SetDesigner is a tool specifically designed for aiding in the design and visualization of theatrical sets. It is not a CAD program. The laws of physics are not enforced by the program itself. Sets can be designed in SetDesigner by sizing and arranging predefined common elements of sets (for example: platforms, and flats), and defining paint schemes for these objects.
