How can I use Revit and IFC properties in my model?

The Breakdown Table shows a traditional Revit Breakdown structure (Category - Family - ElementType - Extra Properties) by default. You can change it by adding additional new parameters for the relevant group.

The elements will be grouped by the values of the selected property once added.
Then you can change the breakdown structure by dragging and dropping the properties added to the appropriate position.
