4.8.1.11 Profile Geometry

Elements filling an opening provide a 'Profile' representation describing the shape of the cutout. Examples of such elements include doors and windows.

The representation identifier of the profile representation is:

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.
