  • Great new free CAD program

    I'm doing some design work for my next set of DIYs, and since they're going to be a trans-lam build I figured I should learn some CAD in the process. I've always hated SketchUp, I don't have the patience to learn the heavy-duty free CAD programs, and I don't have the money for some of the better commercial software.

    Yesterday I came across OnShape, and so far it has been outstanding. In just a few hours I was able to figure out how to make this:


    ...Which is much further than I ever managed to get in Sketchup. Obviously this model is missing some features and is kind of rough around the edges, but for never having been able to make a model like this before I'm really happy with how painless it was.

    It is totally free for personal use, it is cloud-based so the computation is all handled by servers off in a datacenter somewhere and not on your laptop, and it is quite powerful. You can also export the files for each part in standard CAD formats. Each part can be made separately, and assemblies can be defined with mating surfaces. It is probably missing some of the high-end features you'd find in Autodesk (tolerances, material properties, etc.) but that hardly matters when you're just going to be plowing shapes out of MDF with a router.

    Just thought I'd put a mention of it out here, since I hadn't heard of it yet and I know people are always asking around for this sort of thing. It requires a beta invite, but I requested one yesterday and it came in just a couple of hours.

    Pretty cool. Thanks

        Kind of off topic, but your layout looks a lot like this epic build:

        It's a long thread, but it might be worth skimming to see some of the highlights.

          DraftSight by Solidworks is a free download. It looks and operates EXACTLY like AutoCAD, even the icons are the same.

            Wow, nice find. I thought I'd seen all of the good trans-lam builds out there, but I hadn't come across this one yet. Thanks!

            Fortunately I do have access to a 4'x8' CNC machine for the wood parts, and I am also going to be cutting the front baffle from metal and I can use a CNC machine for that as well.
