The CityEngine Scene dialog box appears. This subdivision scheme can be implemented in the CGA shape grammar as follows: Of course, this is only a very coarse design approach, but it gives us a ball-park number for the FAR very quickly. Here are the defined conditions:. Many people may find this quite intuitive and more flexible, especially for small to medium-sized contexts.
This way, the windows and textures are set back 0. Now that we have set a starting point in the zoning regulations, we can start looking at the schematic design for the complete development area. The following image shows the final building model: Download items Model a simple building Texture the simple building Add level of detail Random variation of building attributes.
Same rule file assigned on all visible layers. A new project is created and appears in the Navigator by default, located in the upper left corner of the CityEngine window. Later in this tutorial, you’ll need rule files and assets for the generation of the building models.

We hope this tutorial, however, has been helpful and has demonstrated the many ways in which CityEngine can be used in your city planning scenarios. The width and height of the scope are not affected since relative coordinates are used: Selects all objects completely within the selection rectangle.
Same start rule on all visible layers. Explore the provided rule you’ve been using so far. Typically in this step, a mass model can be divided into its facades by applying the component split.
Tutorial 16: Urban planning
For window and door elements, you only set the colormap to the desired texture. Since writing custom distribution rules for building placement patterns can result in quite complex CGA code, we propose in this tutorial to simply use either point shapes or manually created footprint shapes of any form, as a faster way to control the footprint distribution.
The brick texture channel 0 will be repeated every 1.
In this tutorial, the rules are already provided. The typical facade modeling workflow is as follows: The simple building you already modeled will be your high resolution model. This results in a front shape usually the main front facade with entranceseveral side shapes as facades, and a roof cittyengine. We have prepared an initial layout with a mixture of rectangle, L-shapes, and U-shapes with a variety of usages.
Next, the floors are further broken down into elements called tiles floor subdivisions. Feedback-loops with clients are easily managed by sharing the proposed design options via CityEngine WebScene.
The subdivision split is performed in the same way to assure that the floor heights are in sync with the front facade. Here is an overview of the CGA-files that will be used in this tutorial:. Obviously, we only have time in this tutorial to focus on this small and abstract design. First, the facade can be decomposed into floors. We increase the cityengune of the entrance by adding a water basin and trees. Two important parameters are found here: After dropping the rule onto the shapes, the model generation is automatically started.
Select Objects with Same Rule File.
Actually, instead of placing only one, we will place nine 3×3 grid mixed-use towers with a total height of meters and check the FAR in the Reports section of the Inspector. For this purpose, we are using a fictitious example of a development area with nine building plots in the center of a city.
For the cityyengine of simplicity, we define the tutorisl framework based on the spatial context allotment, city structure, neighboring quarters etc.
Finally, we move our focus to the exterior space and add structuring elements. Edri reality, these processes are influenced by a large number of factors, such as a variety of stakeholder interests, budget, project phasing, mobility targets, capacity of infrastructure public transport, supply and wastelisted buildings, nature conservation, etc. Examining your current model, you’ll see that you can save polygons mainly on the window assets.
The Current Mouse Scheme drop-down menu lists the available schemes of other 3D apps. Download items Set up a new project First street layout Navigation and selection Model generation with rules Rule editing. The Grow Streets dialog box appears. The left-to-right rectangular selection cityenginne usually used to select tiny objects such as single Street Graph Nodes when there are many objects occupying the same space.
You’ll use textured planes instead of the complex window asset. Changes cityenginee immediately reflected in reported key figures such as FAR floor area ratio. The textures are loaded from tutoeial assets folder. A close-up view of the same model: Building attributes are typically defined at the beginning of the rule file although they can be put anywhere in the rule file.

Select Objects with Same Start Rule:. In this case, the start rule cityengne Lot. The following image shows an example of different seed values for height: The mass model is created with the extrude operation as follows:. This rule file is executed when the generation is triggered. The selection types are described in the following table:
