It says in the Guide, on the 'How to design a split-level house' page, "The elevation of a level may also be negative to design a basement or foundations."
I have set the level of the basement at -255. But it's not working. I've included a picture.
After creating a new level, 'Basement', and setting its elevation at -255, I started drawing the walls. I set the walls at 243. I drew 4 walls. Then I looked at the 3D model and saw that the elevation wasn't having any effect.
The 4 basement walls I drew are in front of those stairs in the picture. They appear to be 12cm high.
So to summarize, the basement is at the same level as the main floor, despite basement elevation being set at -255 and the Main Floor elevation being set at 15. What am I doing wrong?
