Wheel from 3D to 2D

Hi everyone. Can anyone guess how is the 2D version of this wheel? I’ve searched for it from other angles with no success. I want to design only the sprockets, not the central part, just the “arms”.


Just rotate the present ellipse a bit CCW and then non-proportionally scale to circularity in Photoshop, then put the image in a Rhino viewport.


I didn’t understand what you explained but thank you anyway.


I think it’s basic model, you must try yourself with extrude 2d lines and find the similar shape. I guess roughly this shape.
