Help creating an flat spiral spring in NX5

[jmoth79]

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

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.

Please try

Curve ==> Helix
Number of turns 3,5
Pitch 0
Radius ==> Use Law ==>linear value 22,5&35,25

Life shouldn't be measured by the number of breaths you take, but by the number of times when it's taken away...
