explode To disassemble an import symbol (which represents imported geometry) into its next highest level
of elements. See Exploding Imported Geometry on page 1404.
export To convert information from a Revit project to another format, for use with another software
application. For more information, see Export on page 1341.
extend To lengthen selected elements to meet a specified boundary. See Trimming and Extending Elements
on page 390.
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 1388 and Exploding Imported Geometry on page
1404.
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 an Extrusion on page 320.
You can also create a void extrusion by cutting a shape out of a 3D solid. See Creating an Extrusion on page
320.
