Racks and gears maker

Racks and gears maker

Win64, English

The application creates a rack with gears for straight, helical, double helical and herringbone teeth.

General Usage Instructions

You can find the add-in under the 'CREATE' panel.

For creating gears you have to run this add-in. The window has default parameters so you don't need to set them at the start.

The best option for running add-in is to do this in a new, empty document. Otherwise, you'll have to hide other components or bodies to avoid cut/join/intersect operation and probably error during processing.





The installer that ran when you downloaded this app/plug-in from Autodesk App Store has already installed the app/plug-in.

OR, simply double-click the MSI to install the app.


You can unload the add-in without uninstalling it by clicking the "Stop" button when the add-in is selected in the list box on the "Add-Ins" tab of the "Scripts and Add-Ins" dialog.

Unchecking "Run on Startup" causes the add-in not to be loaded in future sessions of Autodesk® Fusion 360™.

To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button.

OR, you can uninstall it from 'Control Panel\Programs\Programs and Features' (Windows 7/8.1/10), just as you would uninstall any other application from your system.

Additional Information

Plugin directory

The plugin creates a directory inside your Autodesk® Fusion 360™ installation folder. This directory contains files with last used parameters provided by the user and error files (if occurred). The Name of the folder is Racks_and_gears_maker_settings. Both last used parameters and error files are regular JSON's so you can open, edit and check them by simplest text editors in any OS.

Sensitive data

No user data are stored and no Internet communication is done by the plugin.


In case of error, you'll be informed by a dialog window, where exactly the file has been written. As mentioned, you can easily check the file content using the simplest text editors. If you want me to reproduce the error you can send this file to me (as an attachment or as text) but it's your decision if you want to.

Known Issues

The program has been tested for 43 cases with various sets of parameters. Most of the errors have been found and fixed but it doesn't mean that they won't appear for some configurations. Generally, all of them have their source in the way how bodies are joining/cutting together and strongly depends on the general precision set in Autodesk® Fusion 360™ preferences. When you encounter an error, first try to slightly change the parameters (if possible), for example, set groove width as 10.58 instead of 10.577, etc. If that doesn't help, contact me.
