This script is used for generating voronoi sketches in Autodesk Fusion 360. Once created, these sketches may then be used for creating or modifying models.

Note that JavaScript development (editing/debugging) is no longer supported within Fusion 360. But existing JavaScript add-ins, such as Voronoi can still be installed and run.

Note, you can still add scripts implemented in JavaScript.

1. Run the "Voronoi" script from the Script Manager
2. The settings dialog will be shown. Adjust to your preferences:

• Sketch Selection: Select a sketch to insert Voronoi or none to create a sketch.
• Edge Style: Straight or Curved edges
• Number of Cells (2-256) : Number of cells created in the sketch
• Number of Lloyd's relax iterations:
• Pattern width : Width of the area filled with cells
• Pattern height : Height of the area filled with cells
• % to scale cells (10-100) : Percentage to scale down each of the cells

3. Click OK to generate the sketch

Note that a large number (> 128) of cells may take a while to generate (sometimes several minutes).

Once the voronoi sketch is created I will usually project the geometry onto a surface and then modify from there. Note that projecting onto a curved surface will not work at this time. In this case I'll use push/pull on the voronoi geometry to modify existing models. The image above was created using this method and a 128 cell voronoi pattern.

Examples posted on my Fusion 360 project gallery.

• One cell may not be filled after generation. Adjusting a control point then forces it to fill.
• It's not possible to adjust the spline's knots and strengths therefore the curves don't conform as close as they should. The "% Scale Cell" value is a workaround for this. Scaling down the cells reduces the possible overlap of the cells.

This code makes use of the Raymond Hill's well done Javascript-Voronoi code: https://github.com/gorhill/Javascript-Voronoi

Github user LeonFedotov kindly submitted the changes to support Lloyd's relaxation algorithm. More information about the algorithm on Wikipedia.
