Block / City Item shading

Default Shading

In the Main Display Window, by default the Blocks are coloured according to their land use.

Instead of this, you can choose to shade the blocks and City Items depending on several attributes. To customize shading colours, you can go to the Preferences window.

Choose View Menu: Block/City Item Shading... and a panel will appear:

Click on the drop-down menu to choose from several variables, and press Enter when finished. All blocks and city items in the model will then be shaded according to that variable - a key is provided in the Legend panel.

The shading will update dynamically if you modify the model in a way that changes the variable. For example, if you shade the blocks and city items according to 'Net Residential Density' and then increase the number of units in a block, then the colour shading will update accordingly.

Block Values vs Floor/Subdivision Values

You can select either one of these options:

Note this means that values that relate to the block only are not included when the shading is calculated. For example, if you shade according to appraisal costs or values, then any cost or value which is applied to the block as a whole, instead of to a floor or subdivision, will not be included.)


Block Shading can be useful for quickly identifying problems and opportunities in your city model.

For example, you can choose 'Net Car Parking' and immediately identify where there is a surplus or deficit of parking spaces, or shade according to 'CO2 Emissions' and see instantly which parts of the masterplan are causing the highest emissions.

Remember you can also shade according to Custom Parameters. If you want to visualize data quickly, you may be able to import the data, apply it to elements in your CityCAD model, and then shade accordingly.
