Distance doesn't seem to work right

[zoster (Andrei Raducanu)]

If you zoom in, the end of the curve isn’t on the circle. Any idea why? (doesn’t seem to be the tolerance value)
Thank you!

The end of the point is not on Z=0 !!
Or you project the spiral or the point

You can also move the circle up

Thank you for the help, didn’t think of that!
