This CityEngine example project contains a reconstruction of the Petronas Twin Towers in Kuala Lumpur, Malaysia. It provides different building attributes which can easily be changed to explore and create different design variations to the original building. The CGA rule file of this example makes extensive use of parametrized modeling including recursive rules to create the rotation symmetries and the vertical setbacks.
