How to create a part of "third ring piston" in NX?

Question by Erika Rose

I would like create teh third ring for a piston, but the "yellow" piece I couldn't create... I was trying "Law Curve" command, but I don't know the mathematical expression to use. Is it possible in another way? Or someone could show me the correct expression?

Thank you

Hi Erika!

I would sketch part of the shape and then pattern the rest of it as needed.
Then model a cylinder and use Wrap command to wrap the sketch around the cylinder. Then you can use Law Extension to extrude the wrapped sketch according to the cylinder face. Finally thicken the surface and apply necessary blends or chamfers.

Example made in NX10.

Attached is a method using law curves to generate a sinusoidal shape.
