Changed#

  • [CAD Converter] Renamed Scene Optimizer options to sceneOp* camelCase names; legacy Hungarian keys remain deprecated aliases.

  • [CAD Converter] Behaviour change: Scene Optimizer UV generation (sceneOpGenerateUVs, formerly bOptimize) now defaults to false to avoid USD scene bloat from unused UVs. New conversions with default parameters no longer generate UVs; set sceneOpGenerateUVs to true to restore the previous default behaviour.

  • [DGN Converter] Exposed surfaceToleranceUnit through configuration, command-line, and import-dialog workflows.

  • [DGN Converter] Added a combined Surface Tolerance and unit UI using the ODA Drawings DGN unit constants plus arbitrary Custom scales, with independent value and unit selection.

  • [HOOPS Converter] Skip authoring fully-opaque opacity to reduce USD scene bloat.

Fixed#

  • [DGN Converter] Keep hidden and visible elements separate when merging geometries.
