Some vector drawings (like the .draw files from Acorn) can be translated and converted to a 2D DWG CAD drawing.
The catch with draw to dwg conversion would be to find a program capable doing so, which can not always be easy, especially in case of older graphics formats. CorelDRAW supposedly still supports formats from Acorn, and it also can save vectors as DWG drawings, so it would make ideal choice for this conversion. You can download a trial version and try it yourself.
