Starting with Creo 7, when you place a leader annotation on an edge, the normal or tangent leaders appear as soon as the cursor position is beyond the snapping angle threshold. You may turn off this snapping in order to place a leader annotation very close to a normal or a tangent placement without the snapping.
You can now control the snapping behavior and also decide on the snapping sensitivity using a configuration option annotation_snap_to_guide_range.
User Interface: In a part or in a drawing, click Annotate > Annotations > Snap To Guides
