Fusion 360 Comes with the usual CAD standard tools as discussed in the previous session in this series. Additionnaly you are able to download and use more tools form Autodesk. In this session we show you how to use the spur gear "add-in" to take your mechanical design to the next level.

This Session is number 2 of a 3 part series where we explore the uses of design tools in fusion 360.

Fusion 360 has many in-built tools that improve the user experience and make 3D design simple and efficient. However, even with all these shortcuts to design available to us, there are still many design tasks that are either, very difficult or very time consuming to complete. There is a solution, as with most things to do with software. Repetitive tasks that fit that description will often have been come across before and it is highly likely that some clever CAD guru has written a script that is able to do a lot of the grunt work for you. Fortunately Fusion 360 has made it super simple for you to gain access to these scripts, unfortunately some of the scripts are so beneficial that the Autodesk team have decided users must pay to get them. That aside the free add-ins are still very good, and some come pre-installed. One such add-in is the Spur Gear Script.

In this session the use of the Spur Gear Script is demonstrated. There are a few settings that can be confusing at first but what you need to know is covered in the recording. Below is a brief step by step example for how to create a simple spur gear:

In a Design click the Tools Tab.
There you can find the Add-Ins Tool
The Tool will present all available scripts, here you will find the SpurGear Script
The script will present this window. For a gear-set the designed gears will generally have the same Module and Pressure Angle.
For design, you can leave the backlash and Fillet Radius at 0. But for now know that backlash is the offset distance for a tooth. 0 Backlash in a physical gear will not work. Select Ok and Generate your gear
Your gear is produced

The following session recording goes through designing a simple set of gears. How to align them and get the gears rotating as they would in a built example.

Session Recording

In the next part of the series we will discuss creating different types of gears. The options you have here and the add-in/script you can get free to help you do more with fusion 360.
