The new Trim at Crossings Tool removes stretches of paths between the
places where they are crossed by another path or by themselves. A click
removes the stretch under the pointer, a drag removes every stretch its
rectangle touches, and an Alt-drag removes every stretch its freehand
line crosses. It works on every path that can be edited, selected or
not, and each gesture is one undo step.
- `addon.pathtools.trim {at, tolerance?}`, `{rect}` or `{points}` is the
command behind the tool. A closed path that loses a stretch becomes
open, an open path that loses a middle stretch becomes two paths with
its appearance in its place in the stacking order, and a path that
nothing crosses is removed whole. The stretches that stay get no new
anchors.
- Hidden and locked paths, guides and clipping paths are not trimmed and
do not count as crossing. Only the paths the gesture reaches are
searched for crossings, and one work limit covers every path the
command trims.
- `crossings_on` and `crossings_on_within` in `vectorcraft-pathops` find
the crossings on one path and compare it only with the segments in
its box.
- The new tool shares the crossing search with Add Points at Crossings
and Split at Crossings, so those change too: two segments of a path
that meet at an anchor, directly or across segments with no length,
now count as crossing where they cross again away from that anchor,
and do not count as crossing at the anchor itself. With Self
Crossings, a curved segment that loops over itself counts as crossing
itself. Before, both crossings were missed.
- The tool is an add-on tool: Object › Plug-ins › Path Precision Tools
and the All Tools drawer list it, it has no shortcut, and neither
shipped toolbar shows it.
