Vertical entities uneditable with free vertical curves in Profile Grid View

[KimJG7V9]

Is there a way to have these greyed-out vertical curves editable? Would be nice to have the Grade In/Grade Out and Stations as editable instead of manually adjusting them in profile view which makes it hard to get to a desired grade (ie 16%, 15.5%). They are showing as unlocked but they are greyed-out.

If I delete the curve entity after the -15.96% grade, and change the -15.96% to a whole number ~16%, it says it could not solve.

Thanks.

Hi @KimJG7V9 

They are grey because they are defined to depend from other entity.

Can you share your file to take a look?

Hi,

You have used Free Vertical Parabola to create those uneditable curves. This means you are create a curve by connecting two tangents which sits apart.

Curves will be editable only if they are created from Free Vertial Parabola (PVI based). Then the tangents are connected before adding curve.
