Ruler tool

The Ruler Tool is used to measure indicative distances in the Main Display Window. This can be useful if you want to quickly check measurements such as the depth of a building, or the size of a courtyard in a perimeter block.

You can choose the Ruler Tool by clicking on the Ruler Tool button on the CityCAD Toolbar.

Alternatively, if you are working in the Main Display Window and the last mouse click you made was in the 3D window, then press the keyboard shortcut 'U' to choose the select tool.

Drawing Rulers

Drawing a Ruler Quickly

The method for drawing a ruler is exactly the same as for drawing routes withe the Route tool. However, you can only draw one ruler, and if you start to draw a second ruler, or select another tool, then the ruler will disappear.

Click and drag from any point - the ruler will appear as you move the mouse cursor. The length of the ruler you are drawing will appear in white text next to the mouse cursor. When you have positioned the mouse cursor at the desired end point of the ruler, release the mouse button and the route will be displayed.
