Make and Edit choose the Intertwine tool: hovering highlights the overlap
area under the pointer, a click swaps which object is on top there, and a
path drawn around overlaps (Shift: a rectangle) arranges every overlap
inside it; Esc or Enter goes back to the tool chosen before. The overlap
faces move to vectorcraft-tools, shared by the tool and the command.
Clicks inside a raised area pick the member drawn on top there, the
Object menu gets the Intertwine submenu, and the new labels and the
predicate message are translated in the complete catalogs. docs/gaps.md
records what landed under G13.
An Intertwine group keeps its objects as they are, in their own stacking
order; each member can be drawn over the others in an area of its own.
The group draws, hits, saves and exports through its live expansion, so the
members stay editable and Release gives them back unchanged.
object.intertwine.arrange picks an overlap area by a click point or by a
closed path drawn around overlaps and toggles which member is on top
there, or brings a member to the front or sends it to the back where three
or more objects overlap.
