   Q12 – A constraint-based 2D drawing tool▲7

   Q12 is a new web-based 2D parametric drawing tool built specifically for geometric problem solving, for playing interactive "what if" games with drawings, and for the design and optimization of mechanisms. Q12 has the usual set of drawing constraints found in other CAD tools (e.g. "lines are parallel") but also supports inequality constraints, area constraints, and arbitrary expressions between geometric quantities. We built Q12 to solve problems like those below, after finding that existing CAD systems couldn't handle them well: * Given dimensions on a surveyor's map, figure out if the…
