[019] How to Generate Real-Time Building Reports in CityEngine Using CGA

Image
Extract + Real-Time Data + Procedural Modeling Metrics Learn how to use the report command in Esri CityEngine to extract live statistical data such as floor counts, total floor area, and land-use metrics directly from your procedural models. When working on complex urban models in Esri CityEngine , you might have wondered: "Is it possible to get statistics on the number of buildings, the area per land use, or the total count of windows in real time?" The answer is yes. By using the report command in your CGA rules, you can display live information in the Reports tab of the Inspector panel. This data can then be easily copied into a spreadsheet for detailed analysis and reporting. The Core Concept of the Report Command The fundamental idea behind the report function is to instruct CityEngine to record specific information at a chosen stage of your rule hierarchy. Even if you are a beginner at CGA, ...

[009] How to Generate Basic Streets in CityEngine

Image
Learn how to generate basic streets in Esri CityEngine using the Street Creation tool. The built-in Street tool is best for conceptual networks rather than highly detailed engineering blueprints. Its greatest value lies in automatically dividing geometry into 'Street', 'Sidewalk', and 'Joint' shapes, which act as immediate triggers for your CGA rules. This tutorial covers how to create street networks, adjust sidewalk width, and understand Start Rules (Street, Sidewalk, Joint) for CGA-based procedural modeling. The Street Creation tool is arguably one of the most frustrating features in CityEngine. However, it contains fundamental concepts you must understand before diving into CGA coding, so we need to cover it briefly. First, let me explain why it can be frustrating: it is terrible at handling highly curved or sloped roads. It is incredibly difficult to perfectly replicate a complex, real-world en...
