FAQ: Why are the property sets unavailable when I try to add a column?

Property sets are listed only if property set definitions are stored in the current drawing. Also, only property sets that apply to all the objects you selected on the Applies To tab are available to use in schedule table columns. A property set that applies only to some of the selected objects cannot be included in the schedule table. For example, a window schedule that applies to windows and window assemblies cannot contain columns for properties that apply only to window assemblies.
