QuickCAD

I have somebody sending me plans from quickCAD, which creates .cad files. When he converts them to a .dwg file to send to us for opening in Chief, it is ignoring the line weights, and importing all lines with one width and ruining the integrity of the drawing. Does anybody have any suggestions or fixes for this? Thanks in advance.

Hi John, I have QuickCad Release 7 which is produced from AutoDesk. I haven't used it ever since I started using CA. I might try to do something with it this weekend and save it as a dwg and see what happens. I used it mainly to draw cabinet details.
