A Room Calculation Point setting has been added to all family types that are room-aware, e.g., furniture, doors, casework, specialty equip, generic models. When these families are placed in a project, sometimes portions of their geometry are located outside a room, space, or within another element, which results in no calculable values being reported. Enabling the Room Calculation Point enables you to move the location of the calculation point to fall inside the required space.
The room calculation points also have to/from room functionality for doors so the you can better control how the door calculates which side is the To side and From side.
In Summary: You can improve design accuracy and ensure room/space calculations account for all elements for more accurate energy analysis.
