Hi Mick,
Thanks so much for taking the time to look at this so thoroughly. I hadn't noticed the roof planes, etc. and have been taking some time to clean up the model. The original mystery of the framing not showing up in plan view remains. I rebuilt the framing after locking in the walls that I had already edited. Lo and behold, the framing of the 2x4 wall appeared after the rebuild, but the rest did not. I am really baffled. I can open the wall
detail and there is the framing, but it doesn't show up in plan view. I guess I am going to try CA support and see what they can tell me. Again, thanks to all fellow users who replied. It's quite a learning curve for me on my first house plan.
Regards, Robert
