How to create a path through a drawing for index cutting on a plasma cutter in Inkscape

This video explains how I make files in order to index cut on a plasma table in Inkscape. This is the first step in the process follow the second video on how to create cut files in Sheetcam for index cutting. I apologize that you can't see my drop down windows I don't have very good software.

Everytime I try this I get an error stating "cannot perform operation, one of the objects isn't a path", or something to that degree. Do I have to turn my imported drawing into a path first? I've spent way to many hours trying to get it to cut in half!

Yes everything needs to be a path. Sometimes you have to check and make sure your object is ungrouped. As a good practice I always ungroup an object twice before converting it to a path. I think sometimes there is a glitch in the program and it doesn't always take. Sorry it took so long to get back.
