Inventor Nesting fails to import iParts (Internal COM Error)

[A3XXFR]

Hello,

I have been trying to get inventor nesting to import an assemble for the better part of the past 5 or so hours. Initially when I tried to import the assembly, the utility would think for about 5-10min then spit out nothing. The nesting tab wouldn't show any geometry sources. No errors or warnings. Nothing. I tried many things like deleting bolts and anything that wasn't sheet metal to try and get it to work. 

Eventually I went back to an old nesting file I had made with an earlier version the assembly. Here when I tried to refresh the nest the program actually gave an error: Reload Error: Internal COM Error. I little more digging and it seems this error is only on iParts (The table that generates files). I have also tried importing the iPart directly into a new nesting file and the issue persists. Is this a limitation of the software? Can we not use iParts? If not how can the issue be resolved?

I have attached a screenshot of the message and one example of the offending files (Master file and generated Files). Using Inventor 2021 + Nesting Utility 2021.

Thank you for your help in advance.

It's a late reply, but I'm up against the same issue.

iPart factory contains (8) members, and I'd just like to use these to do nest layouts - 

(48) of iPartmember1

(36) of iPartmember2

(24) of iPartmember3

etc.

I did see another (older) thread that suggested maybe adding a key to the factory. I did that and still get the Internal COM error. No import.

Any thoughts appreciated!

The part file needs to have a Flat Pattern created to be able to nest it.
