I am trying to draw a mesh from a terrain. It hasn't to be quite detailed, lets say 1/1000 or 1/500. I don't have a surveyor plan in DWG. I only have a PDF with points and its high "Z". The problem is that one of the roads is made for a curve with lot of nodes, I only have the "z" coordinate for some of them. So my question is how I can make that the points, between the other points I know the "z" coordinate, with a continuous slope.
