Valve with handwheel (STEP → GLB), rendered from the converted file — **STEP → GLB**Valve with handwheel: 8.7 MB STEP → 13.9 MB GLB at Standard quality, 171,790 triangles, 7.0 s (Ryzen 9 3900X).

The 3D Asset Pipeline Problem

Without 3D CAD Converter

Industrial CAD models are too heavy for real-time rendering
Manual conversion per asset in Blender or online tools
No batch pipeline — one file at a time
Tessellation settings aren't optimized for game LODs

With 3D CAD Converter

STEP/IGES to glTF/GLB with optimized polygon count
Batch convert entire asset folders in one command
CLI integration for CI/CD and build pipelines
Tessellation presets from Draft (game LOD) to Ultra (hero assets)

Built for Real-Time 3D Pipelines

glTF/GLB Export

Convert any CAD format to glTF 2.0 or binary GLB. The standard for web 3D, AR/VR, and modern game engines.

Polygon Control

Fine-tune tessellation from Draft (low-poly game LODs) to Ultra (hero assets). Control chord deviation and angular deflection.

FBX, OBJ, DAE

Also supports FBX for Unity/Unreal, OBJ for legacy engines, and Collada (DAE) for interchange.

CLI Pipeline

Full command-line interface. Integrate into build scripts, CI/CD, or watched-folder pipelines. JSON output for automation.

Automate with the CLI

# Convert STEP to glTF with fine tessellation

cadconvert convert model.step -f gltf --quality fine
# Batch convert a folder to GLB

cadconvert batch ./cad-assets -f glb --quality standard
# Watch folder for incoming CAD files

cadconvert watch ./incoming -f gltf --repair
