How to Create IFC File in AutoCAD

Understanding IFC Files and AutoCAD

IFC, or Industry Foundation Classes, is a standardized file format mainly used in Building Information Modeling (BIM). This format promotes interoperability among various BIM software, making it easier for professionals in architecture, engineering, and construction (AEC) to collaborate effectively.

Steps to Create an IFC File in AutoCAD 2025

Creating an IFC file in AutoCAD 2025 involves several steps. Follow this guide to ensure a successful export of your design:

  1. Open the Export Dialog
    Begin by launching AutoCAD 2025 and ensuring your project is open. Navigate to the top menu and select the File tab. From the dropdown, choose Export, and then select the IFC option.

  2. Configure Export Settings
    The Export to IFC dialog will appear. Here, you’ll specify various settings required for the export. Make sure to review and adjust the following properties:

    • File Name: Enter an appropriate name for the generated IFC file.
    • File Location: Click Browse to select a folder where you’d like to save the IFC file. Ensure that the path is easily accessible.
  3. Select Drawing Files
    In the dialog box, locate the section labeled Drawing Files. Here, you will select which drawing files you wish to include in the IFC export. Check the boxes next to the files intended for export.

  4. Choose IFC Setup
    Identify the setup you intend to use for the export. Under the Current selected setup, select the appropriate IFC setup based on your needs.

  5. Finalize Export
    After you’ve configured all necessary options, click the Save button to initiate the export process. AutoCAD will begin generating the IFC file which may take a few moments depending on the complexity of your project.

Discussing Compatibility of IFC with Other Programs

Various software programs support opening and utilizing IFC files. Notable options include:

  • Autodesk Revit
  • FME Desktop
  • GRAPHISOFT ARCHICAD
  • SketchUp (with appropriate plug-ins)

Common Methods to Convert DWG to IFC
