I've had this problem before but now its a big problem. I will start at the beginning. I created wall for this addition I am drawing by starting with a square, offsetting my wall thickness and pulling that up to the necessary height. I went ahead and drew some cabinets on the wall. I usually draw them on the floor or wall and pull them to there height/depth. I drew a window and pushed it through the wall. Well now it seems that the interior plane of the wall is not there so now that I have drawn siding on the exterior is shows up on the interior. Please help, how do I make that plans solid again?

Thanks

I am inserting some crown molding as a model and when I insert the same model in a different location any editing i do to the new one effects the first one. How do I fix this?
Thanks
