[i_cagri782003]

I am working on a very huge project that is linked with multiple models. I am trying to create a door schedule with from/to room data in host model and it results blank for from and to data cells.

I am using revit 2017.1, include elements in links is checked when generating. all other data I extract is ok. Every idea will be appreciated because of a deadline i have in a couple of days.
