It does not support STEP export, unfortunately, because STEP files use a completely different underlying representation.
Most STEP files represent shapes as a set of surfaces (e.g. trimmed NURBS). These surfaces have to form a watertight manifold, which can be treated as a solid volume.
To make this actually work, you need a kernel for boundary representations (b-reps), rather than Fidget's functional representations (f-reps). Writing such a kernel is a much harder problem – as one example, the intersection of two NURBS surfaces doesn't always have a closed-form representation! In conversations with someone in the industry, they estimated it would take 6 engineers about a year to write a decent b-rep kernel, if they had done it before.
If you'd like to learn more, I've coincidentally also written a STEP file viewer, which includes a far-from-industrial-strength b-rep kernel: https://www.mattkeeter.com/projects/foxtrot/ https://www.mattkeeter.com/projects/foxtrot/

- bhaney 2y agoI've been using Studio as my primary way of generating models for 3D printing for years now, no OpenSCAD involved. Write some scheme, get an STL. I do wish Matt would cool it with his constant brilliant endeavors and go back and give Studio some love though. At this point I can't get it to build and can only launch an old version I compiled years ago that breaks if I'm not in some specific working directory in my Downloads folder.
