Gable Roof at Front Won't Center

[KnotSquare]

The gable roof I placed at the front of the home will not center within the room so that I can design architectural trusses accurately within. I drew a CAD line down the center, and if you zoom in, you will see that the ridge of the roof planes do not quite match up.

 

I added interior walls between the Kitchen and Great Room just to verify that it was not the invisible wall causing this issue. I can't seem to solve the problem.

 

Any suggestions?

 

Thank you,

 

Mark
