On a Revit 2024 project, rvt-ifc wrote 73 AR_DOR_ doors as IfcOpeningElement and the other 361 as IfcDoor. The converter decided "this type only cuts its host" from a byte scan that missed a geometry-material map, so a door with unread materials became a hole in the wall. The PR calls it "a standing misread rather than a regression," unchanged since v0.6.1. Fix reads the type's native map and labels the case "materials not read" instead of "draws no geometry."
