Voronoi Sketch Gen - Settings.png
I've created a small Fusion 360 script for generating Voronoi patterns. When run, the patterns are generated as either straight edged polygons or closed splines within a sketch. These can then be used for creating or modifying bodies.
The flat sample model shown in the images was created using the Model->Sketch->Project/Include->Project to Surface command. The voronoi curves were projected onto one side of the flat surface. The projected curves were then used to cut the model.
For the cylinder and rounded cube it was a bit more work. The Project to Surface command does not work with curved surfaces. Instead, I created construction planes oriented along the side of the model I wanted to apply the pattern. For example, I created 4 planes around the cylinder. The should be done before creating the voronoi sketches since they must be moved using the "Redefine" command. This command requires selecting a plane to move the sketch to and if the plane was created after then it will not be selectable. Phew. Ok, so I created the four construction planes then generated 4 voronoi sketches. I then used the Sketch->Redefine command to move and align each of the voronoi sketches. At that point, for each voronoi sketch, I used the Modify->Press/Pull command to cut the model with the sketch curves.
You may download the script from here:
Also, you might be interested in my Wrap Sketch add-in which makes it easier to wrap a voronoi onto a cylindrical surface:
Note: The above wrap sketch script is no longer necessary with the sheet metal support now part of Fusion. Use the wrap/unwrap functionality with a Voronoi pattern on the surface.
