@gilboonet It works. I needed to specify ... while pushing content into the return variable. I still need to stop the animation so my video capture will perfectly loop. And there's something that I didn't manage to do, it's creating a new project, for the moment I'm changing demo-web.js, otherwise there is an error (cannot find myAnim.js when I try to run npù run myAnim.js) [image: ours342.gif]

Thanks! I'll give it a comment of support there

Thank you so much! Honestly looking at it now I don't see how I didn't understand how it worked. Union takes an array of solids so that would make the most sense. Thanks!

@BarbourSmith I saw your post but didn't reply as I wasn't sure it was about. I already tried on V2 the function that splits a solid into pieces as it is something that i use a lot : https://jscad.xyz/#https://raw.githubusercontent.com/gilboonet/gilboonet.github.io/master/demos/gig2i.js The function is scission3d() and the source is here : https://github.com/gilboonet/gilboonet.github.io/blob/master/demos/gig2i.js

@BarbourSmith is there some reason to use three.js? the primary focus of three.js is quite differnet from JSCAD. It should be pretty trivial to convert between three.js data structures and JSCAD data structures. But don't expect either project to supply the conversions. Maybe somone has a set of functions already, or you'll have to write some simple conversion functions.
