fascat

Fascat converts STEP, IGES, and OpenCASCADE BREP assets into realtime-ready OpenUSD, glTF, OBJ, STL, and FBX assets while preserving hierarchy, materials, transforms, and repeated parts where the source format exposes them.

Why fascat

• Focused — V1 supports CAD import through STEP, IGES, and native BREP, with OpenUSD, glTF, OBJ, STL, or FBX output
• Scriptable — command results can be emitted as JSON for pipeline use
• Inspectable — conversion reports expose options, warnings, timings, and mesh statistics
• Conservative — lossy operations are explicit and controlled by profiles or flags
