  1. Install the BlenderBIM Add-on

    Open up Blender, and click on Edit > Preferences.


    Select the Add-ons tab, and press Install… on the top right. Navigate to the .zip you downloaded in Step 2, and press Install Add-on.



    You do not need to unzip the add-on file. You should install it as a zipped file.

    You should now see Import-Export: BlenderBIM available in your add-ons list. Enable the add-on by pressing the checkbox.


All done! Your interface will now look similar to below. If you check the File menu you should also see an option to Open IFC Project.

First follow the Uninstalling section below, then install the latest version.


Navigate to Edit > Preferences > Add-ons. Due to a limitation in Blender, you have to first disable the BlenderBIM Add-on in your Blender preferences by pressing the checkbox next to the add-on, then restart Blender. It is critical to follow this sequence of disabling first, and then restarting.

After restarting, you can uninstall the BlenderBIM Add-on by pressing the Remove button in the Blender preferences window.

Alternatively, you may uninstall manually by deleting the blenderbim directory in your Blender add-ons directory.


It is important to follow the sequence of disabling, restarting, then removing. If you do not restart Blender, the add-on will fail to remove correctly, and you will need to uninstall manually.

Where is the add-on installed?

Upon installation, the BlenderBIM Add-on is stored in the scripts/addons/blenderbim/ directory, within your Blender configuration folder. However, the location of your Blender configuration folder depends on how you have installed Blender.

If you downloaded Blender as a .zip file without running an installer, the BlenderBIM Add-on will be installed in the following directory, where X.XX is the Blender version:
