Computes the inner length of curve loops.

Computes the outer length of curve loops.

Creates an extruded solid from a collection of curve loops and a thickness.

Creates extruded solid from extrusion data.

Creates an extrusion with potential clipping from a list of solids corresponding to an element.

Creates an IfcProfileDef for a swept area.

Creates an extruded solid with composite profile from a collection of regions and a thickness.

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.
