I received an Autocad file from another person, opened it with Autocad 2011 LT, and it looks fine. But when I go to print preview all the lines are very thick, making the detail of the drawing difficult to see. I've tried manually changing the lineweights but it has no effect on some of the layers. Is there an easier way to fix this other than recreating layers?
