Here's an example! I recently used their sister library (build123d, same devs) to build a rotary slide rule bracelet for multiplying three-digit numbers. It was a great experience and wouldn't generally be easy to do with Fusion 360. My bracelet gets quite a lot of comments when I wear it in public. :-) Here's an IPython notebook with lots of pictures so you can see how the different operations come together: https:/…

Interesting. I have played with OpenScad a bit. This looks similar - i guess the difference is the syntax is python - any other major differences
OpenSCAD is all triangles and vertices. Fillets are difficult to do. Outputting circles/spheres generally requires you to for-loop over vertices a lot. Libraries like build123d and cadquery use OpenCASCADE, a boundary representation kernel. You think in terms of the enclosed solid and perform operations - boolean add/subtract, fillet/chamfer, stamp text, etc - that return a new solid.

how does it work? (the multiplication)
This method was widely used in the pre-computer era to save time in calculations. Tables of logarithms (and slide rules) were a mathematician's best friend.

I'm not sure I understand your comment; OpenSCAD has functions like sphere(), cylinder(), etc. Most OpenSCAD models I have seen are built up primarily from solid primitives combined using boolean operations, just as you describe for the other tools. https://en.wikibooks.org/w/index.php?title=OpenSCAD_User_Man...
Some of the differences may be in when you are trying to reference a face/edge to build off of, not just about the primitive function being used.
Anyone has used it?

These libraries on the other hand can natively represent a sphere for instance. This means that during CAD-ing you don't need to worry about resolution, that's a consideration for export only.

CadQuery can export STEP files, and is overall much nicer to use in my opinion.
