Industry Foundation Classes (IFC) A file format developed by the International Alliance for Interoperability
(IAI). IFC provides an interoperability solution between IFC-compatible software applications in the
construction and facilities management industry. The format has established, international standards to
import and export building objects and their properties.
Revit Architecture provides IFC import and export based on the latest IAI IFC data exchange standard. When
you export a Revit building model to IFC format, the information can be used directly by other building
specialists, such as structural and building services engineers.
For more information about Revit Architecture and IFC, see Exporting to Industry Foundation Classes (IFC)
on page 1292 and Importing Industry Foundation Class (IFC) Files on page 1317.
For more information about the IFC file format, go to http://www.iai-international.org .
infill element An insert that fills (patches) a hole in a host element after changes are made during different
phases of a building project. For example, if you remove a window from a wall during a demolition phase,
Revit Architecture fills the hole with an infill element. By default, the infill element has the same properties
as the host element (the wall).
The following illustration shows a demolished window that has become an infill element. See Infill Elements
for Phasing on page 1267.

demolished window
instance An individual occurrence of an element.
For example, when you place a wall in a building model, the wall is an instance of the wall type. If you
change parameters for the wall instance, the changes affect only that wall. If you change parameters for the
wall type, the changes affect all walls (instances) of that type, including existing walls and new walls that
you create in the future.
instance parameters Settings that control the appearance or behavior of an individual element in a project.
The instance parameters and type parameters of an element combine to establish its element properties.
Instance parameters are also called instance properties.
