The Paste command is used in conjunction with the Copy command. If you use the 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.
- 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.
