pen settings/different lineweights

I want to set my settings up to have different lineweights for each color I use. I have set up a new CTB (plot style table). From there I edited things from the Plot Style Table Editor. I changed the colors and linetypes. For example I wanted the Color Blue to have a width of .003 and Red to have a width of .007. When I do a plot preview the linetypes aren't correct. They show up really fat..like they have a width. I have my scale lineweights on. Any idea on what I need to do? Any help would be great. Thanks

 

Turn scale lineweights off.... this multiplies the lineweight by the plot
scale factor and can be messed up if your plotting in mm but your drawing is
in inches or vice versa.
