Constant force spring model

[AntonioVillanue]

Does anyone have a model of a constant force spring? See image. How would you model this in Pro/E?

[DavidButz]

Probably the easiest way is to create a Curve by Equation for the spiral and build from there.

[DavidButz · Accepted solution]

For example:

This was started with a Curve From Equation / Cylindrical with the relations:

x=2+t*2

r=t*360*5

z=0

Then create a Sketched Curve, copy the first Curve with Use Edge, add the end details, and use this Curve to create a Sweep.
