Direction of extrusion relative to objects
placement. For example: (0.,0.,1.). Shall
not be perpendicular to the local z-axis.
Implementation agreements:
- Profile Type is AREA
- The first and the last of the profile definition points must be the same
- The profile is not allowed to cross itself
- Position defines the profile coordinate system origo
- Axis defines the direction of the local Z-axis
- Refdirection defines the direction of the local X-axis
- Depth of the extrusion must be greater than zero
