Updraw is the 2D CAD tool you've always wanted for your mac! It allows you to draw familiar shapes and add constraints to solve for unknown distances and angles.

Features:

• Intuitive interface designed specifically for 2D CAD constraint solving
• Familiar 2D geometry: points, lines, circles, arcs, and cubic splines
• Global constraint solver calculations: distance, diameter, radius, coincident, parallel, perpendicular, angle, congruence, intersection, midpoint, symmetric, and tangent (line to arc, line to spline, circles and arcs)
• Interactive and manual solver modes help to resolve constraint ambiguities
• PDF and PNG image export

Release notes:
• New "Input" preference to customize key modifiers
• Fixed label offset in exported documents
• Fixed retina DPI when switching between GPU and software rendering
