Extruded solid: arbitrary, multiple segments

Definition

Geometry type	Extrusion	Profile	Segments	Clipped	Slanted
Extruded solid	Linear	Arbitrary	n	No	No

The concept of 'Extruded solid: arbitrary, multiple segments' defines a extruded solid (IfcAttDrivenExtrudedSolid) with more than one extruded segment using a closed arbitrary profile (IfcArbitraryProfileDef - IfcPolyline). The arbitrary profile consists only of straight segments. All segments in the solid must be extruded in the same direction but may have an offset from the extrusion path.

The solid may not be slanted. Please see the documentation of the building elements using this concept for a definition what slanted/not slanted means in the context of each building element.
