Re-routing to Ignore Clips
You can update a route to ignore clips.
To unhook a route segment from a clip or hanger:
Click Unhook
From Clip 
(Routing Tools toolbar) or Routing,
Routing Tools, Unhook
From Clip.
Specify route segments in the Unhook
From Clip PropertyManager.
Click 
.
You can also right-click the sketch segment
under the clip and select Unhook from
clip.
If you delete a clip from the route sub-assembly, then the next time
you edit the route, the software informs you that a clip has been deleted
and asks if you want to update the route. If you re-route, the route updates
to a more direct path ignoring the original clip.
