Great catch! Seems redundant information indeed.

Hi @I-Sokolov - just to confirm - you mean IfcRepresentation.RepresentationType, not IfcProduct.RepresentationType? https://standards.buildingsmart.org/IFC/RELEASE/IFC4/ADD2_TC1/HTML/link/ifcrepresentation.htm

we should discuss, since I know that some software tries to rely on it, although it is difficult to trust (as you need to check the SET of IfcRepresentation.Items anyhow).

Yes IfcRepresentation.RepresentationType (there is no IfcProduct.RepresentationType attribute) I know products relay on this... I saw crazy code in some application that tries to marriage RepresentationType and content, esecially when they conflict:)
