The higher part is 270cm high, the lower is 210 with a little slope at the end down to 170. I made this as two separate levels with height 270 and 210. I don't know if it's good way to do it but it's the only way I could get this difference in height visible in 3D mode. However, I can't make this slope visible and no matter what i try it always looks like plain ceiling 210 high. I did everything accordingly to the manual I found on the internet, and also I did it the same way i did it on the highest floor of my house, for which it works perfectly:
I don't know how to do it and would be very grateful for any advice. Here's my file, if you'd like to take a look:
