Hi Nik, We recently started using Google¹s 3-D program ³Sketchup² for our layouts. The basic program is free and fairly fast to get started with. It allows us to give prospective customers a simple perspective drawing showing how it will look. It has a shading feature that allows you to move the sun through the day to see what effect shading has. Definitely a good tool for more the less-conventional layouts like you describe. -Kelly
