missing component with custom catalog

Hello group,

I'm trying to create a new IFX catalog, so I will ask several questions this days 🙂

at the first time, please let me wish you an happy new year guys.

and here is my first question:

I could add a custom screw, and it works with issues (this is for a next topic). when I save my assembly, close the CREO session (I use CREO4), and re open the assembly in a new CREO session, my screw is missing.

I try several things in the IFX_CATALOGS, like

1)

#screws
vis_rabourdin

2)

#screws
vis_rabourdin

1021_5_08<vis_rabourdin>
1021_5_10<vis_rabourdin>
1021_5_12<vis_rabourdin>
1021_5_14<vis_rabourdin>

or

3)

#screws
vis_rabourdin

1021_5_08
1021_5_10
1021_5_12
1021_5_14

without success.

please note that is a family table I use.

does someone can help me to understand why the component cannot be retrieve alone?

thanks in advance,

Ron
