    Contour Lines not displaying correctly.

    What is the easiest way to correct contour lines when they don't display correct?   Adding points, deleting points, switching edges... 

     

    See everything circled in orange on attached pdf.

    Assuming that is a corridor-related berm you've created, it looks like you have some targeting issues, maybe? Hard to tell.

    What do you mean by target issues?

    For example, in the area marked "Two C Pipes", the contour issues look like the something is amiss, perhaps, with the berm grading back to existing grade? Lots of things can be causing your problem, I'm just guessing at one that might be a cause.

    If this is an exisitng topo or a feature line or a grading design I would be fixing the breaklines and/or removing the bum shots creating these issues. What I see in your file is what I see in our files when the surveyor used points in the surface for objects sticking out of the gound (or underground) like top of hydrants, top of headwalls, (pipe inverts) etc. or when breaklines are required but are not modeled.

    If you added contours to the surface definition I would make sure that you have the Minimize Flat Areas option checked. This should fix the errant contours going over the flat areas.

    Answer to my own question:  I changed the contours to show every 1.01 and 5.05 instead of 1 and 5.
