IfcProfileResource

The schema IfcProfileResource defines the two dimensional profiles or cross sections, used to define geometric shape representations. Profile definitions are applied to:

NOTE: Profile definitions are not subtypes of geometric representation item and can not be used directly to geometrically represent an object.

Profiles can be used to either define a curve or an area. In case of a curve, only the boundary is in the domain of the profile definition, in case of an area the boundary and the inside is in the domain of the profile definition. A curve can be used for

and an area can be used for

NOTE: The use of profile definitions is the preferred way to define prismatic shapes to represent products.

The profile definition (IfcProfileDef) can be instantiated by the various subtypes. There are four different groups of profile definitions:

HISTORY: New schema in IFC 2x, definitions (which had been enhanced in IFC 2x) were part of the IfcGeometryResource in earlier IFC Releases.
