Thanks Eric... That sounds pretty much of what i needed...But before the GIS epic starts, i have found out that i need to do some clean up with the revit file to export to IFC and also that the IFC model/version 2X3 is what is being used for geographic capability...So i need to first understand the export process at revit side and then probably get a grip on the GIS side. But still, thanks alot for the reply... I will keep posting my progress
