Well, Kindof. Your geometry shows "all Radiused Arcs" that makeup the shape "fairly close". "Turning on the control points for all your arcs will have them lineup as in the second picture I posted (with red arrows) where the 2 lined up. Since we are tracing a bitmap (not exact) I needed to look for some kind of "indicator" of drawing something "correctly" vs. Just drawing something "close".

Both wabble on and off the bitmap appearance a bit, but your model has some sort of "symmetry and order" vs my result which has no order. I would tend to think that the model with some sort of recognizable "order" to it's construction would be the original intent. ????

The basic question was more, "If something from this layout had you just say, "Look, it's a sphere and a triangle with a g2 fillet" or something very simple like that.

More was you just did a trace, and then your experience turned it into something tangible. Though I cant figure out how you got "all arcs" out of the shape.

Can you shed any light on this part?
