Updraw 2.1.1

Updraw is a 2D CAD tool for your Mac. The application allows you to draw familiar shapes and add constraints to solve for unknown distances and angles. It comes with an intuitive interface designed specifically for 2D CAD constraint solving. The utility provides familiar 2D geometry: points, lines, circles, arcs, and cubic splines. Also, it solves global constraint calculations, including distance, diameter, radius, coincident, parallel, perpendicular, angle, congruence, intersection, midpoint, symmetric, and tangent (line to arc, line to spline, circles and arcs).
