What's the best way to sketch a shape like this outline? (lemmy.ml)

I've tried using a B-Spline, using eliptical arcs, and making a polygonal approximation and then filleting it but none of them worked well and both were very hard to figure out how to measure for.

The best way would be to put this on a 2d scanner, load the image into FreeCAD, scale the image using a known measurement, and then using a spline to draw the outline over the scan (don't forget the symmetry!). Working with splines is a science in and of itself, so you should watch a few tutorials or read the docs.

Ahhhh that seems like a good way to do it I'll try that
