@z3dev yeah, I went 'custom' way before I found JSCAD, I began by exposing VerbNurbs library first and implemented BabylonJS rendering but JSCAD adds so much to the project that I'm super enthusiastic about it. Vue part sounds very interesting. While I'm not very familiar with Vue, I suppose by reactive you mean Rxjs kind of reactive? Will have to analyse your project in more detail, thanks!
