Changed#

  • [CAD Converter] Material information is now authored as USD attributes, allowing materials to be queried through USD metadata.

  • [CAD Converter] Updated the DGN Converter UI to expose all available converter options, including support for string list and JSON list option types, enabling configuration through the UI.

  • [CAD Converter] Added compositionStyle parameter to control how CAD assembly sub-components are composed in USD output: single monolithic file (default), separate files via USD References, or separate files via USD Payloads.

  • [DGN Converter] Updated to ODA Kernel and Drawings SDKs 27.3.

  • [DGN Converter] Default Parameters.surfaceTolerance changed from 0.2 to 0.02 (meters).

  • [HOOPS Converter] Updated to HOOPS Exchange SDK 2026.3.0.

  • [HOOPS Converter] Extended compositionStyle parameter to support additional CAD formats (SolidWorks, Revit, NX, CATIA).

  • [HOOPS Converter] Added parameters for authoring physical properties (surface area, volume, gravity centers, matrices of inertia) on converted USD prims: - convertPhysicsData — Enable/disable physical properties authoring (default: false). - physicsAccuracyLevel — Accuracy level for physical property computation, from 0.0 (coarse) to 1.0 (fine) (default: 0.99). - physicsUseGeometryOnRiBRep — Use geometry instead of topology for BRep physical property computation (default: false).

  • [JT Converter] Updated to JT Open Toolkit 12.0.

Fixed#

  • [CAD Converter] Fixed documentation anchor warnings.

  • [DGN Converter] Parameters.surfaceTolerance is now interpreted in meters and converted to DGN master units internally (divided by stage metersPerUnit).

  • [DGN Converter] Fixed color resolution for by cell or by level elements and scene graph instanced SharedCellReferences.

  • 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.
