BREP_STL2STEP

First-class BREP-family STL-to-STEP CLI crate. It depends on BREP_reconstruction; its binary name is stl2step.

Install and run it with:

cargo install BREP_STL2STEP
stl2step input.stl

The command writes input.step beside input.stl, refuses to replace an existing STEP or JSON report unless --force is supplied, and writes through a temporary file before the destination is replaced. STL coordinates default to millimetres; --unit accepts mm, cm, m, micron, inch, or foot (and aliases accepted by --help).

A file holding several disjoint closed shells converts to one STEP document with one solid per shell. Recognition preserves safe analytic plane, cylinder, cone, and sphere regions in a hybrid model; full spheres, ring tori, capped cylinders, and capped cones also have direct analytic paths. Other repairable closed input can fall back to a faceted BREP unless --strict-analytic is set. Use --report-json PATH for the schema-version 2 JSON report; the command always prints a human-readable terminal report.

Exit statuses are 0 for success, 2 for usage, 3 for STL input, 4 for conversion, and 5 for output I/O. Run stl2step --help for all recognition and tolerance options.

The package is version 0.2.3 and contains only this binary. Licence: the Autodrop3d licence in LICENSE.md, shipped in the crate.
