Okay, but unless you choose to download the Windows executable, compiling from source is very difficult. Many people won't accept the Snap option on an otherwise open-source platform. This project improves on SolveSpace, but it does this by requiring dozens of mutually conflicting libraries.

There is a flatpak https://flathub.org/en/apps/org.dune3d.dune3d

Thanks -- I missed this. If it pans out, it might get me to shift away from SolveSpace, which has a few perpetually annoying quirks.

Dune3d comes off like a reskin of SolveSpace. SolveSpace is pretty awesome, so that's not a knock, per se. I'll leave it to somebody with more experience to fill in what value Dune3D adds beyond SolveSpace.

I found the UI far more approachable in Dune 3D than any other 3D CAD program I've tried and as the readme notes, Dune 3D imports STEP files and does fillets/chamfers which SolveSpace does not (in the current version) There was a recent video on it: https://www.youtube.com/watch?v=T1VNpC0nwF4 If someone knows of a general introduction to 3D CAD which focuses on vendor-neutral descriptions of terminology and concepts,…

> If someone knows of a general introduction to 3D CAD which focuses on vendor-neutral descriptions of terminology and concepts, I'd be very interested

I'm not sure there is such a thing. Maybe a drafting book would be a vendor neutral description of spec'ing a 3D manufacturable object on a 2D surface.

Otherwise the way the software accomplishes the task is kinda the point which will necessarily have methodology specific terms in it.

Regarding the last point in his FAQ: Ofc. Let's reinvent the wheel, b/c improving the existing SW would be "too much effort", and btw NIH. Doofus.

" Hello everybody out there using minix -

  I'm doing a (free) operating system (just a hobby, won't be big and
  professional like gnu) for 386(486) AT clones."
What's that guy thinking... Doofus.

Second reply -- if anyone wants to run Dune3D, flatpak or compiled, they must set this flag in advance:

export GDK_DEBUG="gl-prefer-gl"

I discovered this while trying out the compiled version (it's essential for the program to run at all), and for some reason I thought the FlatPak install would have done away with this oddity.

Again, because my students aren't necessarily techies, this kind of hacking shouldn't exist in a program released to mere mortals.

But thanks again for alerting me to this release version.

3dDune is actually pretty capable and simple for basic usecases. Plasticity for free form hard surface CAD modeling. If you need parametric CAD then the learning curve jumps significantly and FreeCAD nowdays actually makes sense as with a bit of practice and customization you get to great place.

I don't really do simple designs, and making them parametric would be really difficult. I'm just more visually oriented than mathematical. But yeah FreeCAD I just can't get my head around it right now.

Autodesk making Fusion worse in any way could be the catalyst for FreeCAD to realize its full potential

There is quite a bit more competition though. For example OnShape is imho sweetspot and it's also kinda free.

It's by the team that did Horizon EDA, which is very much a "craftsmanship-first" effort. and they've been working on this for some time now. My guess is hardly any.

Is it a team really? Most commits seem to come from one user "carrotindustries". I am really interested in an Open Source CAD application with good UX, this one looks great. But I don't want to spend too much time on an application maintained mostly by a single developer. The risk of it being abandoned is too high.

As opposed to what?

Autodesk cogitating on what feature they can next do a rug-pull on?

The source is available, worst-case scenario is one puts together the money to hire a developer to fix or improve at need.

The main things Dune3D has over solvespace are 1 - the ability to include STEP files in assemblies, and 2 - the ability to put a chamfer or fillet on the top/bottom of an extrusion. I don't think it has the ability to select arbitrary edges and apply such features (I could be wrong). Solvespace 3.2 is essentially done (try the latest edge build), we just need to get github to produce the correct artifacts (not sure w…

That's actually how it works. Chamfers and fillets are handled by OpenCascade, so they can be applied to arbitrary edges. They only exist on the solid model though, so they are not integrated with the solver.

I'd be curious to see how native chamfers/fillets in solvespace would work, I imagine some amazing things could be done if they'd be part of the solver.

Hmm interesting but no free option for hobbyists (just 30 days). That's a bit of a dealbreaker for me. Looks like a good tool though.

The price is a lot lower than Fusion but still too high for hobby use IMO.
