Rhino is a 3d design program which allows you to create 3d objects in a non-material setting. This could save time and expense on materials (though the program is quite expensive in itself) and can help give a visualisation for something that you are making. Conversely, it could be something you intend to 3d print, usually on a smallish scale, as it is a very time consuming process.
Adobe Illustrator can be used for many things, but in our case we will be using it for the purpose of lineart for the laser cutter. This will be very useful to me as I’m sure i will be using this in the near future.
