Design

Design Tools enable designers to test and compare spatial, environmental, and performance criteria directly within parametric models. The tools are divided into three categories: Road Tools, for generating and refining street geometry and sections; Parcel and Building Tools, for shaping parcels, extruding buildings, and managing design attributes; and Viewport Tools, for visualizing density, height, and other spatial performance metrics in real time.

Tip

These tools are flexible, allowing road detail inputs to be modified through the provided .csv input files. This enables users to customize parameters, update design assumptions, and test multiple scenarios without altering the core model logic.
