OpenSCAD is a Code-CAD, which means models are made from a code script rather than from a series of clicks in a user interface. If you want an un-bias opinion on if this is a good paradigm you'll have to look elsewhere because we/CadHub are massive advocates for it.
A quick run down is that you get all the benifits of git version control. It makes reusing cad logic with a team much easier, and if you think of CAD models as a communication medium between colleagues and machines, what better way of storing it than in an auditable script.
We're going to learn OpenSCAD now over the alternatives because not only is it very mature and stable, it's also easy to pick up. Let's get started!
