Equal was applied through a generic gather-then-apply flow and, with the default size-retaining solve mode, never changed anything: the solver held both sizes and the relation could not be met. Now: - GCEQUAL joins ECONSTRAINT and GEOMCONSTRAINT Equal; both objects are picked inside the command (`Select first object or [Multiple]:`, `Select second object:`; Multiple gathers `Select objects to make equal to the first:`), a selection made beforehand is not used, a miss says `No object found.` and re-asks, an unsupported object or the same object twice is reported and re-asked, a repeat is refused. - The follower is resized in place before the relation is added: a line or straight polyline segment keeps its start and direction and its end moves to the first object's length; a circle or arc keeps its center and takes the radius. - During edits the side that is not being edited follows the same rule: its size is not retained, its start (or center) and other vertices are held and its direction kept, so only its length or radius changes; a chain of Equal relations follows along.
