The last shot in a traverse is always open ended (infinite). Entering a horizontal distance here sets the offset from the previous shot for this last shot.

NOTE: Features will be given the name of the traverse. If side shots are included (see above), they will automatically be given the same Alphanumeric ID and a unique Numeric ID. For instance if the name is TRAV then the centerline will be TRAV-0 and sideshots will be TRAV-1, TRAV-2 and so on.
