4.2.6.3 Material Profile Set Usage

A material profile set may be defined on an object type. In this scenario, all occurrences of that type must use this profile set to parametrically define their geometry.

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