core The structural part of a compound wall or other host element. When you use Revit Architecture to
design a compound wall, you specify the layers and materials that compose the core of the wall, as well as
the interior and exterior layers of the wall.
In the following illustration, the core is outlined in green in the wall preview. The layer list is where you
define and change the layers in and around the core.
When aligning or dimensioning the wall, you can choose to measure from the center of the core or from
the interior face or exterior face of the core. See Vertically Compound Walls on page 567 and Dimensioning
to Core in Compound Structures on page 226.
crop To limit the boundaries of a view, omitting parts of the building model from the view.
See also crop region.
crop region A user interface mechanism that defines the boundaries of a view. Elements in the building
model that are outside the crop region do not display in the view or on a sheet on which the view is placed.
In the following floor plan view, the inner, solid red line indicates the model crop region. The outer, dashed
red line indicates the annotation crop region. For more information, see Crop Regions on page 163.
