The Create/Edit Trajectory dialog box appears.
A context toolbar also appears that provides Reconnect.

Reconnect in the context toolbar is always available for each manufacturing weld regardless if the fastener is connected or not. This allows you to connect a manufacturing weld to a different fastener implemented by the parent operation of the Spot weld trajectory being edited.
Reconnect
provided in the Create/Edit Trajectory dialog box is useful for reconnecting the manufacturing welds that are disconnected from the fasteners, as well as move tags from other trajectories to the spot weld trajectory currently being edited or created.
