I found something that makes the process of exporting a face to a DXF file a bit easier because you can select the face of a body and export directly to DXF.
It is an Add-in called “DXF4Laser” and after installing and testing, it seems to work so far.
From Fusion 360, select “Fusion 360 App Store” from the Add-ins menu. (or go here: [https://apps.autodesk.com/en])
Type “DXF4Laser” in the search box.
Download and install the add-in. (be sure to start it)
EDIT:
There’s also an Autodesk DXF Post file available too, but I have to figure out how to use the CAM module in Fusion 360 first…
Search for DXF here

It appears there might be another post file someone wrote to export DXF too… with a little documentation.
