I may be experiencing the same lineweight issue. In the dimstyle manager box I choose the L.W.s ( and I notice a dashed line showing up just fine, but then they never print out. I'm taking classes in CAD. Everytime I've started a drawing in class (on the class computer, CAD 2005)) I've been okay, but if the drawing starts at home on my computer, (CADLT '06) then the lineweights don't print, even when file is moved to class. Also, my dim text, (but not the normal text - even though the same style employed on the mark) shows up way too big on the screen if the drawing started at home - settings checked and double checked every setting same as class, seems like a faulty software issue, any ideas???
