Don't think so. In DCAD, there are two ways to use line weight. One, is the "old school" method that I have always used and that is making certain lines on the screen into heavier weight lines. That technique does not translate to other CADprograms as far as I know. The other technique works the same with AwfulCAD and other CAD programs and that is to designate line weights by use of the Pen Table. You can set different pen colors to print out at different line weights. Those would translate to other CAD programs if in those programs, their pen tables for different line colors matched up to the line weights in your pen tables.
