I've been trying to build a shed roof and watched the training video on it. (I was working with an old version of Home Designer, but upgraded it just now.) When I click on "build roof" I only have a very few specifications to choose from, but the video shows a whole slew of them. What is wrong with my settings, and how do I get them back to match the video? Is the video using a more expensive version with more "bells and whistles?"
