How do i get my broken lines in a drawing(model space) to plot as they look in drawing when using paper space where they show up as solid lines. As far as i can see setting the line on different layers in model space  doesn't help  when plotting. i am sure but cant for the life of me remember the "trick "  to plotting a broken line.

It all has to do with the settings for MSLTSCALE, PSLTSCALE and LTSCALE.  Try these settings:MSLTSCALE = 1
LTSCALE = 0.5 (some users insist on a setting of 1)
PSLTSCALE = 1
