I wish by default, room separation lines were turned off in sections & elevations.
By default, these lines are cyan in colour and they are thick, so you really do need to turn them off before doing any kind of printing.
Isn't it unusual though that these lines are even on in elevation & section to begin with? For what purpose would you need these on? You can't even use the 'Room Separator' tool in elevations & sections!
I have this turned off in my view templates, but I still find it a bit of a nuisance, Autodesk help us out?
