Duplicate curves on DXF/DWG import

Rhino Rhino for Windows
1

I imported a DXF file into Rhino and get a block. I then Explode the block and all the curves are duplicate. Tried DWG import and the same thing. The file is exported from Illustrator to create a file to laser engrave with other elements from Rhino. Normally I’d just go over every curve and delete the dups but there are a few thousand little curves and they are EXACT dups right on top of each other. I tried SELDUP but that didn’t find one duplicate…
I’m running Rhino 5 and even downloaded V6 trial to see if it would make a difference. I think Grasshopper/Kangaroo could do the trick but I have no idea how to use it.
The question is, Is there any way to import the file and not get duplicates? or is there something I’m missing? Its a pretty complex design of a tree that I will hatch to engrave and then incorporate into some other curves that the laser will cut.

Thanks so much guys for any help.

Can you provide more detail about what you are trying to accomplish? I see nothing unusual about the imported file. When importing dynamic Autocad blocks its going to bring in all versions, that would need to be corrected in Autocad.(Burst command perhaps)
