Convert a shape to a path
In the Tools panel, click Selection , and then select the shape you want to convert into a path.
On the Object menu, point to Path, and then click Convert to Path.
You will not be able to edit properties that are specific to a shape (such as the corner radius of a rectangle) after converting the shape to a path. Also, if a style was applied to the shape before conversion, the properties of the converted path will be reset to the defaults for a path (no fill brush, and a black stroke).
