Roof and Exterior Wall Raise?

[MississippiMims]

I'm trying to raise the exterior wall height and therefor the roof of the house in the screenshot to the blue line approximately.  I cannot raise the ceiling height in the room dialogue because it effects the second floor.   I need the ceilings to stay the same so the second floor will be unaffected.  I can manipulate the wall height by moving its polyline in an elevation view but then how do I get the roof to follow so that it sits on the exterior wall top plate?

If you are auto building the roof, research these settings.

 

 

 

If manually building, or you have turned off auto rebuild, select all the roof planes and Transform/Replicate.

Thank you for the direction Eric.  I had seen that setting but never used it until I researched it.  Luckily I still had auto rebuild roofs on so it was as simple as raising the roof 24".  I did have to go back and turn auto rebuild roofs off so I could lower the porch roof.
