CityCAD Viewer

A Complete Guide to Viewing and Sharing Urban Data in CityCAD Viewer

CityCAD Viewer is a powerful, free utility designed to democratize access to complex urban design models. While urban planners and architects use the full version of CityCAD to create intricate, data-rich 3D city layouts, stakeholders often only need to review and analyze the results. This guide explains how to navigate, analyze, and share urban data effectively using CityCAD Viewer. Understanding CityCAD Viewer

CityCAD Viewer allows anyone to open native CityCAD files (.ccdf) without purchasing a full software license. It is not just a passive 3D model viewer. It retains the underlying intelligence of the urban model, meaning every building, road, and land use zone remains attached to its live quantitative data. Key Features for Data Inspection

When you open a model in the Viewer, you have access to several sophisticated tools to inspect the urban data:

Live Sustainability and Financial Metrics: As you explore the model, you can view integrated spreadsheets and charts displaying total floor areas, residential unit counts, car parking ratios, estimated energy consumption, and carbon emissions.

Thematic Mapping: You can shade the 3D model based on specific attributes, such as land use type, building heights, or construction phases, making complex datasets instantly understandable.

Component-Level Inspection: Clicking on any individual building or street opens its properties panel, revealing specific data like commercial floorspace, residential densities, and cost assumptions. Navigating the 3D Environment

To view the data accurately, you must master the spatial navigation tools:

Orbiting: Hold the right mouse button and drag to rotate the camera around a central point.

Panning: Hold the middle mouse button (or scroll wheel) and drag to move horizontally across the master plan.

Zooming: Scroll the mouse wheel up and down to move closer to or further from specific blocks.

Pre-set Views: Use the views menu to instantly switch between standard orthogonal perspectives (Top, North, South) or custom camera angles saved by the original designer. Best Practices for Sharing Urban Data

CityCAD Viewer transforms how planning teams communicate with clients, local authorities, and the public. To maximize the efficiency of your data sharing, implement these strategies:

Embed Camera Positions: Before sharing a file, the author should save specific camera angles matching key milestones or contentious areas of the project. This guides the Viewer user directly to critical locations.

Utilize Phases: Ensure the model uses CityCAD’s phasing tool. Recipients using the Viewer can then use a simple slider to watch the city grow over time, tracking how data shifts from Phase 1 to completion.

Keep Data Organized: Ensure all land use categories and custom variables are clearly named before distribution, as Viewer users cannot rename or restructure the data framework.

By leveraging CityCAD Viewer, project teams can eliminate communication silos, reduce the need for static 2D PDF reports, and ensure that every stakeholder makes decisions based on accurate, live urban data.
