- CAD users checking models for 3D printing
- Worth noticing
- Published checks cover NIST AS1 AP203 and AP214 assemblies, 18 parts each, plus cubes, curved parts, and one IGES cube; AP242 is untested.
Field notes
The converter uses occt-import-js 0.0.23, a WebAssembly build of OpenCASCADE, and writes the STL from the triangles returned by the engine. Its published test set includes two NIST AS1 assemblies, each with 18 parts, as well as cubes, curved parts, and one IGES cube. The page explicitly says AP242 is not covered by a test file, so its stated coverage has a boundary.
