class Ifc4::IfcUShapeProfileDef : public Ifc4::IfcParameterizedProfileDef

IfcUShapeProfileDef defines a section profile that provides the defining parameters of a U-shape (channel) section to be used by the swept area solid. Its parameters and orientation relative to the position coordinate system are according to the following illustration. The centre of the position coordinate system is in the profile’s centre of the bounding box.

HISTORY New entity in IFC2x2.

IFC2x3 CHANGE All profile origins are now in the center of the bounding box.

IFC2x4 CHANGE Type of FilletRadius and EdgeRadius relaxed to allow for zero radius. Trailing attribute CentreOfGravityInX deleted, use respective property in IfcExtendedProfileProperties instead.

Figure 327 illustrates parameters of the U-shape profile definition.

Position The parameterized profile defines its own position coordinate system. The underlying coordinate system is defined by the swept area solid that uses the profile definition. It is the xy plane of:

IfcSweptAreaSolid.Position

By using offsets of the position location, the parameterized profile can be positioned centric (using x,y offsets = 0.), or at any position relative to the profile.
