Export window IsExternal Revit 2023

If you export a window to IFC it will get the value IsExturnal is False in the Pset_WindowCommon properyset. With Doors you can set this yourself, but not with windows. How can you get this right in the Revit way (I know that I can add a parameter IsExternal, I'm concerned about the difference with the parameter "function" with which you can set the IsExternal True or False in Doors)

You can do this with a Parameter mapping Table

Create a txt file. Hereunder an example of what it should look like (spacing by TABs)

(Lines regarding Fire Rating are not relevant for you)

In Revit create a project parameter for windows (same name as in the txt file)

In Revit set IfcIsExternal to True or False for your windows

In the export to IFC load the parameter mapping table.

Result after export of the IFC

Please mention Revit version, especially when uploading Revit files.

Like @L.Maas says - add a Project Parameter. Also note there are quite a number of categories not having this IsExternal parameter, like Roof and Ceiling. So if you add the parameter for Windows, you might want to add it for those other categories as well. This is our list:

Then you also have to add to the the parameter mapping table to make sure that the IsExternal is coming in the right IFC (common) property set.

Hi, i used another method and it worked for me,

I created a new Type parameter called IsExternal as a Yes/No parameter.

As shown under :

When Exporting the Ifc file it worked just fine.

I'm in Revit 2022.1.6
