What I really want to try is the `ty` plugin which acts as LSP, hopefully faster than the standard one

About β€” build123d 0.10.1.dev166+g86ab032cb documentation

For OpenSCAD, sadly I do not as I stopped using it quite a few years ago. For build123d I recommend the docs build123d.readthedocs.io/en/latest/.

OpenSCAD is worth a shot for sure, but definitely use the nightly builds -- they are more stable and feature rich. Also check out build123d, it is kind of like OpenSCAD but you get native fillets / chamfers.

Perhaps store bought is terrible, but homemade it is honestly my overall favorite pasta sauce

Walmart dishwasher powder costs 6.6 cents/ounce, Great Value pods cost 26.9 cents/ounce, Cascade Platinum pods cost 73.8 cents/ounce. The price difference is enormous! (used pricing from walmart website)

It's very similar IMHO to Keurig, pre-dosed bad coffee with a high cost in the name of "convenience". Drip coffee with a paper filter that can be composted is plenty convenient for me -- while being cheaper and higher quality.

Nellie's dishwasher powder is the right intersection of cheap enough, good performance, short ingredient list, and reputable source for me.

Took a stab in build123d, definitely non-trivial!

Yep, you can use e.g. the `location_at` operator (shortcut ^) on edges or faces and it will give you info about both location and orientation. It works a bit differently from BOSL2 but the same info is available. Here is a super simple demo, but the same idea scales to any shape of arbitrary form.

Yes do it!! (Or at least give it a try to see if you like it) FYI there is also webasm build123d now too!! e. g. jojain.github.io/build123d-sa...

Have you considered build123d? In short it combines benefits of OpenSCAD with benefits of BREP CAD like Fusion.

Cheat Sheet β€” build123d 0.1.dev194+g0166408f6 documentation

See the [build123d cheatsheet](build123d.readthedocs.io/en/latest/ch...) for further information about available arc types (supports hovering to see doc string). 3/3

Assumption 1 is described above. Assumption 2 is that the arc starts at an angle perpendicular to an axis passing through the regular polygon center. For that build123d's `TangentArc` was a good choice, however it may also be possible to use `RadiusArc` which accepts two points and a radius. 2/3

02.10.2025 15:21 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

No, I simply set the point at which the arc would terminate. The resulting radii are different for each regular polygon. There are a number of approaches here that would work. The correct way to formalize this is a technical drawing, but given the lack of that I had to make some assumptions. 1/2

Nice, yes OpenSCAD also supports 2D offsets -- so that is probably a good idea here.

Awesome, glad to hear I understood your goal better this time! This is python, yes. build123d supports exporting to a wide range of 3D formats; STL, 3MF, GLTF, STEP, and BREP.

OK, I generalized it and it now works for even and odd regular polygons. FYI, It is also totally possible to use various transformations to turn these 1D objects into 3D solids (not demonstrated here). Quick and dirty video demo + code:
