I'm looking to make some examples of difference roofs that I could access and change the dimensions quickly while I am doing the presentation in a customers home, so I am limited with time. I really only need the roof with the panels on. I can see the example roofs in the solar program but I don't know how to change the dimensions. Also is it possible to add you own examples to the wizard. I have watch the multi hip roof tutorial but can't seem to get to grips with where to bring the lines in and where to go back out.it would be good to have an example drawing. I have spent hours on this so far but do not seem to get anywhere. Please help
