The "Data Matrix Creator" app is a Fusion add-in.

Usage:

1) Under the "Create" menu, click on the "Data Matrix Creator" button to create a new Data Matrix and open a command input window.

2) The command input window contains the following options:

• Text to Encode - Enter the required text to convert into a Data Matrix code.
• Cell Size - Set the size of each black square "cell".
• Border - Include the "white" border around the Data Matrix code. 

3) Make the required changes to the options.

4) Click on the "Preview" button to create a preview of the Data Matrix code.

5) Click on "OK" to accept the new Data Matrix code or "Cancel" to abort the command.

Install:

Double-click on the downloaded MSI installer from Autodesk App Store to install the add-in.

Uninstall:

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 Fusion.

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 and Features' (Windows 10/11), just as you would uninstall any other application from your system.
