Interf ace
Since this is a world-space rather than an
object-space modifier, the object is affected in
worldspacecoordinates,andalsoaffectedbythe
relative position of the path to the object. Thus, if
you transform the object relative to the path, or
vice-versa, it has an affect on the deformation.
Generally speaking, the Path Deform world-space
modifier leaves the path in place while moving
the object to the path, while the Path D eform
object-space modifier leaves the object in place
while moving the path to the object.
For all parameters except the following, refer to
the
PathDeform modifier (page 1–748) .
Path Deform group
Move to Path—Moves the object from its original
position to the start of the path.
