To Calculate Cut Planes of Spaces

If you are working with 3D freeform spaces, you can calculate their area at 2 different cut plane heights. This is useful for attics, where different heights are calculated differently.

1. Create a 3D freeform space.
2. Define the calculation cut planes of the space.
   
3. Define the display properties for the 2 calculation cut planes and the cut plane hatches.
4. Generate and apply a property set definition with automatic properties for calculation cut planes. Then create a schedule table with the calculated cut plane values.
