Hello
@Darshan Rajaram Kamat and
@Jari JuntunenThank you for your answers but unfortunatly these really don't work for me.
I have several projects and in each projects several IFC models that are updated each week.
I really can't spend time everyday to carefully select new objects in each models to add the customs properties.
It seems essential to be able to quickly add properties that automatically propagate to an entire model, and also to the future versions of this model.
Just like in Tekla Structure or in Revit, when we add customs attributes, we don't have to add them manually to each instance of any new objects created, that would be quite tedious...
I hope you will implement this quickly.
Regards,
Olivier
