Thank you Eric, for having a look at this issue. I have done 21 house plans in the year I have been doing this and this is the only plan that I have had this problem. I watched your video and double checked which camera layer set I was using and I am using the 3D camera view set. The odd time the view comes up right and the second i try to select a wall or other detail while in the view, the siding disappears and other interior details are gone as well. I have checked all my default settings, everything seems to be as it should be. I have also compared this plan to other plans and the settings are the same.??? Thank you again.
