External Reference Manager
Edit
Reference Geometry (Sketch
Level)

The External
Reference Manager is used to replay, edit or delete external reference
that you have added to the active sketch.
An example of an external reference is when you use the Project a Reference Point command to project a point from the active part (or another component) onto the active sketch plane.
The options available from the External Reference Manager are similar to those of the History Manager.
Pick
repeatedly from the Replay External References Manager to replay each
external reference or pick
to replay all references.
As each external reference is regenerated, it is removed from the replay
list. If each external reference replays successfully, the following message
is displayed.
Refer to the History Manager for more information about the function of each icon.
