cut volume The amount of material that must be excavated and removed from a site to prepare it for
construction. For example, in the following drawing, the red area indicates the cut volume, and the blue
area indicates the fill volume required to level the site for a building. See Reporting Cut and Fill Volumes
on a Site on page 901.
cutback The calculated adjustment in beam geometry that ensures beam ends meet without overlaying one
another at a join. This is the visible gap seen in a steel beam connection within the Revit project.
See Beam Cutback on page 782.
D
datum A non-physical item that is used to establish project context. Also called a datum element. Datum
elements include levels, grids, and reference planes.
For example, the following image shows a grid, which is used for the placement of columns and other model
elements. The grid is not a part of the building (such as a wall or a roof) but is used in a view to help design
the building.
Compare with annotation on page 1370 and model element on page 1424. For more information, see Annotating
and Detailing on page 1027.
