I am trying to grade a subdivision. I have created a surface from my road and I am now using feature lines created from the assembly along the right of way. I am offseting the feature lines 20' at a 2% slope for the drive ways. It will not keep the grade. In some places it works, in other places it ignores it. I have tried just creating feature lines going at a 2% slope for 20' and it will change the grade to something like 23% once I add it to the surface. How can it just change the grade on a feature line by itself?????
This is a simple site that has taken me 8 hours instead of 3. UGH!!!!!!!!!!
