There aren't a lot of "free" converters for converting between autoCAD DXF or DWG file format and Visio drawings, because Visio already reads in AutoCAD files and does the conversion. This makes my situation of wanting to do this without having a copy of Visio sort of funny.
You can almost hear Microsoft sighing in this article as they explain how to open menus and click on options: https://support.office.com/en-us/article/Open-insert-convert-and-save-DWG-and-DXF-AutoCAD-drawings-60cab691-0f4c-4fc9-b775-583273c8dac5

Supposedly TrueView can do a conversion to Visio, but after so many hints to just use Visio, I gave up and sent my AutoCAD drawing to a coworker who has Visio instead: https://www.visiozone.com/?p=26
