Updated Free CityCAD Viewer released

CityCAD Viewer has been updated to version 2.2.1.

You can use CityCAD Viewer to open and explore URB-format city models. You can't draw any new blocks or streets (you need the full CityCAD application to do this), but you can view and explore models, extract diagrams and data, organize elements in different groups, and edit some basic land use, movement, environmental and appraisal settings.

CityCAD Viewer includes many of the same analysis features as CityCAD - for example shading according to distance to shops (above)

Do you want to share your CityCAD models with colleagues, clients or other stakeholders?

If they don't have a licensed copy of CityCAD, you can direct them to www.holisticcity.co.uk/downloads where they can download their own copy of CityCAD Viewer. Completely free of charge, and no need for a licence or activation codes - it just opens as soon as it's installed.

CityCAD 2.2 released with new data import engine

Holistic City Software has released CityCAD 2.2 with a new data import engine and improved 2d drawings, as well as several new features and further improvements in stability and performance.

Import data directly into your city model

The new data import feature is a key step in our longer term programme to extend interoperability with other software tools.

You can now import a CSV file or Excel spreadsheet, and automatically create custom parameters for elements in your model from the data. You can update existing parameters or create new ones as part of the import process.

The data import feature can also directly edit a number of CityCAD properties - for example if you have a spreadsheet with block names and number of storeys, this can be used to set the heights of the buildings in your CityCAD model. Densities, unit sizes, energy use and other parameters can also be updated automatically.

2D plan diagrams

We have improved the 2D Plan Diagram window, and you can now shade blocks, city items and routes separately. The new distance, liveability and custom parameter shading, which is already available in the 3D view, has been extended to the 2D view.

Perimeter objects, such as house models on semi-detached/detached housing blocks, can now be shaded separately to provide extra analysis and more descriptive figure-ground diagrams.

Specify unit density when editing land use subdivisions

When editing land use subdivisions in mixed-use blocks or city items, you can now specify a 'unit density' for each one, and this will automatically set the number of units.

Miscellaneous other minor improvements

  • The data export system has been improved 'under the hood' so you can now export your data to XLS format without needing to have Excel installed on your PC.
  • Shading has been improved, and we have introduced a new 'High Rise' option when shading by number of storeys, to improve legibility when there are many tall buildings.
  • New 'Purge Unused' button makes it easy to clear the File DXF Library of DXF City Items that are not used in your current CityCAD model.
  • New keyboard shortcuts to set snaps to default or narrow range.

As with all of our new releases, we have fixed known bugs and improved the speed and performance of CityCAD wherever possible. We have a policy of fixing reproduceable bugs as soon as possible after they are detected, and so please contact us at This email address is being protected from spambots.
