Can't generate tool path on circular segment

[enkoping]

I try to generate CAM toolpath in Fusion 360 on a circular segment. I use 2D Contour whit a 5mm endmill.

This generate a warning. "Warning: Closed contour has 0 area."

I have tried different dimensions on both figure and the endmill. It works fine with half a circle, when it's more than a half a circle and every other shape I can think of.

I recall seeing this before. I think the solution was to break the arc into two moves. This can be accomplished with a "split face" line or a sketch that is also broken in two.

Thank you for your reply!

That was an easy fix to get me going again.
