What is CityCAD? A Beginner’s Guide to Urban Design

CityCAD by Holistic City allows urban planners and developers to design better neighborhoods faster by integrating 3D parametric layout tools with real-time quantitative impact analysis. Unlike traditional CAD tools that require tedious, manual tracing and recalculation for every minor layout revision, CityCAD updates the entire master plan dynamically. Real-Time Parametric Engine

The core driver behind CityCAD’s speed is its intelligent parametric object model, which establishes structural rules for urban environments:

Dynamic Street-Block Relationship: When a user sketches a street centerline, CityCAD automatically builds the complete streetscape, including pavements, sidewalks, setbacks, and street trees.

Automatic Block Generation: Enclosing an area with streets instantly creates an interactive urban block.

Instant Recalculations: Moving a street centerline stretches or compresses adjacent blocks instantly. The platform automatically recalculates total gross floor areas, dwelling units, and parking provisions in real time. Accelerated Scenario Testing

Instead of waiting days for engineering and finance teams to analyze a concept, planners can test multiple layouts in minutes:

Pre-Set Typologies: Users can instantly toggle blocks between various built forms, such as detached houses, perimeter blocks, or high-density mixed-use commercial buildings.

Live Financial & Cost Feasibility: Ballpark costs and development values can be tied to building units, enabling rapid commercial viability checks during early-stage planning.

Embedded Environmental Modeling: The software instantly calculates operational carbon, embodied carbon, energy needs, water consumption, and waste generation as the 3D model changes. Built-In Liveability and Planning Compliance

CityCAD includes a dedicated Advisor Panel that serves as a continuous, automated peer review during the design process:

Custom Threshold Alerts: Designers can establish strict rules for maximum building heights or density limits, receiving instant warnings if a layout violates zoning laws.

Proximity Analytics: The tool calculates average and maximum pedestrian walking distances to transit stops, schools, and green spaces, ensuring compliance with 15-minute neighborhood frameworks.

Urban Design Database: Planners can query thousands of real-world urban layouts inside the app to match exact street widths or housing configurations.
