You can open AutoCAD drawings in Visio. We recommend this if you want to quickly open an AutoCAD file without concern for drawing scale.
AutoCAD versions supported
If you are a subscriber of Visio Plan 2, you can open a .dwg or .dxf file from AutoCAD versions 2007 through 2017. If you are not a subscriber, make sure to save the file as an AutoCAD 2007 .dwg or .dxf file before opening it.
Working at the same scale as AutoCAD
