which I find a little less confusing than the traditional 3D CAD packages I've tried (and failed to learn) --- at least for Dune 3D I've made it through the tutorial successfully.
Respectfully, I disagree. Even adults have used the word "fun" to describe using solvespace. But I don't actually have feedback from kids, hence the question to OP.
Not saying any of this is easy — Shapr3D on an iPad, expensive and marketed on its extraordinary usability, is just utterly perplexing!
Oh, I actually hate trying to use solvespace with anything other than a 3-button mouse. Unfortunate because the web version can actually run on my phone but is unusable in practice.
I've not used a three button mouse in thirty years. Probably only used a mouse for a dozen hours in the last 15 years.
