The Rulers

You can draw perfect lines and shapes with the rulers. Open the ruler menu first, you can see lines, a triangle, a circle, and a quadrilateral. Select a ruler that you want to use.

The ruler will appear on the canvas. Place your finger on the dot to rotate or transform the shape.  Use the spread and pinch hand gestures to resize the shape. 

If you wish to exit the ruler mode, please tap “x”.
