Notice tjtorial in the scene, there is already a small test shape layer Footprint that we can use as a locator indicated in green in the next screenshot to place a building. Selection type Result Single click.
The CityEngine Scene dialog box appears. Essential Skills project, which you should already have linked to your workspace.
This subdivision scheme can be implemented in the CGA shape grammar as follows: The result of this section will look like the following image: We now can dig deeper and work out more details, with more precisely placed buildings and better overall designs. The default folders that store your project data, such as assets, rules, and scenes, are already present, though empty.
Next, you’ll create a new scene. Selects a single object.
In the next section, you’ll add random variation to your simple buildings. The actual asset is loaded from the project’s assets folder in the Navigator. You’ll use textured planes instead of the complex window asset.

Select Objects of Same Group: Add a new attribute LOD to the existing attributes in the. Now you’ll copy all necessary files from the downloaded Tutorial 1 project into your new project. It should look similar to the following screen shot: The subdivision split is performed in the same way to assure that the floor heights are in sync with the front facade.
The Grow Streets dialog box appears.

The left-to-right rectangular selection is usually used to select tiny objects such as single Street Graph Nodes when there are many objects occupying the same space. The building now has a random height value of For this purpose, we are using a fictitious example of a development area with nine building plots in the center of a city.
The following figures depict the extruded mass model first and the described decomposition into floors and tiles below. If the dimensions are not set the same as the Window or Door rule, the sizes are adapted automatically—otherwise the given dimensions are used.
While the Selection Tool is active, press Ctrl and Shift to either add or subtract from your selection. You can drive the building’s total height and then design the building minimally by cutting away one part of the building. Selects all objects completely within the selection rectangle. What this simplified example covers in about two hours would take several months up to several years in reality. The following image shows the rule set applied to arbitrary mass models: In this tutorial, the rules are already provided.
In this example, you’ll define the following two levels of detail:. Using the operation s x,y,zthe size of the scope can be set in the Wall rule. Now we are ready to zoom in further and design the exterior space our attempt on landscape architecture right at the entrance of the development area. Approximately streets were created, but you can’t see them all in the viewport until you frame the view.
CityEngine is particularly well suited to deal with such processes of iterative nature. Examining your current model, you’ll see that you can save polygons mainly on the window assets. We can now easily customize the design by changing the attributes in the Inspector. Putting all of these rules together, you get the final untextured simple building: Feedback-loops with clients are easily managed by sharing the proposed design options via CityEngine WebScene.
As you will see, CityEngine can be used in multiple contexts, disciplines, and planning phases for your projects. The z dimension is set to Same start rule on all visible layers. In this section, you’ll learn how to apply textures to window and wall elements of the simple building. The Groundfloor rule refines the groundfloor shape with a similar subdivision split, with the difference that an entrance is placed on the right.
Select Objects with Same Start Rule: The modes are also listed in the Selection Tool submenu in the toolbar. Start Rule—Defines the first rule that is executed within the rule file.
This section looks at the different navigation schemes available. Once you manually change attributes in the Inspector it will become bold and override the definitions of the rule. Building attributes are typically defined at the beginning of cityenginr rule file although they can be put anywhere in the rule file.
Tutorial 16: Urban planning
New variations of the buildings can be created by changing the seed value. A new project is created and appears in the Navigator by default, located in the upper left corner of the CityEngine window. The Floor rule is a typical example of the subdivision of a floor into tiles of an approximate width of 3. To get a correct value, we input the area of the plot the building occupies. The simple building you already modeled will be your high resolution model.
The mass model is created with the extrude operation as follows:.
