IfcArbitraryOpenProfileDef: public Ifc4::IfcProfileDef¶
The open profile IfcArbitraryOpenProfileDef defines an arbitrary two-dimensional open profile for the use within the swept surface geometry. It is given by an open boundary from with the surface can be constructed.
HISTORY New entity in IFC2x.
The Curve has to be an open curve.
Figure 308 illustrates the arbitrary open profile definition. The Curve is defined in the underlying coordinate system. The underlying coordinate system is defined by the swept surface that uses the profile definition. It is the xy plane of:
The Curve attribute defines a two dimensional open bounded curve.
