4.8.1.11.1 Profile 3D Geometry

The Profile 3D Geometry is the standard representation of the outer profile for elements filling an opening. Examples of such elements include doors and windows. In the case of doors and windows the profile geometry is used to apply the parametric definition of lining and panel dimensions to the profile.

The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

The following diagram shows the generic classes and relationships used when applying this concept. In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the tables below shows a recommended list of general usage patterns that users may adopt.
