That one line becomes a real A2 engineering sheet: a section through the mechanism, details at a larger scale, true dimensions, numbered balloons, a parts list and a title block. Then **the parts move**, the dimensions re-measure themselves, and every number on the sheet comes from one physical model. Ask for `3d` and you also get a cutaway you can turn, cut open and take apart.

Who it's for

Engineering students and educators Explore mechanisms, forces, pressure, motion and thermodynamic cycles interactively: real sections, real dimensions, physics you can push. Boyle's law, the Otto cycle, Pascal's principle, pump curves, feedback control.
Developers Understand abstract software concepts as machines: rate limiting is a cistern, back-pressure a relief valve, aut
