CityEngine offers a variety of drawing tools to create and edit Shapes and Graphs.
Shapes
Shapes can be polygons or 3D bodies that are made of multiple polygons. You can import them or draw them manually using shape drawing tools. Use push/pull tools to extrude shapes and perform 3D shape editing. In this section you will also learn how to align shapes and terrains as well as manual shape texturing.
Graphs
A graph is a structure consisting of edges and nodes. In CityEngine graphs are mainly used to layout street networks. When drawing and editing edges and nodes, dynamic shapes for the drive and pedestrian lane are created automatically.
