Whenever Export-DXF is run, it writes a log file. The log file has the same name as the dxf file, but with a .log extension rather than .dxf. If a message or warning is printed by MODEL, or if the DXF files does not contain what the user expects, further details are often available in the log file. The log file is plain text, and may be viewed with any text editor such as Notepad.
