Q) Do I have to work with the FLX files in MSCAD (or Express) or can I work with DWG files directly?

A) MSCAD 2002 has the ability to work with DWG files as it’s native format. This means, if you choose to, you no longer have to work with FLX files, in favour of the DWG format. You can set this by running the CONFIG command and setting the File Formats on the dialog, as desired.
