Overlapping Mass Faces
In the project environment, any joined and overlapping mass faces split into 2 faces: interior and exterior.
This allows you to create interior or exterior hosts by face.
In the following illustration, 2 masses are joined, and the overlapping faces have 2 different hosts. The
exterior face has a curtain system by face. The interior face has a wall by face with a door.
When you join masses, the area of the inner wall shared by the masses is deducted from the gross surface
area for each mass. If you create mass floors, this inner wall area is also deducted from the exterior surface
area for each mass floor.
The perimeter of a mass floor, however, includes the entire perimeter, even when it overlaps the perimeter
of a mass floor in an adjacent joined mass.
Mass Instances in Design Options, Phases, and Worksets
You can assign mass instances to any workset, range of phases, and design options. Consider the following
limitations:
■
If you want to join geometry of 2 masses and then vary the relationships in different options, you must
copy both masses into each option.
■ If you want to modify relationships between 2 masses and they are in different worksets, either both
worksets must be editable, or you will need to borrow one or both of the masses from the owners of their
worksets.
■ If the relationships between masses vary from phase to phase, you may need to include each mass in
each phase.
