How to work on a detached garage with Auto Roof turned off

[RDJunc]

Hi.  I have designed a modest house that has a 48" second story that is finished inside.  To do that, I had to turn off Auto Build Roof once I had the roof the way I wanted it.  As you can see from the picture, I now want to add a detached garage.  How do I work on the garage with Auto Build Roof turned off?

 

I have Home Designer Architectural 2025.

 

Thanks.

Well I sort of figured it out and sort of not.  I was not able to work on the garage without turning the Auto Roof Build back on. It is always risky because things can easily blow up if I don't do things right.

 

To get the roof connection between the garage and the house, I added a patio between them with a roof above.  I had to match the heights and pitch but the overhangs made the final connection.  The patio could not touch either building.
