I wish to draw in openscad a motor mount for rc car.
Most of what I need I can do but cannot find a way to draw 3 of 1mm circles each exactly 8.5mm from center of 12 mm radius circle and exactly 120degrees apart.

Hi,

I do not know OpenSCAD as I use FreeCAD.

The solution is easy. Draw 1 circle and then use the function “PolarPattern” if that exists in OpenSCAD.

PolarPattern asks you how many circles you want in a certain amount of degrees, eg. in your case that would be 3 circles in 360°.
