Cool! I've bookmarked it and will explore working with it. I was afraid there might not be much out there. I found sites where they have floor plans for sale and show the houses they make. But that's no fun.
When I tested in my Senior Year of High School (mumble mumble years ago, oh well, 1964), the one thing that matched all of my likes and capabilities was architecture. I sometimes wish I had pursued a career in that. I can waste hours playing with that stuff.
