Polyline around a hatch?

I got a dwg file from an file created in adobe illustrator and the line work is fragmented (curves for example). I dont want to spend hours redrawing it. It does have a solid hatch. Am I able to have rhino generate clean polylines around the hatch elements?

May have just answered my own question … found the _fitcrv command and it does the trick. :nerd_face:

Hi Peter - use DupBorder of this.
