Trim Open Paths

The Trim Open Paths operation is used to trim off one or multiple selected open paths where they are intersected by other visible, unlocked paths (or by self-intersections). By default, the trimming can occur from either end of the path (the shorter end, if the path is intersected only once; otherwise both ends), but Shift can be held while clicking the button to force trimming from only one end; which end depends on the preferences setting.

Clicking the icon to the right of the button will bring up the Trim Open Paths Preferences dialog:

QuickOps Trim Open Paths Preferences

1. Shift-Clicking Button Trims Path

Specifies which side of the path to trim if the button is clicked with Shift held down.

2. Split Variable Width Stroke Profiles

When enabled, and the trimmed path has a variable width stroke, the stroke profile will be split to keep the width of the untrimmed section as close to the original as possible.
