I have several full height interior walls that are 300 mm wide with shelving between. These walls originally showed drywall on the ends of them, but now the drywall layer has gone showing the framing. This is in both the plan view and the camera view. Is it possible that I have changed a setting which has remove this. I'm not sure if this has anything to do with it but I started creating this plan in X9 and previous saved files are ok, but then I upgraded to X10 part way through the design.
