Ceiling plane cuts wall at bottom

[mtldesigns]

Happy 4th of July Chiefer's.  Hope you all had a safe and enjoyable holiday.  Now the that the fireworks are done, time to get back to work.  :-)

 

I know how to do dormers and have the roof cut walls at the bottom.  But in this case, I have a dormer, but the ceiling is a different plane than the roof, so I need to cut the wall at the ceiling plane.  Anyone knows how to do this without filling gaps will polys?

 

Thanks in advance.

Ceilings won't cut walls for me, but I'm not that adept.  I posted a plan recently with a question like yours, got no response, and made the required wall fills with p'solids.

Had to keep the ball rolling.. so that's what I did as well...

 

Got some rain coming your way it looks like.. be safe down there.  Crawfordville is out of the cone.

Build a roof hole polyline around your dormer... like ~12" beyond it's walls... just rough it in.   Now you will see that your dormer walls will go down to the ceiling framing.   Now select the main roof plane that the dormer is placed in, open it and select No Special Snapping.  Now snug your roof hole up to the outside of your dormer walls.   If you don't turn off special snapping, then the roof hole will automatically snap to the inside of the dormer and cut off your walls at the roof level.
