Command line utility to convert STL files to STEP (ISO 10303-21) files. The translation is a direct triangle-to-triangle conversion with tolerance-based edge merging. stltostp generates CAD-interoperable STEP files without depending on third-party libraries like OpenCASCADE or FreeCAD.
Features:
- ✅ STL to STEP conversion (ASCII and binary STL support)
- ✅ AP214 ISO 10303-214 standard compliance for CAD tool interoperability
- ✅ Automatic edge merging with configurable tolerance
- ✅ No external CAD library dependencies
