It’s software cad. You write code that makes the 3d model. And then you print the 3d model.

The last “official release” was 2 years ago. But development (and community) is active. You gotta get the nightly builds.

    Just follow the tutorial. IIRC it builds a model car. I was able to get from installing, over following the tutorial, to designing my model in half a day.
