What's the best way to draw an arc in ArcGIS Pro?

The 'create features --> create circular arc' only works for 2D (from what I can see).

I can import a table with coordinates & Z field, but just wondering if this is the best way.

Screen capture - I would like to create an arc as shown in the example below:

Where you able to get this figured out?  I'm sure it is possible, but I'm just overlooking some small item.

I figured out a way to create the 3D arcs manually.

It’s a multi-step process that involves creating a table of X & Y for all the points of the path you want to turned into a 3D arc, then calculating the Z value (in metres) using a formula: X^2*-1 + D2.

I was planning to create a model for the process.

I’m happy to share the steps with you (or the model if I get around to making it).

I was hoping to find a more efficient way to do this, or even better, an ArcGIS tool to do it for me! I suspect you’re after the something.

Yes, I would be happy with either.

Thank you,

What is D2 in your formula: X^2*-1 + D2?
