The project elements overview lists the different elements that are used in the BIM Model project such as interior and exterior walls, curtain walls, storefronts, doors, windows, floors, ceilings and hardware.  Selecting an element allows for specific product configurations of that element.

Elements are broken up into the product divisions such as Division 8 for storefront, curtain wall and windows.  Then listed as each elevation or sequence of parts.  At any time, you can see where the product is in the BIM by clicking on the EYE icon.

Make your product selections, then export the product details back into your BIM Model.
