How to create a epicycloidal sketch in CREO 2.0?

[tconrad]

I've seen tutorials for creating cycloidal or epicycloidal using SolidWorks & Blender. Can anyone tell me where to find a tutorial or instructions on how to do this with CREO 2.0?

I'd use the curve by equation feature.  Then you can trace the curve entities in your sketch...

Equations for Curves (and more)

Or this one: http://mathworld.wolfram.com/Epicycloid.html

Here's an example in Creo 2.0:

You'll probably also want to construct one lobe and pattern if you're looking to create a solid. You may also need to adjust the angle used in the equations.
