What are Street Networks
Street networks represent the arteries of a city and describe therefore its formal shape and structure by defining or affecting enclosed blocks, building lots and spaces in between.
The CityEngine contains a powerful tool set to design streets manually or to let street networks grow with a procedural street generator enabling the user to create a variety of realistic looking street configurations.
Additionally, street networks can be exported from 3rd party applications like AutoCAD and imported as a street layer into the CityEngine. Various file formats are supported, including ".shp", ".osm" and ".dxf".
BlocksStreet layers consist of the network (edges and nodes) and the blocks:
The visibility of the sub-layers Network and Blocks can be toggled by clicking on the eye icon on the left side of the labels.For each loop in the graph network, a block is created. A block can reference a set of attributes and controls its subdivision into lots, see Creation of Shapes from Graph Networks.
Blocks are automatically updated and can't be deleted. However, shape (lot) creation can be disabled, see Block Parameters
Blocks can be selected by clicking on the dashed line.
