Hello, I've looked at suggestions made for creating windows in canted walls and I'm having trouble getting the correct results.  
Originally, I used a canted wall and found that it's reference wall's windows were only appearing as openings..  So then I copied the reference wall and saved it as a GDL, went into the 3d script and added the cant angle to ROTX.  There are two prompts for ROTX, so I tried adding the angle to both.   What I end up with is a perpendicular wall w/ a canted window....exactly the opposite problem of what I started out with, and still not right.  Any advice for me?  I'm new to this GDL stuff... perhaps I'm modifying the wrong line in the script?
