Just recently upgraded to 2006 and all plots are plotting portrait. I have tried to everything I know, including selecting portrait under custom properties and saving it as a new .pc3 file. I have even created a custom sheet (36X24) and it still plots portrait. The other computers (running 2006 also) show "ARCH 24X36 (landscape)" and/or" (portrait)", but my system only shows "ARCH 24X36". Have an HP 750C and windows XP. Any help would be greatly appreciated.
