Export drawings to other IFC-certified applications, and import IFC files to create and work in DWG™ format. Industry Foundation Classes (IFC) file format provides an interoperability solution between different software applications. Using the IFC format, you can export drawings to other IFC-certified applications that could not otherwise open a DWG file. Likewise, you can import an IFC file to create and work in a DWG file that was originally created in a format other than DWG.
