About Using Property Set Definition Samples

When exporting an AutoCAD Architecture 2022 toolset model as an IFC file or importing an IFC file into AutoCAD Architecture 2022 toolset, some of the object attributes in IFC entities cannot be mapped directly to AutoCAD Architecture 2022 toolset object properties.

The property set definition sample has a set of IFC object attributes (style and object type) applied to AutoCAD Architecture 2022 toolset objects. This allows you to set the required values in the property sets used for exporting IFC files. These values are exported without any extra processing or interpretation.

During import, the same property set definition is used to capture and preserve IFC object attributes that cannot be mapped directly in the AutoCAD Architecture 2022 toolset properties.

This template can be found in the following location: C:\ProgramData\Autodesk\ACA <version>\enu\Styles\IFC_Object_Attribute_Pset_definition.dwg.

In the property set definition template:

• Only simple attributes are listed.
• IFC object attributes that can be mapped directly to AutoCAD Architecture 2022 toolset object properties during the IFC export process are not defined in the template.
