To jump to a new frame you can use gotoAndStop(...) or gotoAndPlay(...), where "..." represents a frame numnber or label, and if they happen to be adjacent frames you can use nextFrame() or prevFrame() (which act like gotoAndStop() commands).
If you happen to be trying to tell something other than the current timeline to go to a new frame, then you need to target the intended object/timeline.
This can tell the timeline that holds the object that contains this line to move to a new frame...
This tells an object on the same timeline to move to a new frame...
If you are after something more complex than that then I have probably missed the point of your posting... I don't see where 3D fits into the discussion of moving to frames.
