Sorry about the thread hijack, but I have a modular iPart of 35-pitch roller chain for Inventor that uses an embedded Excel spreadsheet to create an assembly of roller chain. I cannot claim credit for creating this part, as I found it on the hard drive of one of Team 228's 3DS Max/Inventor computers three years ago, but it's certainly one of the most useful parts I've ever had in Inventor!

As far as backwards compatibility goes, I know for sure it works in Inventor 7.
