Ideate Query provides access to many kinds of properties available from the Revit model.
The properties include Revit system parameters defined for each category. Many of the built-in parameters are viewable with Revit Properties Palette.
See Revit menu: Modify Tab Properties Panel (Properties)
These properties include Project Parameters and Shared Parameters associated with user-selected categories in a Revit project.
See Revit menu: Manage Tab Setting Panel (Project Parameters)
These properties include Family Parameters (non-shared) and Shared Parameters associated with a particular Revit family.
See Revit menu: Family Editor Home Tab Properties Panel (Family Types)
NOTE: If more than one data category is selected within Ideate Query, the list of available properties will indicate "Multi-Category" as shown. In this mode the list of properties will be narrowed and will be limited to Project, Project Shared and System Parameters. To see more parameters, select only one of the data categories at the left.
