Overlapping Segment

I'm running Roadway Designer with Geopak V8i SS2. When I create a surface from the corridor, I get an error of "overlapping segment" with a long list of points and the resulting surface is incomplete. This hasn't always happened with this corridor so what is causing it and how do I fix it?

  • You mention it hasn't always happened. Does that mean this corridor was working as desired prior to some change you made and you are now getting the message overlapping segment?

    Did you change anything on the template?
    Did you change the drop interval?

    Just fishing for more info.

  • Yes, I have made numerous changes to the templates (I have several with a lot of switches, parametric constraints etc.). I took over the corridor from someone else who left and had to make some changes, but tried to do so without removing backbone components so as not to unknowingly lose some of the point controls or constraints. That being said, it did run after I made these changes, but doesn't now. What's weird is that the points listed in the overlapping segment list are backbone points that have not been changed and they range from beginning to end in the corridor.

    I did break up the corridor into sections and I have been able to create good surfaces that way. I don't know if the entire thing was too much to process or something else is going on.
