Materials

E3D Design IFC Export has support for basic IfcMaterial entities. These IfcMaterial instances have a name, but not a description or category, and cannot be given properties. They are included in the Ifc file if they are referenced by other Ifc instances. Exported elements may be associated with a single named material by setting the "Material" property of the AVEVA_EntityParameters property set to an expression that evaluates to a string.
