I am not a design draftsman, I'm not an engineer. My workflow is usually: I put something on the scanner, load the calibrated scan, trace the outline, throw a few sketches on various planes in there, round a few edges, print it and I'm done....
I think the guide I did at !cad is still in pretty decent shape.
I actually settled on Alibre Design. Permanent license at half the cost of a year of OnShape for a slightly dated but very capable parametric modeler, and the free trial made Parametric modeling click for me in a way FreeCAD didn't. It comes with a renderer of a similar class, though I haven't tried that yet. Changing colors of parts has been enough for my needs.
FreeCAD has apparently fixed the topological naming issue, one of the big things that was keeping them so far behind the commercial suites. It's already in the weekly builds, along with several other enhancements pioneered in the Realthunder fork, including UI enhancements and a default Assembly workbench. Version 1 is going to come out in the late summer or early fall, I think. Ondsel is FreeCAD but they have some venture funding to pay developers to work on the main project and to bolt-on an optional paid PDM system (download from their GitHub and you don't have to sign up for anything). I had some crashing issues on both Windows and Linux when trying to import DXF files into either flavor, and as you say, there's still that learning curve, but I can get a part done in it now if I need to.
SolveSpace can do some nice things and will teach you good techniques.
I had the same issues as you with OnShape, particularly since their free licensing is very weird, and in the worst case it implies that while YOU must use your designs non-commercially, no one else is similarly bound. It's sloppy legal drafting, and that annoys the little black kernel of lawyerness still sunk down in my heart. Fusion has become the poster child for free feature erosion and price hikes.
BricsCAD Shape is a basically an AutoCAD clone warped and twisted to act like SketchUp, and it works on Linux. It's meant to be the tease to get people into their full-suite ecosystem, but I couldn't find any legal limitations on the free version.
Depending on what it is you're scanning, the people mentioning Blender may have a good point.
Shapr3D at $300/year might also be a good option.
Finally, for your particular workflow, Plasticity at $150 permanent license may hit the exact sweet spot. Definitely try their free trial. Some of the other programs I tried are also interesting.
I've made a large number of custom prints, and all of them were created using TinkerCad. It's an amazing toolkit, stupid easy to use but versatile. That is ... until something needs a tiny adjustment somewhere. That's when I feel it would've been neat to use parametric CAD instead....
First, a little plug for !cad because more traffic is welcome. The pinned post there is a fairly comprehensive list of viable 3D mechanical CAD suites. I'm a rank amateur with actual designing, but if you want someone to drone on at length about their business models and licensing terms, I'm your guy. (short version: "Fuck you, fuck you, fuck you, you're cool, and fuck you.")
Now then... I also came from TinkerCAD, and I actually think the grouping and alignment tools lifted from vector art programs are super intuitive, and they almost provide a sort of design history if you use them right, but there are so many things that can't be done quickly in TinkerCAD, and Autodesk also nerfs it for reasons that are commercially sensible but not technically necessary.
Almost all parametric tools , and also most "grown up" (for lack of a better term) direct modeling tools can do the Boolean addition and subtraction that is at the heart of TinkerCAD's "solids'n'holes" paradigm, often in a couple of different ways. For instance, to make your orange part there, I'd draw a 2D silhouette of the vertical view, then extrude (or "pad" or "pull") to the height. Then I'd draw on that top surface, possibly with a reference plane set up first to avoid having the model too far up its own ass (i.e. the toponaming issue), making the shape that needs to be extracted. Then you can cut or extrude down into your solid. Most tools will know what you mean, but some might make you do use a distionct tool or manually do the boolean "difference". You can then do the same with your hex grid, setting up a new sketch for that. Later, if (for instance) you wanted to have 12 holes or bigger holes, you'd just edit the one sketch. Your red part would be similar, but doing the back of it would involve extruding out from the new sketch. The power of sketch and extrude is, apart from the ease of implementing a parametric history, doing several things at one that would each have to be a manual hole in TinkerCAD.
Finally, there's the simple matter of fillets and chamfers, which TinkerCAD doesn't support as an independent function. Manually adding them gets tiresome real quick and is the "killer feature" that made me realize I needed to move on. Other tools like loft sealed the deal. TinkerCAD is capable of some really interesting parts, but not efficiently.
I liked Fusion 360, I like Onshape - but I'd rather like something that I won't lose over the whims of one company. So, what?
