Title: Suitable for only the simplest designs
Review: If you want to design and build a box with a simple A-frame roof, then this tool is for you. For any modern design with multiple roof lines, gable walls, bonus rooms, etc. it just doesn't work. Also, the window library is not very good and there are no way to build your own windows, i.e. put an eliptical transom over a window, etc.
