I've made a bunch of stuff in OpenSCAD and it can be really nice to work with but... it does have a bunch of weirdnesses like not being to find the size of a compound object, having to micro-manage your objects to avoid the spinning beach ball render, fillets/chamfers/rounded edges/etc. are dark arts, etc.

If you're basically sticking simple shapes together or cutting simple shapes out of other shapes, it's fine enough.

Yeah, it has its charms but... Good luck making a filet or a chamfer between two faces whose intersection has a non-trivial placement.

Being able to easily reference existing edges and faces for future operations is one of the things that make other CAD so simple.

the "manifold" renderer makes possible some stunts that couldn't be done before. for example, i made this "usa counties" outline from a png: https://www.printables.com/model/895723-usa-counties

its under the "features" preference, doesn't work for everything yet, but is worth investigating if you haven't.

OpenSCAD has been great for simple projects. It’s very easy to get productive with if you know basic programming concepts. However, I’ve run into frustrating limitations on more complex projects. The core geometry engine is skittish.

I still use OpenSCAD, but I’m diving into the OCCT ecosystem. It has a steeper learning curve, but seems to be significantly more robust.
