The term “workflow” gets thrown around a lot these days. For example, say you own a 3D printer and you just came up with an idea. The temptation is to go straight to your favorite CAD tool, start designing the finished product, and then hit print. That, in many cases, can be the worst thing you could do. You would be missing out on all the variation and design choices you can easily try out with a simple series of drawings.
So, you’ve worked out your drawing, played with the design a bit, and now it is time to design in 3D on the computer right? Not so fast. Depending on the nature of the design, you might want to follow this nice tutorial from [Willy Nicholas] on how to quickly make a cardboard prototype.
Now, obviously this won’t work on all designs. But it’s a tool everyone should keep in their bag of tricks. It allows for basically free, quick mock ups that you can hold in your hand. That last bit is important, because having something you can touch and see is a huge part of the design process.
You can also use cardboard as an excellent device for making templates for working with materials such as sheet metal. In case you have seen it, check out “Project Binky” to see what a couple of blokes in England are able to accomplish with nothing much more than a welder, a grinder and some cardboard.
