I use CCPro (and CC3) for Campaign and City Scale Maps
and I use Dundjinni for Detailed (1"=5' Scaled) Detailed Maps
A Note about DJ : It is a Java Platform Application to Make it Crossplatform so Mac and PC Users can Use it. It is a Memory Hog. Yes It does Bog down quite a bit. Still I won't give it up for anything to map detailed maps.
Just got CC3 Disc and am still awaiting the DD3 Disc so I have not tried it yet to make any detailed interior Maps
