trying to create a plot plan and need to create topo that slopes in 2 directions from the house. dont have a survey with topo available so creating the topo from scratch. accuracy isnt really important going more for looks so the elevations look correct. what is the easiest way to do this. i have created a topo surface that is flat as the lowest point of the grade but now i need to add contours for the stuff that slopes up. any ideas?
