# Revit IFC Open Source Revit has an integrated IFC engine, which is also available as open-source through GitHub: 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)
{% 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) {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
