Supported IFC Classes

Before exporting a Revit Architecture project to IFC, make sure that Revit Architecture supports the desired
IFC classes. To see a complete list of classes, use the following procedure.
To see a list of supported IFC classes

The IFC Class Name column lists the supported IFC classes.

Loading and Modifying an IFC Mapping File

Before exporting a Revit Architecture project to IFC, you may need to map generic family instances to IFC
containers (element types). You do this by creating a new IFC mapping file or editing an existing one. Also,
you can use the following procedure to load the desired IFC mapping file before exporting a Revit Architecture
project to IFC.
To load and modify an IFC mapping file
1 Click File menu
2 Do either of the following:
To create a new IFC mapping file based on the IAI standard, click Standard.
Revit Architecture creates an IFC mapping file named exportlayers-ifc-IAI.txt.
To load an existing IFC mapping file, click Load, navigate to the file, and click Open.
In the IFC Export Classes dialog, each row represents an element category or subcategory. For
standard building elements, an assigned class name appears in the IFC Class Name column. For
building elements that do not have automatic mapping to IFC export classes, "Not Exported"
appears in the IFC Class Name column.
3 For each category or subcategory to export, do the following:
For IFC Class Name, enter the name of the IFC class for the particular category/sub-category
pair.
For Type, enter the type of object within that subclass.
Appropriate values are set according to the IFC standard definition. Selecting Not Exported
prevents elements of that category or sub-category from being exported.
If the values for a category or subcategory are blank, Revit Architecture will try to determine the
appropriate category. If it cannot make a match and the object has geometry, it is exported as
a proxy object.
4 To save the settings, do one of the following:
To save the settings in a new IFC mapping file, click Save As, navigate to a target folder, and
enter a new file name. Click OK.
To save the changed settings in the existing IFC mapping file (whose file name appears in
the dialog s title bar), click OK.
When you export a Revit Architecture project to IFC, Revit Architecture automatically uses the appropriate
IFC mapping file.
