Q12 is a web-based 2D drawing tool for makers and engineers. Solve geometric problems with constraints, explore interactive “what if” scenarios, and design mechanisms in real time. It supports advanced constraints including inequalities, area, and arbitrary expressions between geometric quantities. This is the first public release - excited to see what you build with it.

We built Q12 after struggling with existing CAD tools for years. Constraint-based CAD is meant to help solve geometric problems, yet most tools proved to be limiting. Q12 was designed for problems like these: Given an incomplete set of dimensions on a surveyor's map, figure out if the stated land areas might be correct. Reveal which extra measurements are needed to pin things down. In a...
