To get more out of extracting quantities from the Revit BIM model, Customised properties are created. Custom properties are similar to Revit’s project parameters, but can be created and edited by Arquimedes users and are applied to all categories. These custom properties can be applied to types or elements. This new tool can be accessed from the options button 
in the Assign items and quantity extraction window.
The definition of Customised properties can be shared between different linked Revit projects within the same Arquimedes project (but not their values).
Customised properties can be used:
- In combinations to obtain quantity details.
- In quantity filters.
- In subtype discriminators.
Customised properties can be displayed and their values edited in:
- The element list columns.
- The Type and Element properties window.
