Group Spacing

A RoboFont extension to enable group spacing in the Space Center.

Supports importing and exporting spacing groups to .groupSpacing files.

How to use the tool

1. Define groups

Create left/right kerning groups using the Groups Editor.

2. Visualize siblings

Select a glyph in the Space Center and see all other glyphs in the same left/right spacing group.

3. Copy margins

Transfer the left/right margin of the current glyph to all other glyphs in the group.

Optionally, measure margins using the beam.
