==Material Profile Set==

[[File:Profileset.svg|thumb|right|An example of a material profile set with multiple profiles]]

A profile set is made up of individual material profiles. A profile is a shape or outline of a typical cross section which is extruded along an axis. Typically, this is used for structural analysis, where a material profile helps define its mechanical properties.

Typically, only a single profile would be defined in a profile set. This profile would also typically be parameterised, such as a circular proflie, rectangular profile, or I-shaped profile. This would then be used for a duct, pipe, or a beam.

It is also possible, though less common, to define multiple profiles in a profile set. This results in a composite profile, which is useful for describing complex shapes.
