Apple Motion 4 - Manual (Page 831)

To use geometry for a text path source
1 Import (or draw) the shape you want to use as the path source.
2 Select the text on a path, then choose Geometry from the Path Shape pop-up menu.
The Shape Source well appears in the Inspector.
3 From the Layers tab, drag the shape to the Shape Source well.
4 When the pointer becomes a curved arrow, release the mouse button.
A thumbnail of the shape appears in the well and the shape is used as the source shape
for the text path.
Note: You may want to disable the source shape in the Layers tab so it is not visible in
your project.
