Motion Path question
 

How can i add to my motion path another curve to enlarge it ?
i tryied to do that and the history of the motion was kept, but the motion path dissapeared from the channel box.

is there another way to do that ?

i have a ready motion at a motion path and i just want to grow up this path witout change the motion that is already done.

You should just be able to assign your object to follow another path, and set the keyframes on the second path the start when the first path ends.
