Entity definition

IfcSectionProperties defines the cross section properties for a single longitudinal piece of a cross section. It is a special-purpose helper class for IfcSectionReinforcementProperties.

HISTORY  New entity in IFC2x2.

The section piece may be either uniform or tapered. In the latter case an end profile should also be provided. The start and end profiles are assumed to be of the same profile type. Generally only rectangular or circular cross section profiles are assumed to be used.
