Entity definition

An IfcSweptSurface is a surface defined by sweeping a curve. The swept surface is defined by a open or closed curve, represented by a subtype if IfcProfileDef, that is provided as a two-dimensional curve on an implicit plane, and by the sweeping operation.

The optional Position coordinate system allows for re-positioning the resulting swept surface relative to the object coordinate system.

NOTE  Definition according to ISO/CD 10303-42:1992
A swept surface is one that is constructed by sweeping a curve along another curve.
NOTE  Entity adapted from swept_surface defined in ISO 10303-42.
HISTORY  New entity in IFC2x.
IFC4 CHANGE  The attribute Position has been changed to OPTIONAL with upward compatibility for file-based exchange.
