I had recently completed an extremely complicated .ipt of a die-cast part.
Normally I hit "rebuild all" frequently during modeling, but I was under a
deadline and just forged ahead even though the part was starting to behave
rather flakily. Big mistake. A few weeks later when trying to make a few
simple sketch edits, I noticed that referenced edges kept losing their
references. I hit rebuild all, waited about 10 minutes and about 90% of the
features in the tree lit up with yellow exclamations. It seems that a flat
plate feature at the beginning of the part lost it's definition. I had no
warning of this till I hit "rebuild all". If I'd have been using it
regularly I may have saved myself the chore of manually repairing each
damaged feature. Inventor doesn't seem to be very fond of complex parts.
"Rebuild all" is the only thing that keeps it sane.

ps I'm still using 5.3 so it wasn't a migration issue.
