How do I straighten out a line of vertices?

How I straighten out line of asymmetric vertices?

How many vertices?

In a 3/4 ring, or a horse-shoe shape. Maybe a few dozen.

Why would you want to straighten it if you want to keep that shape? Maybe post a picture.

Along the Z-axis, they are not vertically aligned.

scale them along the z-axis, and set the scale factor to 0.

This combination: S->Z->0

Thanks for the question and the answer (key combination)! I’ve been wondering too how it could be done. Now, I know it!
