Updraw vs TouchDraw 2

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

TouchDraw 2 brings the power of vector drawing and diagramming to your iPad and iPhone with an interface that's easy to learn and satisfying to master. Whether you're sketching out ideas, diagramming a process, or drafting a technical layout, TouchDraw gives you the flexibility to work quickly and precisely, without unnecessary complexity. From the first tap, TouchDraw 2 feels intuitive. Use familiar multi-touch gestures and Apple Pencil to draw shapes and lines naturally. Smart guides, snap-to-grid tools, and shape recognition help beginners create polished results, while more advanced users can take advantage of layers, dimension lines, and connectors that stay intelligently linked as you move elements. TouchDraw is perfect for countless scenarios—flowcharts, floor plans, mind maps, technical drawings, illustrations, and more. It adapts to your needs without locking you into a specific workflow.
