![]() ![]() The guys who use Sketchup routinely use programs like Netfabb to repair the STL files so they can print them. That makes certain operations difficult or impossible to do and results in all those holes and overlaps. The STL files are usually full of holes and overlaps because curves are not represented as curves internally- they are always polygons. It is easy to learn and use, but not very good for designing parts for 3D printing. I've used it, and it takes some effort to learn it, but it does everything. None of it is crippled- you get the full Monty, but limited storage for your projects on their servers unless you pay a little. I think it is a subscription service with some very low cost or even free entry points. You can do 3D CAD from any screen that has an internet connection because their servers do all the heavy lifting. The guys who wrote Solidworks have a new, similar product called OnShape which is cloud-based CAD. It's a freebie, too, but naturally, they leave out a few features in hopes of upselling you to the professional package called SpaceClaim. I have been using it for about 2 years to design all sorts of stuff and rarely run into its limitations. Also free, but very easy to learn yet reasonably powerful. It is free for non commercial use (for at least a year).Īt the other end of the spectrum is DesignSpark Mechanical. If you don't mind a bit of work to get up to speed on a professional level package, try Autodesk Fusion 360. It sort of depends on how much effort you're willing to invest in learning the software. ![]()
