Let me start off with this being the first time I have tried to create a proposed surface. I have created my existing surface with no errors. I have created my feature lines (building outline). I have tried to use the 'Create Grading' and added in the information it asks for. My 'Grading Group' says that I don't have any information in it. If I click 'Create Grading' and pick the feature, pick a side, give a distance and slope; CAD seems to randomly draw in 1' contours that do not tie in to anything. How do I create contours to tie the finished floor elevation into the existing surface?
