  • CADmium: A Local-First CAD Program Built for the Browser

    Why in a browser if it's local-first?

    Solvespace has the benefit of being a single download/executable.

    It also has a constraint solver which has been used in a couple of projects: CADsketcher as you noted, and Dune 3D: https://github.com/dune3d/dune3d where the author noted:

    >I ended up directly using solvespace's solver instead of the suggested wrapper code since it didn't expose all of the features I needed. I also had to patch the solver to make it sufficiently fast for the kinds of equations I was generating by symbolically solving equations where applicable.

    Any relation to: https://github.com/jay3sh/cadmium ?

    Also, for CAD kernels, Manifold was not mentioned: https://github.com/elalish/manifold/wiki/Manifold-Library --- while I understand it to have many of the same disadvantages as OpenCASCADE, it does seem worth mentioning.

    Interestingly the kernel was previously discussed here:

    https://news.ycombinator.com/item?id=35071317

    It seems really interesting/promising, esp. the compleat history and editability (I'd love to see that history listed in a pane which could be opened/closed --- add a series of disclosure triangles which would allow hiding finished elements so that one could focus on the current task and it would be a dream come true for me --- if I can puzzle out the 3D stuff, so far I've crashed and burned on all the apps I've tried (BRL-CAD, FreeCAD, Solvespace, Alibre Atom...) --- the only thing I've been successful w/ is OpenSCAD and similar coding tools).

    Small in a relative sense compared to some larger codebase.

    Here's a bit on Manifold:

    and the author's blog is interesting:

    Wondering why no BRep support means it is not a CAD. It seems that OpenVSP doesn't use BRep but uses parametric surface [1]. I wonder if mesh-based modeling + some constraints solving will get you a CAD, or are there other requirements that I don't know? I only work on mesh processing library on my free-time and I don't know much about BRep.

  • My Unhealthy Relationship with Keyboards ⌨
    2 projects | news.ycombinator.com | 27 Sep 2023
    Unhealthy relationship with keyboards? Comparing with the r/MechanicalKeyboards or r/ErgoMechKeyboards people this relationship is more like divorced...

    I added python binding and ended up being on of the devs for https://github.com/elalish/manifold because OpenSCAD is too slow for my modeling (I am quite impatient). Optimizing my keyboard for months with more than 5 complete rebuilds to optimize my design (looks like this: https://i.redd.it/xtf0f54mt7ya1.jpg), and is afraid of open sourcing it because my code looks too bad :(

    Now much faster and more stable thanks to the Manifold engine (https://github.com/elalish/manifold): in fact it is often faster than the last stable desktop release from https://openscad.org/.

    Also much better code completion, and ships with a few examples from the various bundled libraries to get you started.

  • When I place down a CSGPolygon3D in this shape (haven't tried other shapes) it always opens a portal to hell, and it's not just in the editor, it's in the game too. Does anyone know what I can do about this?

    At the end, they gonna replace it with ( elalish manifold.
