DWG Version Converter

If you need to open a newer version of software because you are using an older version of AutoCAD you can use DWG TrueView™ available as a free download from Autodesk (there is even a 64 bit version available). It is also handy to send it to clients or other engineers instead of doing all of the work in converting the files to an older version.

For Civil 3D files you will need to make sure Proxygraphics is set to 1 before sending out for them to see something other than empty rectangles. Also the labels don't rotate to match the paperspace viewport, only rotate per Model Space.
