Hello,

Im looking for a way to let the walls of the 1st floor (or 2nd) start from above the floorhight.

for example: wallhight is 2500. then I put in the 1st floor with a thickness of 300. The walls on the 1st floor start on top of the walls of the groundfloor, not on top of my 1st floor wich would be 2800 hight.

I've tried with rooms and adjusting severall hights. But I can't seem to get my head around this.
