FYI & Beware!! I have allot of molds & multi-sheet mold drawings that were designed in SWX 2004 and before. I upgraded to 2005 sp0.1 and now I am only able to open about 1 in 5 of the mold drawings. Error: Solidworks encountered a problem opening document BLA BLA BLA. Bang: CTD. I sent one of them to the VAR and they confirmed the problem in 2005, opened fine in 2004. They have forwarded to SWX. I don't know if it is a BOM problem or what. Assemblies and parts open fine with the exception of some seemingly permanent rebuild symbols in assemblies. Good Luck Mike Eckstein
