Watch Out for Elevation Data

Here is something important to remember if you are having difficulty with a surface after creating the surface with imported points (the drawing is crashing). Make sure the elevations are with in a reasonable distance to each other. If one of the spots is at 110' and a single other point is at say 985,659,268.000' and another point at 9,587.843' the drawing will crash when you want to show contours at a foot interval. Well I guess it wouldn't crash if you had enough memory to draw all those contours. I could see how this would make a decent practical joke on someone, especially on a surface that they have been working in for a period of time.
