I need to populate the Z Geometry Attribute of a point feature class.
I have the Z value as a field in the attribute table.
How can I script this process to avoid having to hand type the elevation valves when I have the data already?

Pro 2.7, file gdb.

If you know Python, you can also update(replace) the Z value from an attribute field.

Take a look at the answer from the following for a starter to update(replace) the Z

thank you, I'm bookmarking this for future reference! I used Feature to 3D By Attribute for this situation.

Does Feature to 3D by Attribute create an entirely new feature class or can this be used to replace z values on an existing one?
