4.1.2.6.3 Material Profile Set Usage

When the occurrence has an associated IfcObjectType, that object type may define the material profile set (no usage). In this scenario, all occurrences of that type must use that profile set.

A beam type may define a material profile. A beam of that beam type will then have a geometry correlating to that profile, extruded along an axis.

The usage may parametrically define an 'Axis' reference curve, an offset, alignment, and extent of the profile to extend along the axis.

Profiles will typically be parametrically defined and named according to a standard, and have material properties that assist in usecases such as structural simulations.

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 table below shows a recommended list of general usage patterns that users may adopt.
