The basic usage of this add-in is explained in this video: https://youtu.be/9LbPzTZ3tG0

There are two modes: normal mode where you create a box full of Voronoi cells and an advanced mode where you select a body to fill full of Voronoi cells.

Common to both modes, you specify the number of cells (Cell Count), Cell Wall Thickness, Hole Strength, Hole Threshold and optionally a Random Seed.

Cell Wall Thickness is how thick the walls of the Voronoi cells are.

Hole Strength is a number between 0 and 1 that is used to determine how big the holes are in the cell walls where 0 means no holes.

Hole Threshold is the minimum cell wall area that determines whether or not a hole is placed in the cell.

Random Seed can be any integer and it is used to randomize the layout of the cells.

In normal mode, you just specify the dimensions of the box.

In advanced mode, you specify a Target Body. For best results, the body should be a convex hull (polygon) but it will operate on anybody. If it is a concave hull and you specify Make Convex, it will try to reduce the body to the smallest convex hull formed by all planes of the body's surface. If you don’t specify Make Convex it will enlarge the body to form a convex one.

If the body contains non-planar surfaces, the results are not easily defined and probably won’t give the expected results. Also in advanced mode you can select Add Thickness, much like adding a shell.

Install:

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.

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 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.

If you please have any issues or suggestions for improvement, please contact me.

Large Cell Count takes time to process. Limited support for bodies with non-planar surfaces and/or nonconvex hulls. When using normal mode, the minimum dimension needs to be greater or equal to one thousandths of the maximum dimension.
