That's exactly what I did. Thanks for Your support.

Hi!

I think the best is to use formula instead of specific value for slope constraint.

Point 3 has slope constraint to 4 and instead of value i wrote formula that slope between 3 and 4 should be the same as between pont 1 and 2.

now each time when top slope will change, bottom slope follow the same.

Hope it is clear.

Regards,

Martyna

Not bad idea at all.

Thanks.

Here is something quick I put together. Point 2 in my template is the new point you must add. It is constrained to Point 4 (horizontal = 0, vertical = h). And then constraints for Point 3 are shown in the screenshot with the vector offset.

Thanks. I almost got You, but not quite. May I ask You to show it graphically...?

You need an additional subgrade point constrained to cela_mala (horizontal = 0, vertical = h). Then grants_apaksa will be constrained to this new point (horizontal = x, vector-offset between ass_grants_apaska and the new point with a value of 0).

Additionally, the subgrade points do not need to have superelevation flag checked.

Guys, thanks!

I defined that subgrade edge follows surface edge by constant "h" value as well as slope is defined to follow surfaces edge's point. I attach printscreen. Is there any more efficient way? Or can these definitions compromise me any way?

P.S.I do appreciate Your effort for quick response. Respect!

Constraining your subgrade points to the surface points (which are controlled by the superelevation point control) should make it work. For example, a subgrade point would be constrained horizontal = 0 and vertical = subgrade depth.

How are your points defined for the subgrade? By the way your template is behaving I am assuming the the subgrade point is set as a distance & slope from the center point.
