TIG, thank you for the help. I think I screwed it up when I did the layers and grouping. Old CAD habits Thanks again for your help. I'm sure I can get it to work now.

Maybe I used the wrong intersect method. The cut lines are on my wall layer and they are showing through the top of my roof. So when I go to delete them they delete the walls. Apparently, I have done something wrong . I created the roof by using the follow me tool around an 18 inch overhang with the roof profile. I appreciate your helping me

I created a house model and used intersect with model to cut my walls to the roof for a vaulted ceiling. My question is how do I get rid of the cut lines created on the roof from the walls? Any help you can give me will be greatly appreciated. Thanks
