I jumped the gun and replyed to your design and didnt read the post before it . I shouldnt have asked you to add the rest of the room, its not a big deal. I do however need the columns if you can figure out a way to add them. You can see the 2 on the back wall in the picture, and there are also 2 on each side wall.
You can email the files to me direct at firstname.lastname@example.org
Thanks so much!
