Interpolation and breaklines

[mbmiller34]

Is it possible to utilize breaklines when rasterizing with interpolation? I have my drone data and then I have my GPS data that was collected in a 10x10 grid with break lines. In particular, on this site, I have a ditch on the south side that when I interpolate, connects across the ditch as well as down to the toe.

Nope, that's not possible.

You can sample points on the polylines and then use these points in the Rasterize tool.

You can also create a mesh between 2 polylines (and then sample points on it but that's probably not super applicable to the generic case).

Is there any way to prevent my points from connecting across the top of the ditch

[daniel]

Which points in this case? Which path did you choose? (maybe a small snapshot would help).

[mbmiller34]

Hopefully, these images make sense. What happens is CC connects across the top of the ditch due to a lack of points. Manual GPS 10x10m grid to pick up low areas drone was unable to measure. So rather than having a true typical ditch profile I have weirdness. I can create it inside GM using manually defined break lines. Drew a polyline down the crest and toes but there should be a way to create the same inside CC. The blue low area should be running the entire length.

Ah I see. Sadly CC doesn't include the option to use polylines as constraints in the mesh.

[mbmiller34]

Are there any methods to prevent the 'across the top of ditch' stitching from happening?

[daniel]

In CC? I guess you have to manually add points at the bottom of the ditch ... Maybe create a mesh between the two toe polylines, ans sample points on the resulting mesh? It will be very manual though.
