Changed#

  • [CAD Converter] Included core extension and backend converter versions in output creator metadata.

  • [CAD Converter] Conversion arguments and Parameters are logged at the start of conversion.

  • [DGN Converter] A transform is applied to Mesh prims to place them at the centroid of their combined Graphics Elements.

  • [HOOPS Converter] The Prototypes Prim is a Scope rather than having an undefined type name.

  • [HOOPS Converter] BIM relationships are translated to UsdRelationships for IFC models.

  • [JT Converter] Updated to JT Toolkit version 11.7.1.

  • [JT Converter] Empty UsdGeomPointBased Prims are not defined if no points were generated.

  • [JT Converter] Line strips where the end vertex of one line is collocated with the first vertex of the next will be joined together.

  • [JT Converter] Constant display color primvars based on Material parameters are only authored in the absence of per vertex colors.

  • [JT Converter] Per vertex normals are translated for UsdGeomBasisCurves and UsdGeomPoints prims.

  • [JT Converter] Per vertex colors are translated for UsdGeomMesh, UsdGeomBasisCurves and UsdGeomPoints prims.

  • [JT Converter] Constant widths are translated for UsdGeomBasisCurves prims.

Fixed#

  • [CAD Converter] Conversion failures are correctly handled and logged.

  • [HOOPS Converter] Addressed memory leak vulnerabilities.

  • [HOOPS Converter] Fixed conversion failures due to UnicodeDecodeError on Linux.

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.
