Importing and Exporting IFC Files
Based on established, international standards for common objects in the building industry, the Industry Foundation
Classes (IFC) file format provides an interoperability solution between different software applications for reducing the
loss of information when files are transmitted.
AutoCAD Architecture is IFC-certified for importing and exporting version 2x3 IFC files. IFC files from versions 2x2
and 2x can also be imported if the data is compatible with 2x3 and is consistent with implementation agreements as
defined for the IFC 2x3 coordination view. For more detailed information, go to
http://www.iai-international.org
and
search for IfcWiki.
IFC certification enhances your ability to share project information across disciplines and technical applications over
the life of the project. For example, building models drawn in AutoCAD Architecture are saved to a DWG file format.
You can export the drawing using the IFC format to an IFC-certified application that could not otherwise open a DWG
file. Likewise, you can import an IFC file that was originally a format other than a DWG and work on that drawing in
AutoCAD Architecture.
Architectural Objects and IFC
Visual fidelity for 3D objects is maintained in model views. This means that dimensions are maintained for 3D objects
exported to IFC. Objects must be dimensionally accurate in the single IFC model because it is shared by diverse
applications.
As shown in the following table, most common building objects imported from an IFC file are created as the
corresponding AutoCAD Architecture objects in the resulting drawing file. However, in the case of an IFC object with
complex geometry that does not directly correspond to the components of its AutoCAD Architecture counterpart, a
custom display block is created in the model display representation. This may lead to some instances where the 3D
geometry in the model display representation does not correspond exactly to the plan display representation. For more
information, see “
Display Representations
” on page 451.
