In building a custom translator for IFC publishing I would like to be able to export only the lights from a project to an IFC file. (reason being that I'm building a coordination model that is assembled in Tekla's BIMsight from sub-discipline models and we had to build the electrical model for the electrical engineer)
Unfortunately even though ArchiCAD allows us to tag an object with an Element Classification of "Light Fixture" there is no mapped IfcName that can be filtered in the IFC export settings.
I realise I could use the selected elements or by visible layer methods for saving out the files but what I am trying to set up is a structured publishing set of IFC sub models by discipline.
This would then enable us to publish part models of our shopping mall projects and issue smaller byDiscipline/byTrade IFC models to the consultant team that can then be reassembled in Tekla BIMsight or Revit or whatever. Similar to the "delta technology" BIM Server uses this would mean that if we changed a steel column setout in our ArchiCAD model we only have to re-issue the "IFC - Structural - Steel" model rather than the entire 200Mb+ whole of building IFC which takes ages to export then re-import to Revit etc.
I'd prefer not to have to create a "lights" layer and a "power outlet" layer and a "switchboard" layer and so on.
