there are multiple ways:
us a featurescript (by @Pascoe):

or create a helix on a cone. (and if you need a flat spiral, you can project it onto a plane)
One of the multiple ways:
Helix curve then use Edit curve to planarize and reapproximate (smooth)

.
I forget the
Edit curve feature exists. @GregBrown you keep doing amazing things with it.

You can actually achieve a flat spiral with the helix tool without needing the edit curve step if you use the axis mode and draw to an end point. I was messing around with opHelix when writing some curve features and it supports flat planar outputs as well as cylindrical / conical outputs. Weirdly though it doesn't support cylindrical AND flat outputs simultaneously (i.e. a flat circular arc output) so I had to write my own 3d circular arc functions to compensate.
