Surface doesn't match the grading

[karlkarpuk]

Hey!

I applied grading to a curved feature line. The grading looks just fine, but the automatically created surface has very little points at curved parts as you can see on the image i attached. Why is that so? I need the surface to be as smooth as the grading.

You can try reducing the Mid-ordinate distance to a smaller number when you add the breaklines to the surface.

I didn't use breaklines at all. I just took two curved lines and used grading. Can the problem be avoided with this method as well?
If it makes any difference, i created the featurelines out of objects (polylines).

Karl,

Can you post your drawing?

I didn't want to attach the original file since it is so messy. It doesn't matter though as i attached another small file where the same problem comes out.
The bigger grading surface looks fine because of the scale, but the smaller one relatively doesn't match the grading at all.
It's about how many points grading will go through and i don't know how to change that.

Okay i found what controls that. It's the grading group surface tessellation spacing value... i have a lot to learn, hehe.
