I am trying to create a family of precast concrete panels , 22' wide x14'10" high. The pic is attached. What is the best way to create it. I am using the curtain wall template and changing the grids size to 22' x 14'10" and placing the family. It would also be great to know the right way to show glass ( I have not been able to bring in a window into this family) as well as the structure for the precast panels. The precast panels are 2" in depth with an airgap of 2" and then 4" structural tubing behind it.
