Hi Mutiara,
If it isn't telling you the ID to help you narrow the search down, use the marquee tool to enclose half the building, then show only that in 3d. If the error doesn't appear then you know it is somewhere in the other half. Keep repeating this until you have found the object/piece of geometry.
It might be a door or window that is causing the error, so if you have several that are identical in the project, you could try temporarily deleting them all and see if the error stops.
Good luck!
