Default Joining a large quantity of vectors

Got a job that involves me cutting about 300 parts out of aluminum. the customer provided dxfs, but when I bring them into V-carve they are not joined. They have everything nested into a 4'x8' sheet, but I'm going to be cutting the parts on 2'x4' sheets. Is there any way for me to quickly join a group of lines together? I need to join the outside profile of the parts and then take the outside profile and all the inside vectors and group them all together to get them to nest correctly. Is there any way to do this faster than select line, join, next line, join, next line, join... ad nauseum.. Anyone have a faster method or am I on the slow boat to china? Maybe If I were to bring them in differently instead of opening the dxfs?

Pete...
Work with your customer to get a better export. I am attaching a short doc from Gerry Gradzinski that explains the process. Forward this to the customer and see if they can resubmit the export. If they don't wish to, tell them that there is an hourly charge to clean up their files. Or eat it.

Thanks Gary. I have access to autocad at my day job, so maybe I'll open all the dxfs and save them all as version 12. I think I know what happened with this file. Someone already nested the parts in OMAX waterjet software and saved the files as 1997 autocad dxfs.

Good deal Pete... Let us know how it turns out and what it took to get them exploded. There is one more method that uses a free CAD program called Draftsight. Open all DXF's in Draftsight, select "Explode" and resave.

Just saving them as v12 probably won't make any difference.
You'll most likely need to use the PEDIT command in AutoCAD to convert them into polylines and join and close them.

From my experience, most AutoCAD users don't use polylines, which results in drawings with individual, un-joined lines and arcs. Not ideal for CNC use.

Whenever you're working with someone else's drawings, it's a good idea to see what you have to work with before pricing a job, so you know before hand if they'll require extensive editing.

Hey Pete,

I'll take a look if you want to email me the file. I run into this a good bit and use my Corel software to fix it.

Its getting re-worked by the customer. If corel can fix this quickly, maybe I'll drop the hammer and pick it up, because I do a lot of image importing and tracing.
