Thanks for the reply.  I've browsed the self help suggestions and tried several things to no avail.  I've attached a few pictures and the plan file as suggested.  Cheers.

Greetings.  I am having a roof issue in Home Designer Architectural 2021.  I am simply trying to extend the roof line of the single car garage on the right to meet up with the roof coming from the left side of the two car garage thus forming a gable tying back to the main roof.  The software keeps automatically building attic walls that can't be removed.  I have spent a day and half trying everything I can think of to fix this.  Any suggestions would be appreciated.
