David, 
 
	    Thanks for the advice, I'll get to that shortly.  In the mean time I am using Chief Architect X15 on an Alienware M-18 with RTX 4090
 
	I built the structure as a deck and placed the roof over it and I just want to remove the ceiling material and show the exposed rafters.
 
	Any feedback you could provide would be greatly appreciated.
 
	Thanks so much,
 
	Randall Morgan
