Plotter Files

Hi everyone, I receive artwork which I modify to suit what I need. In doing this I add lines and then save as a .PLT file. I then send this to my engraver but, the engraver sees all of the edited lines as a separate entity and therefore cuts them first and then goes back and does the original lines that were not edited.

Is there a way of making them all one continuous cutting path as it takes double the time to cut with the engraver jumping from one part of the job to another.

Thanks

Steve
