hosted component A model element that can exist in a building model only if sponsored by another (host)
element. Doors, windows, model lines, and components (such as furniture) are hosted components.
For more information, see Hosted Components on page 796.
i-drop An Autodesk feature that allows you to drag and drop content from a web page into a Revit session.
Using i-drop, designers and developers have the power to create web pages that can easily be dragged and
dropped into Autodesk design products that are i-drop enabled.
You can import CAD files into Revit Architecture using i-drop. See Importing CAD Files Using i-drop on
page 1389.
IFC See Industry Foundation Classes (IFC) on page 1492.
imperial The British Imperial System of weights and measures.
When you install Revit Architecture, you specify whether you want to use imperial units (feet and inches)
or metric units (meters and centimeters). You can also change the type of units used in a project. See Project
Units on page 502.
import To bring information from another source into a Revit project. For example, you can import DWG
files created using a CAD application (such as AutoCAD) into Revit Architecture. See Import/Link on page
1386.
import symbol A Revit element that contains all objects (such as blocks and xrefs) from an imported drawing.
When you move the cursor over the imported objects, Revit Architecture shows information about the
import symbol.
You can explode an import symbol to convert it into individual Revit elements. See Exploding Imported
Geometry on page 1404.
imported categories Categories of elements that are derived from an imported drawing. See Exploding
Imported Geometry on page 1404.
You can change the visibility and graphic display of imported categories. See Visibility and Graphic Display
in Project Views on page 198.
in-place family A family of elements that is created within the context of the current project. An in-place
family exists only in the project and cannot be loaded into other projects.
Using in-place families, you can create components that are unique to a project or components that reference
geometry within the project. For example, to create a reception desk that must fit between several other
items in a room, design the desk as an in-place furniture family. In a structural model, you might create an
in-place family for a thickened structural floor, or a wall extrusion that conforms to a uniquely shaped
architectural wall that it supports. If the original design ever changes, the in-place element changes
accordingly.
