Thanks for the suggestion Grechief - I found where to check that box - and did so, but honestly it had no effect which makes me believe I'm going about this incorrectly. Many, if not most common houses have a simple porch with a simple, slanted roof over them that is attached to the house wall and supported on the other side by columns of some sort - usually 4x4's or 6x6's. For such a simple thing, I'm finding it very difficult to figure out how to do it simply. I've been cautioned about taking up everyone's time so, I'll keep experimenting. But, thanks for reading my problem and offering....
