Sorry Groundhog, when you posted "... I want to be able to make 2D parametric drawings and save them in a format that I can open in VisualMIll 2012" I thought Fusion was creating a parametric/linked drawing file. My misunderstanding.
Doing some digging it looks like the .dwg files created by Fusion won't be easily converted to the basic drawing format. From a post in the Autodesk forums: "The 2D drawings created in Fusion 360 contain drawing view objects, similar to those created by the Model Documentation feature in AutoCAD. These do not support copy/paste or CHSPACE."
Those "view objects" are the linework of the drawing which only show up in Paperspace as a kind of Block, and you'd need them in Modelspace as lines, arcs, circles, etc.. It appears you would need a copy of AutoCAD to convert the view objects into linework usable in your CNC software.
