I have several wall fixture host families that use the same wall standards, and a smattering of clips and attachements that i have created as separate nested families.  For instance, a wall standard nested family is the same family that is used in 3 different hosted families.  What I want to do is create a schedule that shows the hosted families with their respective nested components so that I can easily show that host family 'A' contains 2 wall standards, etc, and host family 'B' contains 4 wall standards, etc. 

This seems like a simple sorting problem until you go to do it.  I can create a schedule showing the total number of wall standards in the project, but I'm struggling to sort them by their respective host families in an automated way.

My current workaround is a project paramater that references the family type for the host family.  My nested families are Generic Opjects, and my host families are Furniture System families.  The project parameter is called "HOST FAMILY" which is applied to all generic objects, and references Furniture Systems families.  The unfortunate thing about this setup is that it forces me to have it as an instance parameter, which requires me to adjust each nested object to reference its corresponding host family. If i set as a type parameter, it forces all of the nested families to reference the same host object.

There has to be a way to automate this so that the nested families can be sorted by their host family....and I'm missing it!

I have a solution to my problem:  I created a shared instance text parameter, and applied it to the nested families.  Once loaded into the host family, I linked that parameter to the host family's "Description" (which may not work for everybody, but works well for my situation).  Now I can schedule all of the components, and sort them in the schedule by their parent host family, which is, in essence, sorting them by the description of the host families.

The overall reason is that each of these nested objects has obviously a count, as well as a cost associated with them.  I wanted to be able to generate a list of components for each host family type that quantifies how many of each nested object it has, and what the overall cost for that host family will be - knowing that the cost of the nested families will be the same in each host family... make sense?

I don't see how you can do this with a regular family.  Have you looked at assemblies?
