Zero Platform Thickness

[Richard Satterfield]

I am using CA6. I created a design with 8’ ceilings. After the design was nearly complete (i.e. stairs, floors, ceilings, roofs etc.) I changed to 9’ ceilings. After some work I got it so that everything looked pretty good with 9’ ceilings. I was starting to feel like the master in my relationship with Chief ... and then I noticed the properties window for the top floor rooms showed a platform thickness of 0" with the lost thickness going to a higher ceiling in the rooms below. I don’t know when the 0" thickness problem came into existence. I assume it resulted from changing floor heights but I guess it could have resulted from some other thing I might have done. A cross section shows that the platform thickness really isn’t 0". Instead, it appears to be normal thickness. The joist framing properties window shows proper joist dimensions. The floor default properties window for each floor shows normal platform thickness. I have rebuilt floors and ceilings (and roofs) lots of times.

I have run out of things to try. I will appreciate any suggestions.
