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.


• 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

Amazing app, helps to have CAD experience

The interface for this app is extremely similar to Onshape, so I picked it up fairly quickly. My only complaint is that the constraints button is right on top of the split screen button. Best fix would be allowing the user to customize the location of the menu. If this was changed, it would be 5 stars.

Great little widget for Solidworks (Onshape) users!

If you know how to “sketch” in Solidworks (or Onshape), and always wanted to have a quick little “sketch”-widget at hand you will LOVE this one - and it’s free.

I hated having to pull out my MacBook and fire up SW in bootcamp (or Parallels) just to do some quick dimension-based 2D drafts, just, ugh. But then I stumbled across this App, and it’s awesome. No more paper notes that miss measurements, or are drafted out off proportions, what a little gem!

Too bad this does not support dxf export or at least pdf, I’d pay good money to get that. Seriously, call me on it! You have a patreon or something? I’ll be there, and happy to advance.

Exactly what I needed

Thanks for making a no-frills, no subscription constrained drawing app. I’d have paid a few bucks for this. UI isn’t perfect and there’s some gotchas to get over but overall does the job. It works great drawing the dimensions in this and then importing into other apps like Concepts to add details, colors, etc.
