Sending us drawing files.
The best thing to do if you don't use an early version
of ACAD is plot the file to disk as a bit map gif. ACAD R12 does this well
but I can't tell you what other CAD programs do.

Some will output the file as a bmp, jpg, gif, tiff, etc., etc.,
bit maps. That is good too.

Since DXFs in general don't work across CAD programs.
Even CAD programs made by the same company. Generally they
are useless.

Next best thing is a screen capture program.
Capture the CAD display while in the CAD program. 
Plenty of free screen capture program ones on the internet.
