Use the Follow Me tool to duplicate the profile of a face along a path. This tool is especially useful when trying to add details to a model, such as a crown molding, because you can draw the profile of the molding at one end of a path on the model and using the Follow Me tool continue that detail along the path. You can manually and automatically extrude a face along a path using the Follow Me tool. Activate the Follow Me tool from the Tools menu, the Modification Toolbar (Microsoft Windows), or the tool Palette (Mac OS X).
