Corridor Surface Boundary Eliminates Half the Surface

[shortbrandon]

I am grading a culdesac, and I have a corridor with two baselines (one for the north and one for the south side of the culdesac) in one corridor. Both are set to daylight to the existing surface. When I create a corridor surface and use "corridor extents as outer boundary," it only creates the surface for half the corridor (one baseline). If I remove the boundary, it completes the surface but of course it has extra triangles outside the corridor. I know I can remove the boundary and delete triangles as a workaround, but I'm hoping there's a better solution. I found another post from someone with this problem several years ago, but no solution was found. Screenshots attached show my corridor selected, the surface with the boundary added, and the surface without the boundary added. Thanks for the help!

In my experience when corridor extents gives the wrong results, there is usually a gap in a region some place

I did wonder that... the two regions of my corridor meet in the middle (evidenced by the double-sided grip) but I wondered if there's still a gap somehow.

another check is hide regions and observe the triangles

What do you mean?

It seems like the simplest thing might be to let the cul-de-sac corridor surface triangulate across the corridor.

Then it appears that you have ANOTHER corridor for the actual road as well as the cul-de-sac within the curb.  Add this surface as a HIDE BOUNDARY for the cul-de-sac surface.

Then you can paste the two surfaces into one composite surface.
