IFC Property Sets

Before you save a model to an IFC file, you can add IFC property sets for objects. In an IFC property set, you can define property data that you want to transfer to an IFC file with the object. There are different types of IFC property set: IFC standard common property sets, Vertex property sets and User-defined property sets.

You can select the property sets to be transferred when converting a model to an IFC file.

IFC Standard Common Property Sets

You do not need to add the IFC standard common property sets object-specifically. It is enough to simply select IFC Standard Common Property Sets when starting the conversion. The IFC standard common property set are fixed property sets. The user cannot affect their contents.

Vertex Property Sets

You can add Vertex property sets for objects. You can use pre-defined property sets, or add new, custom-specific Vertex property sets to the library. For custom-specific Vertex property sets, you can select the object type’s property data to be transferred. When converting a model to an IFC file, select Vertex property sets, when you want to transfer the property data of objects according to the Vertex property sets.

User-defined Property Sets

You can add new, user-defined property data for an object. The user-defined property sets are added directly for an object, they are not added to the library. For example, you can add a fixed value in text format for an object. This way, you can export any property data with the object to an IFC file. When converting a model to an IFC file, select User defined property sets, when you want to transfer the object-specific property data you have defined to an IFC file.
