# Sine wave around 2D circle.

Hello,

Trying to make a sketch with two elements. First element is a circle, second element is a sine wave that follows the circle.

Thanks!

Tim

(rough) visual of what I am trying to do:

I don't know the equations off of the top of my head, but look into the equation driven curve for your wavy line.

that is very rough sketch

What if you create the points you want to have the sine wave go through and have a closed spline connect the dots?  I’m a recovering architect and not an engineer so I’m not sure this is a true sine wave but it could put you on the right track…

You can do it similar to this:

Nicely done Charles…  I guess I did not read the question right, he needs the sine wave to be in the same plane as the circle.  I did mine where the wave is perpendicular to it.

Yes, the thread I linked to shows how to do it perpendicular to the circle. The one I attached to this thread shows how to do it in the same plane as the circle.

Create a Sketch on the Top/Bottom Plane.

Select the edge of the Surface Body.

Convert Entities Tool.

Hi Charles, can you please let me know the steps how you have used sweep operation to get sine wave around the circle.

I'm trying to replicate the operators, but I could not get it.
