Inventor 2020.5 - Frame Generator Part Number from custom Content Center family table

[p.kaliszczyk]

Hi everyone!

Inventor version: 2020.5

I have created custom structural shapes intented to be used in the Content Center library and accesed through the frame generator. I want them to behave in the same as regular structural shapes, preinstalled with Inventor.

Everything works well, except getting Part Number from Content Center family tree while generating parts by using frame generator - even that I have the tickbox checked "on":

I'm getting custom part numbers, like this:

The expression for this family Part Number looks like this:

and it should look like this:

Am I missing something? I have tried almost everything, without any success yet; also been browsing the forum for a couple of hours and couldn't find anything related to this problem.

I think Inventor is just grabbing the file naming scheme for frame generator. I'm not sure you can change that to your liking, but you could try reconstructing the custom content center family naming structure here:
Tools > App. Options > File Naming Defaults.

But it seems to work just fine for predefined structural shapes:

This is my goal, I want to achieve the same result for custom structural shapes. 

I checked family tables from pre-installed structural shapes and tried to name all variables of my custom structural shape the same, but it still doesn't work.

I'm like 100% sure that there is a way for frame generator to set part numbers of freshly generated parts according to rule specified in the Content Center family table, otherwise why would be there a tickbox to turn the feature on and off? 🙂
