3D CAD Converter batch-converts 3D and CAD files on Windows: STEP (AP203/AP214/AP242), IGES, STL, OBJ, 3MF, glTF/GLB, FBX, PLY, DXF, DAE, X3D, VRML and more - 15+ formats in and out. Convert one file or thousands in a single run.

Built for engineers, 3D-printing users, and technical teams who receive CAD files they cannot open: convert CATIA, SolidWorks, and Inventor exports to neutral formats without vendor licenses. Everything runs locally - proprietary models never leave your machine, unlike online converters that require uploading your IP to a server.

Key features:

- Batch conversion with folder recursion - hundreds of files in one pass

- Tessellation quality presets (Draft, Standard, Fine, Ultra-Fine) with deflection control for smooth STEP-to-STL output

- Mesh repair and decimation for 3D-printing-ready output

- Unit scaling (mm/inch) and coordinate-system conversion

- Assembly support with hierarchy preservation

- 3D preview before conversion

- Command-line interface for automation and scheduled pipelines

Typical uses: preparing STEP files for 3D printing (watertight STL), converting supplier CAD packages into a common format, publishing lightweight glTF models for web/AR, migrating format archives, fixing meshes that fail slicer checks.

License: free trial, then a one-time license - no subscription (compare with CAD Exchanger at $590/year).
