attic remodel

[draitp]

Thanks for the rapid replies. I did learn quickly that "attic" is not a helpful term. I only used it to get the brick finish on the chimney in the area between the non-existant ceiling and the roof. I did construct the model with two floors with the stairs extending from 1 to 2. I did click on auto stairwell. That's when the odd railings appeared and the dormers got squirrly. Also, when I get to this point, I can't back up. The dormers still don't fit and I have to start over on their cocnstruction.

That brings up another problem. I added a brick wall finish to the chimney on floor 2 and then went to the attic to added brickwork there. However there is a gap between the two (see pic) that I can't eliminate. And is there a better way to make a chimney than constructing a small room with 4 walls?
