I have converted my .dwg elevation file (supplied by survey) to .dxf . I have made several successful drawings and the terrain displays properly. I now have a new drawing I started. I imported the same .dxf but the only terrain showing is the part under the building. It looks very funny, I can change the thickness of the display and my house rises on a tall green pedestal! It does not display the entire terrain perimeter. If I click off on the "do not display terrain intersecting building" then I loose it all together. I have tried to follow the same settings as my successful plans. I have tried to reload the data but I end up with the same thing, no full display. I know I am missing a button somewhere, I just can not figure it out.
Does anyone know what I am doing wrong?
