The great thing about OpenSCAD is that it makes it easy to model objects which may be represented by positioning/stretching/adding/subtracting cubes, spheres, cylinders, and cones using mathematics.

The awful thing about OpenSCAD is what one can model in it is directly limited to ones fluency and facility with using math to position, stretch, add, and subtract cubes, spheres, cylineders, and cones.

There is an entire book series on using it didactically:

- Trigonometry: https://www.goodreads.com/book/show/123127774-make

- Calculus: https://www.goodreads.com/book/show/61739368-make

and there is a new book on Physics: https://www.makershed.com/products/make-physics
