## What is Updraw?

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

## Key features

- Intuitive touch screen interface
- 2D geometry tools (lines, circles, arcs)
- Global constraint solver
- Interactive and manual solver modes

### 2/5 — May be a hidden Gem - Needs Completion

*2026-05-20, version 2.1.1*

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

### 2/5 — Little control

*2026-01-20, version 2.1.1*

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

### 5/5 — Perfect parametric CAD on the go

*2025-12-17, version 2.1.1*

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!

### 3/5 — No Instructions

*2025-11-30, version 2.1.1*

This would be a nice app and could provide exactly what I need, but there are no instructions on how to use for even the simplest thing. That’s the problem with a lot of these apps. Developers assume you just know what the cacophony of tiny symbols means with no explanation of how to even set up the drawing scale or parameters.

### 1/5 — Вышибает

*2025-11-08, version 2.1.1*

Не работает. Вылетает не открывается.

### 3/5 — App not opening

*2025-10-30, version 2.1.1*

Downloaded app today on my Apple 6thgen newest version 17.7.10 cant open app to create a drawing for a jig to create in my locomotive industry ,, this is putting me in a bad spot cause I need to submit this drawing to the cnc machinist to mill aluminum plates for welding

### 5/5 — Спасибо

*2025-10-08, version 2.1.1*

Программа супер!!!

### 2/5 — Eh

*2025-09-04, version 2.1.1*

Would be okay if my entire drawing wouldn’t deform just by me moving a single shape over to it or tapping the wrong button. Also no place to select units of measurement.

## Frequently asked questions about Updraw

### What can I do with Updraw?

Updraw allows you to create 2D CAD drawings directly on your mobile device. You can draw familiar shapes like lines, circles, and arcs, and then add various constraints to solve for unknown distances and angles within your design.

### What types of constraints does Updraw support?

The app supports a comprehensive set of global constraint solver calculations, including distance, diameter, radius, coincident, parallel, perpendicular, angle, congruence, intersection, midpoint, symmetric, and tangent constraints for lines and arcs.

### How can I save or share my drawings?

Once you have completed your 2D CAD drawing, you can export it as a PDF or PNG image file. This allows you to easily share your designs with others or use them in other applications.

### Is Updraw free to use?

Yes, Updraw is available for free. The application does not have any in-app purchases or advertisements, allowing for an uninterrupted design experience.
