I am trying to make a site model for a project in school. We have received contour curves that looks like those in the picture below.
I want to model the terrain so that is gets the form of “closed terraces”, as in the site model below. There I have just drawn the contour curves and extruded them to the appropriate height. But, I can’t edit the extrusions, and don’t know how import more contour curves in an efficient way if I would like to make more closed terraces to make the terrain more “smooth”.
I and wonder if anyone have a recommendation or idea of how to achieve the desired result in a relatively efficient way. I attach the dwg-file below if you want to take a closer look at it.
