Contour selection

When I am using the Contour selection in the 2D profile, it always puts my arrow on the wrong side of the line and I have to manually move it. Is there a setting I am missing to fix this?

It would be quicker if you would share an f3d file so we could look.

I am guessing that you don’t have an outside and inside contour for Fusion to understand that you want the cut on the inside.

The other way to make it very clear to Fusion 360 is to extrude a body and then pick the face of the body for “contour selection”. Nearly 100% success with determination of inside and outside cuts.
