In order to use Guides, you will first need to enable Rulers on your canvas.
You can do this with the Shift + R keyboard shortcut, or by clicking the menu icon in the upper left corner of the Editor and searching for “Rulers”.
Click and drag on the horizontal and vertical rulers to pull guides onto your canvas.
The dotted line acts as visual indicator that your guide is intersecting with a frame on the canvas.
Viewing Distances (Redlines):
With a top level frame selected, hold Option (on Mac) or Control (on Windows) as you click and drag out a guide. You will see the distance (in pixels) between your guide and the frame. This distance is also reflected in the ruler. When the guide intersects your frame it will begin measuring distances between the guide and objects in the frame.
In addition, with a frame selected the rulers highlight in blue, calling attention to the coordinates of the frame on your canvas. When you select objects in the frame, you'll see the same blue highlights for the selected object.
Guides inside frames are recognized as another object in the frame. This means you can view redline distances between the guide itself and other elements in the frame, as well as the parent frame.
In addition to clicking and dragging the guide back to the rulers, you can also:
- Hover over the guide to reveal the double-sided arrow
- Single click (the guide will turn blue)
- Use Delete on your keyboard to remove the guide
