Try AutoCAD TrueView. It has a measurement tool which is less than intuitive. The review tools don't show up dimensioning data as you need to manually add that to the drawing and it isn't natively part of the drawing format (stupid I know).
Thank you Adrian! I've downloaded a free .dxf viewer (SolidWorks eDrawings), but I can't see measurements or dimensionality on the drawing, just what you see on the attached screen shot.
Is there a better program I should try to be able to see the rest of the drawing?
