I'm using dtm input from the Cross Section Reports. I'd like the triangles from this to be a little finer for the geology surfaces I'm building. I want to create more accuracy within the tin I create from it. Ultimately, can I force certain points to be vertices of the triangles and can I get more vertices on the dtm? I've tried breaking my geology lines into segments and it does alter the triangles, but not always in a positive way and not in the way I want.

I don't think creating additional sections is a reasonable solution. I'd be doing it strictly for me - I'm not the engineer on the project, so if they got something back with 50 additional sections on it, they may get cranky. I'm not responsible for creating anything regarding the road corridor and alignment, only the geology/subsurface layering. Creating more sections would not solve the problem of lack of inflection points at the top of backslopes, where a significant gradient change occurs. As in the attached pic, I would like triangle vertices to fall on the orange points, but as an example, GEOPAK will randomly choose the blue points. The dtm created from these points will be off, as it will trim off the upper corner of the surface, then extend over the groundline at the bottom part of the slope. If I could get it to use the ends of line segments, I could create surfaces with much greater accuracy.
I'm not finding the option you are talking about. Here's my dtm creation window view. Should I be looking somewhere else?
Also, some of your links are broken on in your Geopak support clips.
