I had a look at the drawing but I don't see what you are trying to grade
from - everything is at a 0.0 elev. You'll need a polyline around the
building at the correct pad elevation. The surface elevs are around 850, so
your building pad should be somewhere in the 800's.
Even if you have that, your surface has a hole in it so there will still be
a problem with trying to project a 3:1 slope to the surface..
