This is normal, the crs is not save in dxf.  Is the crs in longitude and latitude (degrees) or in meters? If it is in long lat, that may cause additional problems.  Reproject and save it in QGIS in a local utm zone in meter and see what happens in the cad.

What CAD are you using? Try DraftSight.  It is free in 2D but not OpenSource. Did you find a zoom to layer function in the CAD. It is very hard to find the lines manually.

>>>> AutoCAD programs have a tendency to open the file either zoomed out or zoomed away from our zone of interest.  Ex.  Your lines are in Canada but the files open in France.  You need to find your data. Zoom in, zoom out or pan until you find it.  Sometimes, you have a function saying « zoom to layer extent ».  If that does not work, try to find your data looking at coordinates system.
