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. With Creo 7.0.1.0, you can control the snapping behavior for normal and tangent placement of leader annotations.
In the part and drawing mode, Annotate > Annotations > Snap To Guides.
In the drawing mode, click Table > Balloons > Snap To Guides.
Use the config option “annotation_snap_to_guide_range” to control snapping sensitivity and behavior
