I'm almost finishing this assignment but i can't do this little shit. I've tried using arc, fillet, spline and i can't reproduce this. I'm using Autocad 2017 btw
What i can't do is the thing the arrow is pointing at. pls help
Also, all measures are in millimeters
haven't done cad in years but i would guessstart by making the top toothset up the bounding (8x12) rectangle to get the start point of the left arcset up the interior (4x12) rectangle to get the end point of the left arc2-point circle on the points, with fixed radius, compute radius from arc length + chord length w/ https://planetcalc.com/1421/ or wolfram, it will be correct within tolerancesclip, flip, union to get full tooth, repeat around the circle.
