Easy way to plot X-Section low points on profile in GEOPAK?

Does anybody know of an easy way to plot low points on X-sections, like ditch bottoms, on the roadway profile? Right now I use Active Chain Control and multiple View Windows to do it but it takes quite a bit of time.

Thanks,

That tool works pretty well, until the proposed foreslope ties into the existing ground at a higher location than the bottom of the existing ditch.

This might be clunky but couldn't you place a water drop trail which will follow the low point of the ditch and create a chain from the trail then profile it and project it onto your road profile?

That's a hell of an idea. I'll have to try it.

In order to get the low points of both existing and proposed ditches, I'll have to merge the DTMs first.
