I'm getting some metal cut-outs done of a design I did up in Photoshop and converted in Illustrator, but the end product is not that nice because Mr Metalworker has said "the Drawing file is in Polylines (many lines to make up one) because of this the laser takes them as individual contours and cuts it at less than half speed."
He goes on to say that I need to "convert it into ‘lines and arcs’ and not ‘polylines’ then I think we can get to the point where no cleaning, filing or deburring needs to take place."
How do I do this? I'm a bit naive when it comes to this sort of thing and googling has led me to believe I need to do it in a CAD program?
