Sorry, somehow missed the tutorial on sloping ceiling guide.
This is exactly what I need!
This is still knew to me. I am a machinist / engineer designing a house. Till now my 3D experience has been with "parts" I was going to machine and for that I used either autocad or solidworks.
I was just going to do 2D plans but my wife can not "picture" the house so I started using this program .... it's great!!!
