I have just bought the program. After using the 3D walls, doors and windows.
 
After sending the files to the consultants with lower version, dimensioning walls and openings was not posible for them. They had to explode one enitity at a time or else they crash just to make file 2D.
 
I Called company but their add-on remedy did not work and only made files bigger making it hard to e-mail.
 
Suggestions anyone?
