Wow that's cool!

New release of build123d dropped earlier today! Huge new functionality including better surface modeling features github.com/gumyr/build1...

I typically just apply the sauce immediately before putting in oven, works great for me!

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.

Sick, love BREP

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...

They are both great communities and focused on learning and developing new skills! They both have discord channels which is where a lot of the activity takes place.

How many of these shirts do you own? Honestly I wouldn't be surprised if you had one stashed everywhere given the frequency of these outages...

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

Live now!
Open Source Hardware Association (OSHWA) is doing a Show and Tell 12 hour Membership Drive with creators from all over joining us to show off their work! @oshwassociation.bsky.social www.youtube.com/watch?v=Yn0e...

poster for the 12hr livestream featuring text and a computer with the gear logo on the screen over a circuit line text reads " open hardware month october 6 8am-8pm 12 hour livestream!"

It's almost October which means it's almost Open Hardware Month! Mark your calendars and get excited because there's going to be really amazing speakers and perhaps even some sloths during our 12hr membership livestream! How are you celebrating Open Hardware Month?

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

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:

Here's my first attempt at the square, I think should be generalizable to all regular polygons fairly easily but need to think on it a bit. 1D are first class citizens in build123d, which makes this quite a bit easier

Hmm, is there a rule defining the orientation/angle of the arc at the e.g. square corner?

How about this? I made a few improvements since my last post. I also fused the hexagons together and then offset them to create some tolerance to allow for a better fit. The tolerance I used is quite high just to make it visually obvious.

Wondering if build123d could work for you? I watched your video and came up with this approach using construction geometry that act as helpers to place hexagons. This approach should scale very well to more complex hexagonal tilings.

Ah, didn't realize you had your own implementation of Minkowski! Nice progress for sure

Nice, how fast is minkowski these days?

Do you have any thoughts on the app signing requirements that are becoming more and more mandatory?

It's even worse than it seems because the most popular CAD packages use just a handful of CAD kernels. The prices of these CAD packages simply can't go below a certain number due to the cost of licensing the kernel. The Plasticity dev has talked at length about this on YT.

FYI SW for makers creates files that cannot be opened by regular SW.
