compound wall A wall that consists of multiple vertical layers. Each layer can use a different material (such
as concrete, insulation, and interior finish) and have a different function (such as structure, thermal layer,
and substrate). See Vertically Compound Walls on page 639.
computer-aided design (CAD) The use of computer-based tools that assist engineers, architects, and other
design professionals in their design work.
conceptual design environment A type of family editor that uses geometric form-making and direct
manipulation tools to create in-place and loadable mass family elements.
constraint A parameter that defines a relationship between elements in a building design. For example, you
can specify the top constraint for a wall as Level 2. If Level 2 moves upward, the height of the wall increases
to maintain the relationship.
For more information, see Constraints on page 300.
construction document A document that communicates a building design to builders and contractors, so
they can create the building.
Revit Architecture generates construction documents using the information about the building model stored
in the project file, along with user-added annotation, detailing, and layout information. For more information,
see Preparing Construction Documents on page 1029.
