Depends a bit on what a 'fixed end point' is to you. You can set the end
point of a motion path easily.
- Apply a motion path
- Click off and then click on just the red arrow (the end point of the
motion path)
- Click and drag red arrow to any desired position
**Note: Motion Paths are figured on the center of the object (eg. the red
arrow is the stopping point for the dead center of the object).
