Updraw - create 2D CAD drawings with dimensions

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

Features:

• Intuitive interface designed specifically for touch screens
• 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
