Introduction
1. Main Functions
- Autogeneration of spatial models: by integrating urban planning logics and computer algorithms, UrbanXTools can rapidly generate rudimentary spatial models for urban design projects. The spatial model will be complied with superior plans and regulations.
- Assessment of urban design projects: UrbanXTools can provide instant assessment of urban design projects based on multi-disciplinary features and sustainable development goals.
- Construction of a feedback loop: by using parametric design methods, we aim to construct a mechanism for regulatory plans and urban design projects to get instant assessments, feedbacks and modifications. With this mechanism, the efficiency and quality of urban design could be enhanced
2. Objectives
- High quality
- Sustainable urban development

5. Notifications
- Rhino version 6.9 and above are recommended.
- Model unit MUST BE METER, and models cannot be generated if your model unit is millimeter (mm)
- Please put your geometric objects, such as roads and land parcels, near the origin of coordinates (0, 0, 0). Confined by computation accuracy of geometric objects in RhinoCommon, the geometric Boolean operation might go wrong if you put your model too faraway from the origin point.
- If you encounter any other problems or have any demands and suggestions, please let us know via Github Issues. We’ll try our best to help.
