How to Get Started with the Super Ruler

Step 1. Measure & Draw

Tap the Super Ruler button to show the Super Ruler. Then, you can use it to draw straight lines along its edge. You can also measure distances with the ruler. When you zoom in and out, you'll see that the units adjust to give you the best measurements at any view.

Pro Tip
Rotate the ruler three times to get an angle less than 3°.

Step 2. Straight Lines with Angle Snap

To draw straight lines anywhere in your drawing space without realigning the ruler, tap the Gear button and then turn "Assist" on. Next, select your Snap Angle. You can choose between 15º, 30º, 45º, or 90º. Take note that the snap angle will adjust to the rotation of your ruler.
