prefabricated wall components

[Dave Brach]

I want to create a series of library part that consists of a section of wall with a window and/or doors in the wall. The wall will have a complex profile and I want the wall to retain the properties of a wall, and the window to retain the properties of a window. They don’t need to be library parts per se, but something that can be accessed through a menu-type structure. This is for a pre-fabricated building system where the windows and doors are already installed in the chunks of 2’, 4’, 6’, and 8’ sections of wall. How do I do this?
