.idx File Structure

[Dale_Rosema]

What is the structure of the .idx file that is created from family tables. From what I can understand the second column is the instance and the 3rd column is the generic, but what is the first column. In my file, I have 1's and 2's. Is it some sort of hierarchy?

We can call it as data identifier ..... 1 for assemblies and 2 for parts in index file.

When I got an error recently, it also had a "0". Was this truely an error or is there something for zero?

I think that was an error, possibly updating index may correct such information. If you have any data/sample please share.

It did. I just wanted to make sure I wasn't overlooking something.
