CreateExtrudedSolidFromExtrusionData 

Creates extruded solid from extrusion data.
 

CreateExtrusionWithClipping

CreateSweptArea 

Creates an IfcProfileDef for a swept area.
 

PlanarFaceClipPlaneComparer 

Face planes comparer
remarks This is intended to sort already known unique PlanarFaces by FaceNormal, so that we can control the order that clip planes are created in. If we do have multiple faces with the same normal, use Origin as a tie-breaker. If we do have mutliple faces with the same normal and origin, the user will have to check for this condition.
