I've copied the contents of a Gerber GM1 file in Altium 18 to Autocad Lt in the past. I no longer remember how I accomplished this simple task. Is there an easy way to transfer a mechanical layer to a dxf file?
I was able to solve my issue: Starting Altium directly on the Gerber file doesn't offer an DXF export. I was able to start Altium/PCB, then import the Gerber file and then export DXF.
