Grid structures built out of 2D surfaces and 3D objects
This video shows how to build grid structures and mullions out of 2D surfaces and 3D objects in 3ds max. Both methods are based on the topology/ tessellation of your geometry. You can create shapes/ lines from the edges of your surface and use these lines to create your grid structure. The video also shows you how to create grid structures based on polygons in a parametric way.
