Pete Johanson@mntmn if you're exploring and haven't tried it yet, give #build123d a try as well. Should work in CQ Editor.
Michael J. GrattonCAD-as-code (and maybe CAD people in general) people, newbie question for you:
Where do you typically put the origin of simple parts such that will be combined into larger assemblies?
Geometric centre? Pick a corner and grow everything in positive x, y, z? Something else?
I ask because the centre seems to me like the most general approach, but then you're having to constantly be moving parts around, typically by doing a lot of floating point division (which is terribly imprecise), like halving dimensions all the time to keep them centred. And then when centred, you have to shuffle them again by a bunch of half-as-muches to build them into assemblies.
But OTOH, having the origin off in some random corner seems somewhat pyrrhic also.
Thoughts? Feelings? Comments?
Hackerspace TrójmiastoJest taka akcja że na najbliższym #PyDataTrójmiasto wystąpi nasza Marta Sienkiewicz by opowiedzieć jak #Python może pomóc w modelowaniu miast (jeśli zatrudnimy do tego bibliotekę #build123d i dane z #OpenStreetMap .
Niektórzy mogli już widzieć zajawkę na #PyGda -- przygotujcie się że będzie jeszcze lepiej!
s-oltaking the chance to re-implement the whole CAD file in #build123d instead of cadquery (https://build123d.readthedocs.io/). It's quite some effort but coming out a lot more readable, which means more editable, which is what I need right now as I tweak it and experiment with things like a possible "fully closed shell" design.
Thanks again @alderwick for the suggestion on how to solve the design dilemma! I haven't cut the USB-hole yet as you can see, but the spot is reserved ;)
C.I have released version 0.9 of `cq-studio`, my hot-reloading server for using the excellent #YACV viewer to interact with models you build in #CadQuery (or #build123d) with #Python code, programmatically. It lets you edit your model code module(s) in any editor/IDE you like, and the models are re-rendered whenever changes to your files are saved.
https://pypi.org/project/cq-studio/
You can install it with just `pipx install cq-studio`. If you've never used pipx before, it requires a tiny amount of setup to add the programs it installs to your file search PATH environment variable.
CadQuery is an alternative to the perhaps better-known OpenSCAD package. CadQuery uses a more advanced CAD kernel than OpenSCAD, but they both have their uses.

Well, so I just published my first-in-a-long-time brand-new #OpenSource / #FreeSoftware project. And I decided it was finally time to get a #PyPI account, so it actually shows up there.
It's `cq-studio`:

It's to use with #CadQuery (or #build123d, perhaps), a way to #model #3D objects programmatically, with #Python code. You edit your code in whatever editor, and view the results with a great interactive viewer in your browser.
