There's another trick that I recently came across:

"Include in Schedules". It seems to be possible to tell ANY geometric component (not the annotations, detail components, and stuff) show up in the schedules AT ALL... regardless of visibility. Was this always there??? Never noticed it before. It's a yes/no parameter which you can even link through

Are you saying that if I import a family with nested families in it and I import into a project, I can make an assembly with a parts list and it will show up?
if so please explain.

using Genric families shared

RST 2012

Thank you

If you mean by "an assembly with a parts list" a schedule of nested shared family instances within a host family, or assembly, then sure.

If you're using generic families you want to schedule them out with a Multi-Category Schedule, which you may need to filter by family, or type, depending on what elements you want to show (plate, bolt, nut, etc) then you've the option to sort the schedule by instances or by type or any other parameter of your choice.

This will "catch all" in that every instance of a generic model within your project will be counted - so if you've more than one of these assemblies you're going to have double, triple whatever the multiplication, of those nested families.

Tieing them together could be tricky, I can only imagine you might use a clever numbering system for their "Mark". Or a text shared parameter to assign a similar "Mark" to them.

Update information

I have attached a small simple project using reviit structure 2012.
It has the new assembly in it.
I cannot have the schedule in the assembly to pick up nested families..

Thanks for your help in advance.

Ehmm, I'm guessing that you are looking at the wrong kind of schedule here. The assembly schedule doesn't pick it up, but it's not meant to. It's meant to schedule Assemblies, not the parts.
The Multi-Category Schedule is picking up both the Panel_test and Plate_test components.

That is what is thought.

Thanks,
