I can't figure out how to do a laser path. The picture has a red squiggly line that I started with a spline. I was wondering if there was a way to pattern a "sine wave" looking radius or line similar to the spline I hand drawn (but uniform - not a hand made spline). The sine wave can be radiuses that are tangent. The length of the wave can be 2-3 mm pitch (doesn't matter that much). It needs to fit in the "raceway" pictured below, but go all the way around.

I tried making a surface and doing a curve pattern, but couldn't figure out how to make it work. I suspect this is a "intersecting surfaces" job (I don't know how to do anything in surfaces, they frustrate me). This could even be done in a 2D sketch, because the output will be DXF for my laser guy.

I included the simplified SolidWorks **2019** file.

Thank you for any help you may give me,

Hi Jeff,

Yours looks doable. It doesn't have to be perfect. The laser will follow the path you have provided. Thank you,

Dan
