Problem importing data from DWGeditor to solidworks

Good morning,

I have a very large AutoCAD drawing that is split over threesheets. the information I need to get at and bring into solidworksis found on sheet 1, which is the model tab.
Selecting the elements I require, ctrl+c and ctrl+v does not workbecause it does not pick up all the elements, instead I get astrange mish mash of bits which is in effect useless. I am awarethat this is most probably down to the layers used in the creationof the drawing but when trying to import the drawing via opening itin Solidworks as a .dxf the same thing happens. I select only thelayer I require and nothing comes out???

Does anybody have any ideas why a line can be shown in DWGeditorbut it is not considered worthy enough to be placed intoSolidworks?

So my question is in short, how can I get the dwg into Solidworkswithout hitting my head on the desk.

Many thanks for reading this email, all ideas good or bad will berecieved with gratitude.
