SolidCraft (tangency-labs)MCADConfidence: Medium

After a shell on a tapered, filleted box, four inner corner fillet edges miss their surface by up to 0.0198 mm. SolidCraft shows the body and re-imports it without complaint; FreeCAD 1.1.4, used as an outside reader, flags the four faces as invalid.
