The strangest thing…I would have thought that the 1st Radius would be in the 1st Angle direction and the 2nd Radius would be in the 2nd Angle direction - which is how it worked on the back armhole curve. But the diameter lengths are switching around:
I’ve tried changing the Angle at the bottom, but that only turns my curve around the centre point.
If I switch the 2 Radius formulas, then it works fine:
Duh! ok, I figured it out… The Ellipse is always drawn from 0 degrees all the way around to 360. And it’s only the Line of the Ellipse that is drawn from the one angle to the other.
I’m going to leave this on here in the How to… section so that others may find it
