Adding bodies to sketch

I’ve got 8 bodies (letters and stars) in my work space I derived from another project and I don’t know how to add them to a sketch so I can export them as a DFX for Sheetcam. Is there a way to add all of them as is to a new sketch? Or create a sketch in the work space they’d attach to? Thanks in advance.

if you already have a sketch done you need to right click on sketch on the cam tree and you show be able to place your new bodies at that time.
