What Are Your Indispensable Software Skills?

Using tools properly takes skill, and this goes for software tools as well as hardware. You don’t just buy a paintbrush and on day one paint the Mona Lisa. Similarly, you can’t just open up a CAD program and whip out whatever 3D objects your heart desires, or fire up Vim and start typing. Software tools take a bit of learning before you can wield them efficiently, if even at all. And because you can’t be skilled at everything, no matter how hard we are all trying, it’s good to have at least some of the software tools you know do double duty.

Tom and I were watching [Clough42] design an electronics cabinet for a CNC machine. He does a lot of CNC machining and design work, so he’s no stranger to CAD software. So he downloaded all of the parts that he needed inside cabinet, slid them onto virtual DIN rails, modeled the hinges, and made sure that everything fit before buying anything.

Now I know that some of you out there do CAD modeling like this all the time, but for Tom and I, who are 3D printerers and PCB layouterers, doing the CAD without then following through and finishing up with the CAM seemed a bit novel. I never open CAD unless I’m going to have a machine make the thing – otherwise I’d just draw it out on paper, right? But [Clough42]’s point is that getting models of all of the subparts is so easy these days, you might as well model it.

If, and this is the big “if”, you know your way around the CAD tool of your choice. If you don’t yet, it’s going to be a couple of days’ worth of effort to get there. But once you reach CAD nirvana, you’ll find it’s useful for sketching up anything that has a third dimension to it, not just stuff you need to print out.

What other software tools are like CAD in that once you know them well enough, a wealth of applications opens up before you? Of was this just an instance of having a hammer and everything looking like a nail?
