Exterior material showing on interior wall of room with vaulted ceiling

[David J. Potter]

Since you have Pro you can use the Pony Wall and then manually SHAPE the two resulting Wall Poly Lines to suit your purpose. You cannot get what you want merely by settings and choices, after you have the Pony Wall halves in place (one for the exterior and one half for the interior) you must then manually manipulate the Wall Poly Lines to fit the angles of the roof, inside and out. It requires a little study of pony walls in the reference manual and then applied practice of what you read but can be done, once the process is understood.
