We work on AutoCAD2002 & Windows2000 professional. Every time I plot this drawing to HP800 or PDF995, I get this fatal error -"Unhandled Access Violation reading 0xXXX Exception @ 4bfd9bh." The drawing file is like this. We have plant layout drawing that contains many 3D models (Plant structure– 5 stories and processing machines) that are x-ref into this drawing. We x-ref this plant layout into template drawing that has title block, etc set up. Then x-clip this plant layout in order to get plan view of a single floor. We also use mview-hide option in order to eliminate clutter. When I plot this drawing, it gets fatal error that I mentioned earlier. The exception number is always same. We were able to plot this drawing last week. The change is we add some moreobject in that plant layout. Does anyone know where I should look into to solve this problem? Our dead line is just in few days. Please help
