It is now possible to create IFC Classification References for ArchiCAD elements. If you wish
to use standard classification systems, you can use Predefined Rules for that, as discussed
in another clip.
It is also possible to create and use your own office classification system.
You can do this while having elements selected or not selected in the project.
If elements are selected, the created Classification References will apply only to the selected
elements. If no elements were selected, this will become the default, and all subsequently
created elements of that type will have this IFC Classification Reference.
In the Tags and Categories panel of any construction element type such as Walls, Slabs or Beams
etc., click the Manage IFC Properties button.
In the appearing subdialog, click the Create Property or Classification button at the bottom.
In the appearing Dialog, choose the Classification reference radio button and specify the name
you wish to give to this Reference. Then click the OK button.
Returning to the previous Dialog, the newly created Reference will be listed in the Classification
References group at the bottom of the list of IFC properties.
You can see a red cross icon before the name of this Reference and also before the Classification
References group. If you click the former, the given IFC Property will be deleted. If
you click the latter, all Classification References will be deleted for the given element type
or selected elements.
Now select this Reference and click the triple dot button in the middle. In the appearing
Dialog you can now set the values for the Classification Reference of the given element
type or its selected instances.
6 values are available and these are the same values that standard Predefined Rule-based
Classification Systems use. The most commonly used fields are normally the Item Reference and the Name fields.
Enter values with these two fields then click the OK button to accept these changes.
Then click the OK button again to return to the Settings Dialog.
The Classification Reference created is now
listed under IFC Properties in the Tags and Categories panel. Its provided value or
values are also shown and may be modified from here if needed.
Just as with other IFC Properties this new IFC Property can now be used in Find and Select
operations or in scheduling elements.
Click the OK button to accept all changes and leave the Dialog.
Please note that these Classification References can also be created from the IFC Manager Dialog.
