Finally, designers can adjust the result in detail by employing real-time calculation and interactive operation. After integrating design factors such as an environment, transportation, and vision and summarizing the intentions of blocks and buildings in corresponding functions and control indexes, the initial generation plan was built by applying the obtained characteristics and procedural rules in specific shape grammar. New technologies play an increasingly important role in the analysis, monitoring, restoration, and. Furthermore, in a real urban design case located in Nanjing, this work applies the method to construct a three-dimensional scene quickly and accurately. With the top-down control by rules and bottom-up generation by shape grammar in CityEngine, the texture of the block can be generated as close to the actual block as possible. The CityEngine had been previously developed for the production of city-like structures 3. Second, the relevant composition patterns and parameters were employed as features for classification and were converted into procedural rules. The characteristics of blocks case samples in Nanjing are extracted as text descriptions. First, this study adapted the hierarchical structure and access structure theory to analyze the spatial form of target blocks. The implemented framework was tested in an urban design practice. This research implemented a framework of digital description and generative grammar of block form from the perspective of block morphological complexity. The need for efficient analysis tools and rational design methods represent ongoing concerns, while practicable and maneuverable applications rather than experimental studies are scarce. The significant challenges that urban design faces when moving forward into this new digital era involve the increasingly massive and complex projects that must be analyzed and developed.
