qball Posted June 25, 2009 Posted June 25, 2009 I have an elevator pit that was dug into rock that I am working on. The surveyor sent us their data points (attached). I connected some of the dots and did some rough LOFTs. The result is attached. It's very rough as you can see. I tried 3dpoly and Loft to the contours, but it wouldn't work. Said some entities not valid. Is there a way for Autocad to interpret those points and create a surface contour? Or is a second program, perhaps Civil3D, required? 07-222Rock Walls Near Elevator.dwg Rock pit grade.dwg Quote
