The Shop Floor Format Problem
Without 3D CAD Batch Converter
- Designer sends IGES, your CAM software needs STEP
- Units are in inches but your machine runs metric
- Axis orientation is wrong — Y-up instead of Z-up
- Converting one file at a time for each job
With 3D CAD Batch Converter
- Batch convert entire job folders instantly
- Auto-convert mm ↔ inches ↔ meters during import
- Fix Y-up/Z-up and left/right-hand coordinate systems
- Save presets per machine — reuse every time
Built for Manufacturing Workflows
STEP/IGES to STL, DXF, OBJ, and back. Extract 2D profiles from 3D solids for waterjet and laser cutting.
Convert between mm, cm, inches, meters, and feet. A single wrong unit can ruin a $50,000 CNC run — catch it automatically.
Fix axis orientation mismatches (Y-up to Z-up, left-hand to right-hand). Align models to your machine's coordinate system.
Process entire job folders. CLI and watched-folder mode for automated manufacturing pipelines.
