Guidelines are moveable lines which can be used as visual aids during the design process. They are defined by a position and an angle, and are not part of the glyph’s contours.

Guidelines can be of two kinds:

font-level (global)
displayed in all glyphs
glyph-level (local)
displayed in one glyph only

In UFO3, each guideline may also have a color attribute and a unique identifier.

Individual guideline colors are displayed in the Glyph View if available, and can be edited in the Guidelines section of the Inspector panel.

Creating and editing guidelines

To create a new guideline, drag a line from one of the rulers into the Glyph View.

Make sure Rulers and Guides are visible in the Display options.

There are different ways to edit a guideline:

  1. Right-click the guideline to open a contextual menu, and edit the guideline’s properties.

  2. Use the Guidelines section of the Inspector to edit the guideline’s attributes, including its color.
