I have an upcoming show where there is a tracking stage element needed, but is only present in act 3, and the rigging system needs to be put in place during a quick change.
Space and time restrictions mean that I cannot get a winch in RORO configuration in the space, so I am planning on using two overhead lifting axes for the effect and diverting them across the floor.
Cueing sequence would be to bring in the points during the change, connect them to the tracking SWR, tension them and then control them from with a group, with one of the axes having a position scale offset as -100%. Ideally I would like the ability to lock this group automatically once the system is in tension to avoid an operator from being able to drive the individual axes. (I have ruled myself into a safe situation with a sim IO and a custom position error function to disable motion if they are out of position to each other, however stopping this from being able to happen in the first place would be even better as an additional control measure.)
Ideally locking a group could be done by both a command that you could create a cue line for, but at the very least a rule action to trigger this change would be ideal. If doing this on the group is too challenging, it would be sufficient to be able to select a group to lock to on the axis, as part of an additional rule action.
