Description:

      The Paste command (Edit > Paste) is used in conjunction with the Copy command.  If you use the Copy (Edit > Copy) command to copy selected shapes, faces, edges, or vertices to the clipboard, the Paste command will create a new shape that has the same structure as that which you copied to the clipboard.

Notes:

-You can use the Paste command repeatedly to paste as many duplicates as you want of whatever may be on the clipboard.

-Also see the Copy command help file.
