Thanks for the info, I have added it to my drawing, but now have another (probably easy) question. I have a 12 sided structure drawn, and stuck it over one corner of my rectangle basement drawing. There are 2 sides of it inside the rectangle, and the rest hanging out. I would like to remove the 2 sides in the rectangle, as well as the corner of the rectangle where it meets the octagon, to make it one continuous wall. I looked but couldn't find a way to remove those parts.
One last question, when I did a 3D look at what I have drawn so far, the octagon appears to be lower than the rectangle, it starts below the top of the rectangle, and finishes below the bottom. I would like them to all be on the same plane, since it is my foundation/basement.. Any thoughts as to what I might have done wrong to create this problem, and what to do to correct it?
LAST question, just thought of it, is there a good resource (book? website?) to learn this program a little better, and easier, than just hacking away at it? I don't mind experimenting, but when I have an idea in my mind, and have a lot of trouble putting it on paper (so to speak), it gets frustrating. Any suggestions would be appreciated, since the help file isn't all that user friendly or helpful, at least to me so far.
Thanks!
