# Revit IFC Open Source

Revit has an integrated IFC engine, which is also available as open-source through GitHub: <https://github.com/Autodesk/revit-IFC>&#x20;

Important Updates are included in regular Revit updates. Minor updates can be downloaded through [Autodesk Manage](https://manage.autodesk.com/home) or the [Github repository.](https://github.com/Autodesk/revit-ifc/releases/tag/IFC_v24.2.0)&#x20;

{% hint style="info" %}
Important: There is a separate installer for every version of Revit, and the installation also updates the Navisworks IFC engine.

The installation includes additional assets, such as the IFC Shared parameter files which are used to add common IFC properties to Revit. These are stored in C:\ProgramData\Autodesk\ ApplicationPlugins\IFC 20xx.bundle

More information about these files can be found in the following section:[ ](/revit/ifc-export-category-mapping/using-ifc-shared-parameters.md)[Using IFC Shared Parameters](/revit/ifc-export-category-mapping/using-ifc-shared-parameters.md)
