Openscad gear library2/28/2024 It turns out there is something very similar in the circuit simulator for that purpose. You might assume that is a way to program the Arduinos in the simulation, but that’s not what it is. One is Circuits which lets you build and simulate simple electronic circuits that include Arduinos and other items. When you go to the Tinkercad website, you probably notice there are two extra selections in addition to 3D design. But if you have the math defining it right, you change a few variables, and the computer does the rest. But if you later decide the top row needs five holes and the bottom only needs three, it will be a fair amount of work. As an example, suppose you have a front panel with two rows of four holes for switches evenly spaced and centered. This is, of course, a simple form of it, but the idea is to define things as mathematical relationships. If you’ve used parametric design in a professional package or even used something like OpenSCAD, you probably don’t need to be sold on the benefit. However, they replaced it with Codeblocks which is much easier to use for their target audience - young students - and still very powerful. There was a time when you could write Javascript to create custom shapes, and it is true that they removed that feature. Codeblocks allow you to easily create custom parametric items for use in Tinkercad. However, I heard someone complaining the other day that it wasn’t of any use anymore because they took away custom shape generators. While I use a number of CAD programs for serious work, sometimes, when I just want a little widget like a flange for my laser cutter’s exhaust, it is just easier to do it in a few minutes with Tinkercad. You hate to admit you use it, and you know you should put in more effort, but - darn it - it’s easy, and it tastes pretty good. Tinkercad is like the hamburger helper of 3D design.
