Fastest way to combine paths?

[Jon G]

Hi,

I received a logo from our sponsor, one that was made with some AutoCAD program (!!!). My contact person has converted this .dwg file to pdf with some freeware application, and the pdf opens just fine in Xara... with one problem:

All the paths that form the logotype are separate lines :-( what would be that easiest way to combine them, so I could fill the shapes? The imported pdf is attached.

thanks for any advice,

.jon
