I'm trying to figure out how to create a 3D door or window that will show 4 panels that will stack to one side -- sort of like the existing 3-panel slider, but with 4 panels. Hopefully, it will be able to be resized to fit a variety of openings. The client wants to show them partially opened in the rendered model, and to show accurately how they will stack in the thick wall in plan view Any ideas? Using Architecture 2010.
