Help creating an flat spiral spring in NX5

Help creating an flat spiral spring in NX5

(OP)
Could anybody assist me with creating a flat wound parameterized spiral? The start point at R22.5mm, 3.5 turns, ending at R35.25mm.
Do you use the helix command or perhaps law curve?

Thanks in advance!
Jason

RE: Help creating an flat spiral spring in NX5

What version of NX are you using?  If you're just doing a spiral, try a Helix using a Pitch of zero and a Radius Law.  If that is not what you're trying to do, please provide at least a picture of your desired result.

To an Engineer, the glass is twice as big as it needs to be.
