Tool for deleting all material information from the model.
This tool only deletes the material information defined by the IFC material system. If the model has property set properties that contain information related to materials, you must exclude those properties to get rid of such material information.
Deleting all material information can have unwanted side effects. For walls the position of the wall can be dependent on t he material layers and deleting the material layers can shift the geometry of the wall. In some cases material information is also mandatory according to the IFC schema (enforced through Where rules). Some applications may complain about this. Future developments of this tool (or similar other functionality) will take these issues into account.
