Our office has just upgraded to AutoCAD LT 2013 and are having a boat-load of problems. One major one is that none of our assigned linetypes will plot correctly. For instance, when I'm drawing a building section at 1:1 in model space it shows our hidden lines correctly displayed as a dashed linetype, but when I create a new layout for a half-size print (11x17) and set the drawing to be scaled at 1/4"=1'-0" when I click on the layout tab to plot the drawing the lines look solid and end up printing solid as well. When I type in the LTSCALE command it says that it's properly scaled at .2500 inches (1/4") and PSLTSALE command set at 1. So, I can't figure out why the linetypes won't print correctly. It could possibly be our assigned printer settings or an issue with our .CTB standards, but I can't seem to find anything wrong with those.
