Use this procedure to include automatic property data in your PDF.
All automatic properties associated with the objects you have selected for exporting are published to the PDF file.
By default, the automatic property data exported will be listed under a property group called Aec+<object type>. For example, if you export the automatic properties of a door, they will be listed under AecDoor. If you are exporting additional user-defined property set definitions and one of them already uses the name Aec+<object type>, the automatic properties will be listed in a property group called Aec+<object type> (2). In the door example that would mean that if you are exporting a user-defined property set definition named AecDoor, then the automatic door properties will be listed under AecDoor (2).
If an object property is both an automatic property and is also included in a property set definition, it will be listed both under the automatic properties and under the property set definition it is part of in the PDF file.
