Correcting Surface Triangulation

[Anonymous]

Hello,

Attached is a DWG file with a couple images showing areas in my surface model that I need to correct the surface triangulation. It appears that there is not very good triangulation in these areas, and it is causing incorrect contours. I understand the concepts of swap edge and add line, but I cannot find a combination of these commands that will fix the triangulation in these areas. Any tips or tricks that I could use to fix the triangulation in this area will be very helpful.

The surface was created using grading objects.

Thanks in advance.

I get an error when I attempt to view your images, and I'm leery of downloading outside dwgs.  But if you're having trouble editing the triangles, perhaps adding a few more points to your surface will allow you better control of the triangulation in your area of interest.  

Prospector > Surface > Edit > Add Points, and select some points along your tin lines, or triangle faces.

I think its a matter of too much data on the Grading Group 1 surface.  Edit that surface to remove the intermediate surface points mid-way up the corner locations.  Then add a line linking the top corners to the bottom.
