Object-ID Generator

The user defined Object-ID is a major property for a building. The building generation workflow with building footprints (CityModeller) is using a footprint attribute as Object-ID and applies it to the resulting building object. The building generation without using building footprints (BuildingFinder) is generating the Object-ID with the Object-ID Generator automatically.

With the capturing functions in the 3D Editor it is possible to generate new building objects. To assign or update the Object-IDs automatically the Object-ID Generator tool is also available in the 3D Editor perspectives Tools menu.
