Convert IFC to XML

Understanding IFC and XML file formats

IFC (Industry Foundation Classes) is an open, neutral data format used in Building Information Modeling (BIM) to facilitate interoperability between different software applications in the architecture, engineering, and construction (AEC) industry. IFC files typically have the .ifc extension and store detailed information about building elements, geometry, and relationships.

XML (eXtensible Markup Language) is a flexible, text-based format for structuring and exchanging data. XML files use the .xml extension and are widely used for data storage, configuration, and communication between systems due to their readability and compatibility.

Why convert IFC to XML?

Converting IFC to XML allows BIM data to be integrated with other systems, such as databases, web services, or custom applications that utilize XML for data exchange. This conversion enhances interoperability and enables easier data manipulation and analysis outside of BIM-specific tools.

How to convert IFC to XML

There are several methods and tools available for converting IFC files to XML format. The process typically involves parsing the IFC file and exporting its data structure into an XML schema.

Recommended software for IFC to XML conversion

• IfcOpenShell: An open-source library and set of tools for working with IFC files. It includes IfcConvert, a command-line utility that can export IFC data to various formats, including XML. You can use it by running a command like IfcConvert input.ifc output.xml.
• BIM Vision: A free IFC model viewer that supports plugins. The XML Exporter plugin allows you to export IFC data to XML. Use File → Export → XML after installing the plugin.
• Revit (with plugins): Autodesk Revit can import IFC files and, with the help of add-ins or Dynamo scripts, export data to XML. Use File → Export and select the appropriate plugin or script for XML output.

Step-by-step conversion example using IfcOpenShell

1. Download and install IfcOpenShell from the official website.
2. Open a command prompt or terminal window.
3. Run the command: IfcConvert yourfile.ifc yourfile.xml
4. Check the output directory for the generated XML file.

Tips for successful conversion

• Ensure your IFC file is valid and not corrupted before conversion.
• Review the resulting XML file to confirm that all necessary data has been exported.
• Some tools allow customization of the XML schema; adjust settings as needed for your workflow.

Conclusion

Converting IFC to XML is a practical way to leverage BIM data in broader IT environments. Tools like IfcOpenShell and BIM Vision make the process straightforward, enabling seamless data exchange and integration.
