Copy 
Edit > Copy (Ctrl+C)
 

Description:

      The Copy command (Edit > Copy) will copy whatever shapes, faces, edges, or vertices you have currently selected to the clipboard.  You can then use the Paste command to create a new shape that has the same structure as that which you copied to the clipboard.  You could, for example, copy a sequence of edges from one shape, paste them to make a new shape, then use that new shape as a path for a Path Extrusion Object to make an extrusion that exactly follows the contours of the original shape.
