Identify the spaces and zones based on the requirements of the systems in the model.
Room bounding uses surfaces from the linked model to enclose spaces placed in areas in the model.
Place spaces throughout the model to account for the entire volume.
Spaces and zones maintain MEP information that can be used to define system requirements. Assign spaces to zones for the particular systems that you are designing.
With the model preparation completed, you are ready to determine system requirements in the model.
