Arclet-CAD (07egta)MCADConfidence: Medium

Arclet's exports could silently drop geometry, so the PR rejects bad facets and adds round-trip tests for STEP, IGES, STL, OBJ and 3MF. In SolidCraft 0.27.1, a user's OBJ came back faceted after import and export, with the vertex normals lost, while the same file looked smooth in CAD Assistant.
