In the general display properties & the room object display properties the layer set I'm working with has ceiling break lines, planes & surfaces all turned off. The only way I have been able to turn off ceilings in rendered views is with the turn ceiling on/off commands when selecting each individual room. Is there another way?
OOPS. I didn't realize the layer set in the rendered view could be toggled & set on or off. Thanks, I got it now.
