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.
