Hey everyone! I am a new member of Vectorworks. I watched the lesson on (from your channel) and wanted to repeat, but it was not easy. I prepared a flat drawing of the site in AutoCad in scale 1:1000, after imported to Vectorworks 2016, chosed "2D" and my scale. When I tried to do "Survey Input" - "2D Polys to 3D Contours" I received a message "No 2D polygons found in this layer. Be sure 2D polygons are present and try again. (I want to notices that I try with 4 different drawing: with closed and open counter, in 2D and 3D (made by Autocad). All the time was the same message, but with 3d drawing of the place I received :"There was no valid 3D data selected to user for the Site Model source data. ...." Please, could you convert my drawing to 3d relief and explain it how to do. I have no idea.
