This is an add-in for Autodesk® Fusion 360™. Selecting multiple pitch circles, it places spur gears at the location of those pitch circles. It also automatically meshes the spur gears together.


  • Pitch circles in a meshing relationship cause the spur gears to be rotated and positioned at an angle of meshing.
  • Whenever there is a combination of pitch circles touching each other, multiple combinations can be converted to spur gears in a single operation.
  • The sketch plane for drawing pitch circles is not limited to the XY plane. Pitch circles drawn on any plane can be converted.
  • Each spur gear is created as a separate component. Therefore, it is possible to set up motion links between spur gears.

    I've been looking for something this easy to use for a while, it's obviously still in development but what's there is good.

  • just missing the internal gear
    Alexandre Richet | February 02, 2023 Verified Download (What's this?)

    the way it does the gears is really cool simple then it seems really well done especially for 3d printing i just wish it managed the internal gears to be able to do planetary boxes

    Noriaki Tambo (Publisher) | February 06, 2023

    Thank you.

    Thank you. For internal gears, a similar structure should be possible if the hole diameter is larger than the outer diameter of the gear. However, I have not been able to confirm whether the gears mesh exactly.
