Cuis Smalltalk (https://cuis.st) uses vector graphics for its rendering engine!

Comment · 5 days ago

I would recommend Cuis Smalltalk (https://cuis.st) as a more idiomatic solution that also looks much better due to it's vector graphic based rendering engine.

I've tried to get into Solidworks, Fusion, and FreeCAD several times, but every time I come back to programmatic CAD. It just better matches how I think about 3D design I guess. Also, I love that there can't be any hidden state or constraints -everything is fully defined by your code and fully visible.

Just give it a try, I guess, and see if it works for your use cases!

I was actually able to get a first version released just now: https://luacad.ad-si.com/playground It's still rather bare bones and won't work well for large models, but otherwise it should be fully functional!

I'm pretty sure it's Turing complete by now. If it was conceptualized as a limited language and only became a full fledged programming language over time, it would certainly explain all its weird warts. (Here is some more details: https://github.com/ad-si/LuaCAD#why-lua) I guess 3D modeling is just too complex for a simple, but limited DSL.

Lua is easier to use, faster, and more feature-rich. It's one of those rare occasions when a new solution is actually better in every single way.

Agreed! I’m already working on it, but it’s not quite ready yet. ETA is 1-2 weeks.

Thanks! It natively supports all BOSL2 functions which include a chamfer argument (https://github.com/revarbat/BOSL/wiki#common-arguments). So that makes it quite straightforward to add chamfers to everything!

Yes, it executes in a full fledged Lua environment. So you can do all the things you expect do be able to do with Lua!

I’d pick Lua over Python any day, but maybe that’s just me. ;-)

Good idea! Just committed the necessary changes in https://github.com/ad-si/Woxi/commit/f337a722871ad1b08f8e783.... Did I do it correctly?

No, none of them are implemented yet. I'll bump the priority to implement this!

Interesting - I would never use it as I find entering math with plain ASCII much faster and more intuitive, but if there is interest in this, I'll increase its priority!

Any help is highly appreciated! A great way to get started would be to open issues for the problems you found at https://github.com/ad-si/Woxi/issues.

Thanks! I’m interested as well … I’ll check it out and report back!

Performance is pretty good for most stuff by now. However, there are functions which not optimized yet or implemented in a very basic way and if you use them in non-trivial ways the performance might be quite slow. We're happy about any reports of such issues at https://github.com/ad-si/Woxi/issues!
