Buggy - Create Contours on Plane or Flat Surfaces Areas

  • 1.  Buggy - Create Contours on Plane or Flat Surfaces Areas

    Creating contours on flat or planed surfaces areas seems like it can be buggy and doesn't always accurately depict the surface. In the surface shown below, I have a surface with a bottom elevation of 450. You can see that the contours spike across the surface in areas. I am not sure why? Maybe because of the wire frame? Is there a way to correct? I tried turning on "Adjust flat Triangles" in the surface menu but that did not make a difference.

     

    As of right now I would need to go in and delete the 450 contours and use the track contour to create my own 450 contour. Not a big deal but if I modify the surface (which I probably will because this is a design project) I will have to repeat this process. Then this becomes a bigger nuisance.

     

    I have run into this before on other entities such as top or berms and bottom of ponds.

    Elevate the line 0.001 over the elevation.  When you interpolate an elevation the beginning or ending elevation when set to an even number can be difficult to interpolate. When working with points that have varying elevations you don't see this, but using even elevation contours in a surface the program can miss the first or last elevation.
