A good one to use is http://sketchup.google.com/ you can use it to totaly customise your shop … there are even model tools/machines you can download so you dont have to draw up your own and move around and set where ever you want … another good thing is you can use it for so much more … like designing all your woodworking projects ….. a big bonus is you can print it out and follow your own sketch in the shop
