Supports in Revit have no property\u00a0Function<\/em> such as walls.\u00a0<\/p>\n

However, you can create your own parameter and take it into account during IFC export - the important thing is that it is a Yes\/No<\/em>\u00a0parameter, since the IFC property is also known as\u00a0boolean<\/em> is defined (see IFC documentation<\/a>).\u00a0<\/p>\n

This parameter then only needs to be assigned correctly with the parameter assignment table during export.\u00a0<\/p>\n

Example with parameters\u00a0Outside<\/em>:\u00a0<\/p>\n

\"\"<\/a>\"\"<\/a><\/p>\n

\u00a0<\/p>\n

\u00a0<\/p>\n

\u00a0<\/p>\n

\u00a0<\/p>\n

\u00a0<\/p>\n

\u00a0<\/p>\n

The parameter mapping file is a simple text file (UTF-8 format) with the following syntax:\u00a0<\/p>\n

IFC Pset Name IFC Property Name of the Revit property<\/em><\/p>\n

In the example above:\u00a0<\/p>\n

Pset_ColumnCommon IsExternal Outside<\/em><\/p>\n

Important:\u00a0
- the spelling must correspond exactly to the spelling in the IFC documentation, also with regard to capitalization
- The value in Revit must be available \/ box must not be grayed out\u00a0<\/p>\n

The standard parameter is now filled correctly when exporting:\u00a0<\/p>\n
