion.

  • Most properties are not converted to USD attributes. PMI and BIM data is not converted for the following formats: .dgn, .jt, .fbx, .obj, .gltf, .glb, .ply, .lxo, .md5, .e57, and .pts.
