1. When using the Add Instance Data tool, I noticed the data is added, but it does seem the Family and Part as defined in the DG Catalog Item isn't used.
Is there a reason for that? It's not logic you have to add the part later on yourself.
2. There is an option Use Model Properties, the help says:
"Enabled when the Can be placed as a cell property in Cell Properties is turned on.
Datagroup system data is placed with each cell instance (CEL, BXC) when on.
Datagroup system data is added to existing selected cells when on."
I have no idea what this means.
I think it has something to do with working in a model that is to be used as a cell?
What does it change to check/uncheck this option?
