Hi All - I am trying to import an AutoCAD file as a terrain model into SewerGems Connect Edition. The Autocad file contains only 2D information (elevation and contour lines exploded) which is basically a Top survey over a large area. These are the only files in hand and we need to use them to build our Watershed area contribution to our project storm drainage. Would you please advise on the steps to import such a file for use Thanks. Marc Here's a Snap shot of the AutoCad Top file
