I am using Inventor Professional 2012 and I have created complex iparts and iassemblies and I am not able to change the BOM structure of the parts simply because they are intelligent. I require the tables and features that the iparts and iassemblies can create but they are coming up read only and can not modify the BOM information. Is there a way to change the read only aspect of an ipart or iassembly?
As far as I know, you can't change it.
You will have to modify the iPart table and then re-generate the part.
