> That’s exactly my take. What exactly constitutes a “derived work” in the gpl (plug-ins do!) Of course they do. The goal of GPL is to reduce the amount of proprietary software in the world. Proprietary plug-ins would go directly against this.

The result of GPL is reducing the amount of GPL in the world.

Exactly. I love the irony of "forced openness" :p

> It's totally legal. If the IPC is here only for the sake of circumventing the GPL (e.g. there aren't any meaningful use of the "GPL plug-in" part through this IPC channel outside of communication with the non-GPL program), it's totally not. What are such plug-ins ?

IPC is totally worthwhile for native applications in any case, when separate complex components are combined into a single user session. Running the code in separate heaps reduces the chances of bugs in one application code corrupting the entire application heap. Very hard to argue that IPC would ever be just for avoiding license. It always increases total robustness.

I agree with you -- it's hard to safely kill a runaway thread but it's not hard to kill a runaway process. But I think it's worth noting that the performance characteristics of IPC can be very bad

Do you see any other reasonable options in the intended pricepoint besides OpenCascade?

Parasolid and Acis are the only other options. I have a lot of admiration for OpenCascade but unfortunately its functionality is very limited for my needs. I’m considering parasolid but, no, I can’t keep this price point with it

I think it's fine for people to have varying philosophical takes on what should be the normative goals of open source software licenses. Obviously the FSF takes a rather maximalist stance. I personally find this aggressive goal and some of the personalities behind it to not match my vibe. And the reality is that more permissive licenses like MIT are becoming more and more popular. What I've seen some Blender plugins…

Why would it be illegal to use IPC to communicate from one GPL executable to another non GPL executable?

Files are interprocess communication too. If files are fine and other forms are not, then it starts to get into an argument of speed making something illegal.

Not only that, but network communication is IPC and that would imply that it's fine to have a GPL program go to another computer holding a non GPL program, but not if they are on the same computer. There are a lot of holes in this argument.

Not only that, but any program that can't communicate with other programs (do drivers count?) through file formats, networks operations or anything else is probably limited anyway.

Are there parametric features? eg. Can I say "this line is 35mm long"?

I want to emphasize to everyone that this is for concept artists. It’s nurbs used to create interesting shapes and fillets. While there are some parametric features, they’re completely de emphasized compared to something like fusion or solidworks

Some very basic parametric features might open this up to a large woodworking community that wants to sketch out design ideas before building. Sketchup used to be the goto but now people are hungry for a replacement (which seems to be Fusion360 at the moment) but don't want or need a full CAD solution.

Blender supports NURBS. What differentiates this from Blender? Blender is a full fledged pipeline of tools, not to CAD, extensive modeling tools, texturing, rigged animation, post production, multiple rendering engines. It's like comparing a specific photo editor that say focuses on filters and color adjustments, with Photoshop.

In other words, Blender is the Emacs of the 3D world.

it probably deserves the comparison with Linux altogether as it's even more multi purpose and has become, at lead since v2.8, not only appealing to total geeks.

I can't think of any other open source software, other than Linux, that represents such a threat and valid alternative to commercial products. Autodesk be damned, even merging with Adobe wouldn't solve the Blender problem.

Right. It's even got things like a text editor with syntax highlighting and an image editor. If someone spliced a browser in there, it could practically be a whole OS on its own.

The linked page doesn't give a good feel, here's a video from the author that gives a feel for what it's like: https://youtu.be/_yceBZmeW0Q Looks pretty slick, I've been using TinkerCAD for my simple needs, but this looks compelling.

Here's another nice video where the author is doing some more involved modelling, without any talking. It's good at 2x speed.

Even in beta, how you present your work is as important or possibly more important than the "work" itself. (It's actually a significant part of the work.) I've been involved with beta programs for other CAD tools and constantly give feedback to the Onshape team for their design and development of their app. I've worked at major design firms (IDEO, Pentagram, Lunar, etc) and have an ID background. I'm very enthusiasti…

THIS!! I've also been using CAD professionally for nearly two decades (RhinoCAD), and was intrigued by the title. When I saw it was just a GitHub code page, without even much for documentation, etc. My response was basically "nevermind", although I did come to check the comments - the video definitely highlights capabilities in a way I would never have guessed form the GH link. In short, some basics that I learned wh…

It hasn't even launched. It just got submitted to HN by some rando, not the dev.
