Thank you for responding. I played all day yesterday with the program and learned some things and found other things. Roofs have always been a struggle for me even when we were using in my Interior Design classroom. Something I found interesting is that CA assumes all houses are built as Pier and beam or with a crawl space. We just pour concrete slabs and build down here. I still haven't found how to make the concrete slab my flooring. I'll check out the links above to figure out my fireplace.
