Manage IFC property selection definitions

DB tool > Management tab > IFC group >  IFC properties menu > IFC property selection definitions

The property selection definition is a management object that includes the export definitions for property sets and properties: the information about the related property sets that need to be exported to IFC, and the information about the properties to be exported for each type definition when IFC properties are to be exported by device types.

This management object itself is not exported to IFC.

The global filter makes it possible to search for information using freely defined criteria, without taking wildcard characters * or ? into account. Furthermore, you can group and filter the information.

The items in different databases and functions related to them are divided on tabs:

  • Standard databases holds the default property selection definitions provided with the application which will be overwritten whenever the application is updated. You can copy property selection definitions from this tab to your own shared databases.

    • Open – Open the selected property selection definition for viewing or editing. By clicking the button, you can copy the definition to Shared databases.

    • Copy to shared – Create a copy of the selected property selection definition to Shared databases. Edit the properties as necessary.

      Select/Edit opens the IFC property set selection dialog where you can select the property sets to be included in the property selection definition.

    • Add to project – Add the selected property selection definitions to the project. Alternatively, add a property selection definition by double-clicking it.
