Is Reference Specifies whether a reference plane, sketched during the creation of a family, is a reference in a project. This means that you can dimension to the family or align to it. If you set a reference plane as a reference for all family types, then you can consistently dimension to that family type when you place it in your project. For example, you create a door family with 24", 30", and 36" types. For each type, you specify a reference plane as left. Then you place the new 24" door type in your project and dimension it 5' from an exterior wall. Then you decide to replace that 24" door with a 30" door. When you swap out the doors, Revit retains the 5' dimension. The Is Reference names are arbitrary and are meant as a convenient method for maintaining consistency across family types. For more information, including information on strong and weak references, see Defining Priorities for Reference Planes.
Defines Origin Specifies where the cursor rests on the object you are placing. For example, as you place a rectangular column, the cursor rests at the centerline of the column shape.
