Hi Ricardo,
>>>>>>I would like to just see my DWG files in the finder. any ideas?
I'm afraid, it is not possible as it is macOS dependent feature.
AutoCAD uses standard "Open document" window, but on macOS it shows all files.
DWG files are active in that window - you can select them to open in application, at the same time all other files are grayed-out - you cannot select them.
