export To convert information from a Revit project to another format, for use with another software
application. For more information, see Export on page 1273.
extend To lengthen selected elements to meet a specified boundary. See Trimming and Extending Elements
on page 316.
exterior The outside of a building, or the outside face of a surface.
external reference An AutoCAD mechanism that allows the architect to reference other drawing files in an
AutoCAD-based project. Also referred to as an xref.
See Implications of Importing vs. Linking for Xrefs on page 1307 and Exploding Imported Geometry on page
1322.
extrusion A method of defining 3D geometry for a building model.
You begin a solid extrusion by sketching 2D shapes on a plane. Revit Architecture then extrudes the sketch
between a start point and an endpoint. See Creating Solid Extrusions on page 386.
You can also create a void extrusion by cutting a shape out of a 3D solid. See Void Extrusions on page 390.
F
face A surface of a model element or mass.
You can apply paint, materials, and textures to each face of a model element (such as a wall). These details
display when you render an image of the building model. See Applying a Material to an Element on page
338.
You can use mass faces as the basis for creating walls, roofs, curtain systems, and floors in a building model.
The following image shows a mass face that is being used to create a wall. See Creating Building Elements
from Mass Instances on page 543.
