Only the following geometric representation items are allowed as an 'Axis' shape representation of IfcWall, and IfcWallStandardCase.
- linear segment as IfcPolyline with two points, or as IfcTrimmedCurve with BasisCurve being an IfcLine.
- circular arc segment as IfcTrimmedCurve with BasisCurve being an IfcCircle.
- An 'Axis' shape representation is mandatory IfcWallStandardCase and optional for IfcWall.
- [added 16-07-2011] An 'Axis' shape representation is also optional for IfcBeam, IfcColumn, IfcMember. The requirements shown above do not apply for these elements.
