Minimum triangulation angle

I have a surface from gradings which follows a curved feature line. The grading surface creation setting is set to minimum 3 degrees (default), and the surface appears just fine. However, the created surface does not follow this minimum 3 degree constraint, resulting in my curved feature line becoming a solid mass of tiny triangles instead of the source line for larger ones.

 

Does anyone know how to enforce the minimum angle constraint?

Sounds like when the FL was added to the surface it had a Mid-Ordinate distance of 1.0 instead of 0.1 which I normally use for breaklines.

How does that interact with the fact that this is a surface from gradings (and infills) and how would I change that setting acordingly?

We also don't use breakline commands in my company, it's just FLs in the appropriate sites, since that sounds like it may be relevant to the conversation.

Are you able to share an example file or some screenshots.  I'm not following what you are asking, and probably would have made the same assumption that Rick made, in that your mid-ordinate distance is too high.   If you are using grading objects, are you setting the tessellation value high enough?

Here is an example of the issue:

 Here's the surface from grading settings:

not sure what other points would be helpful, but there you are. Unfortunately we had to force it to change by manually swapping edges so I can't send you the file, but that's what it looked like.
