I need to make a site model and have an old survey supplied as a DWG. On import the survey is 3D polys which I have converted to 2D polys and I am using the combine connect tool to remove line breaks. The problem is, every 2nd or 3rd line it will either not connect, cause one side to disappear, cause the contour line to change to an odd shape, or crash Vectorworks.
Any tips on how to import survey data from a DWG and use it to create a site model?
