Ants, Agents and Automatons
This post shares some basics on creating gears in Fusion360.
At the end of this tutorial you will have a fusion design that could be printed to yield a simple gear pair like those below.
I am going to take advantage of an excellent post by productDesignOnline.com and simply point you to their video.
But before we get there, there is an important change ….
NOTE:
At 0:54 in the video below the creator accesses a script called the Spur gear add-in. The process to get to this add-in is no longer the same. The tools menu they reference no longer exists (at least in my version of F360).
You will follow the instructions at 1:07 instead.
For each gear you want to make, you need to follow these steps to load the add-in:
Press < s > to open the Design Shortcuts menu.
Type <script > and choose Scripts and Add-ins…
choose Scripts and Add-ins

A new drop down will appear. Scroll to the bottom and pick SpurGear. There are two versions – one written in C++ and one in python. For our purposes, they are identical — so pick either.

Click < RUN > once you select SpurGear add-in.
Unlike in the video, the script is NOT added to any menus as a part of this process.
The rest of the video is straight forward and excellent.
