I'm currently making the transition from AutoCAD 14 to Architectural Desktop 3.3 and I'm experiencing a problem with printing. When I send a drawing to print as a plot file to a DesignJet HP750c I click on "LINES MERGE", but when I look at the plot file using Repro desk it shows that that feature has been disregarded. The plot files will pick what ever it reads as above and hide what it believes to be underneath instead of merging the lines. Does anybody know what could be causing this? By the way I'm using the latest driver from HP.
