Assemblies for Generic Model families and nested families using <Family Type>

[Rab_i]

Apparently, any shared nested families using <Family Type> parameters don't show up in Assembly views in Revit. After the assemblies are created only nested families that are not controlled by <Family Type> shows up in views. 

These seem to be Autodesk Revit's inability or lacking function to process nested shared families and <Family Type> parameter. Perhaps if someone from Autodesk contacts me directly, I can show the issues I am running into. Unfortunately, I can't share the families here. 

Other issues regarding thumbnail view in Revit Properties window is similar.

The trick is that you need to use TAB to select both the parent family AND the nested/shared family when you create an Assembly.  Then they will show.

Thank you, Toan, for the right direction. Apparently, I had to select the family types that have actual geometries for Assemblies to work. I believe this is going to be true for thumbnails (Revit Properties window) and Dynamo importing geometries. Families that work like framework families don't make thumbnails in Revit properties window and in Dynamo imports. Seems like limitations to me.

The families I have are Generic Model Families with Structural Framing Families nested 2 levels. Meaning, Structural Framing family is nested into Generic Model family and then that Generic Model Family is nested into the framework Generic Model family which drives them using <Family Type> parameters.

Thanks again for the notes.

That is exactly the stuff you do not want to do. For this reason nested family was used, so Revit should automatically read alll the nested elements into the assembly instead of selecting each family separatedly.
