What changed in each version of 3D CAD Converter, newest first.
After the 10 free conversions, nothing is blocked: STEP, IGES and BREP exports to mesh formats switch to Draft quality and each export carries a trial note (FBX excepted), while other conversions keep full geometry. VRML (.wrl) files can be imported. Fresh output files are no longer reported as being used by another process when a batch continues.
3MF files from Bambu Studio, including the production extension, open with the built-in 3MF reader instead of crashing the converter. The --angular option on the command line takes radians. A transient lock on a freshly written STL file is retried instead of failing the conversion.
