I'm having issues with converting *.cdr* drawing (architectural layouts & elevations) files to .dwg or .dxf.

I'm not sure if these drawings were originally made with AutoCAD but when I attempted a Save-as using the .dwg, I got one AutoCAD picture and nine .jpg files. By AutoCAD picture, I mean a picture pasted in AutoCAD and edited with Paint. On the other hand, when I saved as .dxf, nothing was saved.

Does this mean that I cannot successfully convert these to drawings to AutoCAD? That would mean that I won't be able to modify it cos I didn't even bother trying in CorelDraw, as I hate doing layout drawings with that software... or any other for that matter. Well, except... ofcourse now, Revit.

Any help? Anyone?
