And the answer is... I'm broke 😌
I was treating the center({axes:[true, true, false]}, object) like the old object({center:[true,true,false]}) which is not the case since primitives are now created centered at [0,0,0] by default.
Since the primitive is created centered by default at [0,0,0], changing the axes on a new part doesn't really have an effect.
Picking a consistent default is probably the 'right thing(tm)' to do since the old primitives where very inconsistent - round things like cylinders and sphere where centered on X/Y but not Z and cubes where created with a corner at [0,0,0].
Hopefully new docs will have little warnings for those transitioning from V1 to V2 and maybe some helpful examples for porting old designs over.

There have been several discussions about how to build transitions between shapes. Hull and Minkowski are good at combining shapes but don't really provide the workflow described here.

Here's one from a while back..

Can we extrude arbitrary and changing 2D shapes along a 2D/3D path?

I would hope that some of the folks here could provide some tips.

@viktor-hedefalk said in Vanilla js/npm in browser?:

Or does it resolve those at upload time? Gonna test that…

No, it can't do that? That would be the worst security thing ever on a browser to allow…

Just watched the tutorial series to the end of part 4 - and the cliffhanger for part 5:

"In the next part we will get to how you can split up your design into multiple files…" 🙂

Thank you for applying for Maker Faire Tokyo 2019.
We are glad to notice that your exhibit is accepted.

We are looking forward to meeting you in Tokyo!*

So, it’s now official! 🙂
Let me know if anyone wants to attend.

You might want to post your question on stackoverflow https://stackoverflow.com/questions/tagged/openjscad - the audience is bigger there.

OK. I archived what I could down load using the crappy tools from Google.

I’m pretty peaved at the results. Obviously, Google thinks that a bunch of monkeys can write software to download web content. SIGH

@gilboonet thanks for the links...

When I find some free time, I will definitely dig into it.

Currently, I have too many projects in parallel, to add another fascinating one 🙂
