Features & Capabilities

Updraw is a pocket 2D CAD tool that brings familiar geometry to your touch screen. Create points, lines, circles, arcs, and cubic splines, then use a global constraint solver to compute distances, angles, radii, coincidences, and more.

Features include a touch-optimized interface, interactive and manual solver modes to resolve constraint ambiguities, and export options for PDF and PNG.

User Reviews

Updraw is praised as a lightweight, intuitive 2D CAD sketching tool with a simple draw-and-measure workflow, and its no-frills, free or low-cost approach appeals to quick dimensioning on mobile. Reviewers repeatedly highlight its potential and easy entry, including a familiar Onshape-like interface. However, critical show-stoppers recur: a near-absent onboarding and documentation; scale, units, and accurate dimensioning are unreliable; editing is limited (cannot delete lines, shapes deform, constraints hard to access); stability and device compatibility are patchy (crashes and OS/device restrictions); export options are limited (no DXF/PDF). Overall, promising but needs tutorials, robust scaling, and better stability to be practical.

Pros

Intuitive and easy to learn once you figure it out.
No-subscription, no-frills, simple to use on mobile.
Useful for quick 2D CAD with a dimensioning/measurement workflow.
Handy as a portable sketching/dimensioning tool; can import to other apps.
Promising potential with a simple design that could improve with updates.

Cons

Lack of onboarding/tutorials and documentation; minimal guidance.
Scale, units, and precise dimensioning are unreliable; cannot reliably draw to scale.
Editing limitations; cannot delete lines, shapes deform, constraints are hard to access.
Stability/compatibility issues; crashes on newer devices/OS and inconsistent support.
Export limitations; no DXF/PDF export and limited export options.

Recent reviews

TONS of potential BUT ZERO INSTRUCTIONS! Figuring out a few things along with some idiosyncrasies, but far from figuring this out for simple 2D drawing. It is clearly parametric but long way to go trying to understand how to use it and export results. It is too bad the author apparently abandoned the app quite some time ago. EDIT: Extremely difficult/almost impossible to pull down constraints menu on ipad. BADLY needs someone somewhere somehow to put up a tutorial or step by step example of use. Bottom line: Dump it

It is beyond basic. No contol over what your drawing, also no scale

Many of the previous reviews dinged this app for being difficult to use, but once I figured it out it was so intuitive and easy. There are basically two tabs, draw and measure. The first step is to draw the rough shape. Then move over to the measure/constrain tab. The key here is to have selected what points or lines you want to measure/constrain and then press the appropriate button. Then make sure to deselect!
