Ceiling Lines?

[ChiefChris]

Clueless Chris here again.

When I have a roof plane that cut into the ceiling CA automatically generates a ceiling line with a blue dashed line. I appreciate that. But my interior designer gets confused when she sees those lines - (I dont know why...becuase she always asks what the ceiling heights are)....IN ANY CASE. Is there a way that those can be turned off? What layer are they on? I can't figure that out....

I can turn them off by selecting "no ceiling" in the room DBX, but then the room isn't accurate in an interior 3D view....unless I go and put in a custom ceiling plane....and I can't seem to hide them behind a CAD box.

I just want to turn the lines off so when I print the set of inaccurate, un-noted, un-detailed set of drawings for the interior designer she doesn't get confused....
