I am work on Draftsight 2D software. When I set up a print page or PDF, the program does not detect the drawing. it does however pick up the adjustable box on the sheet layouts. I have selected monochrome and various other plots,it does not fix the problem. It is not a problem on the printing options list, I have tried all of those options.  perhaps it is a layer problem?  why is it not showing the drawing?  It's urgent. please help.
