CityEngine offers a variety of drawing tools to create and edit shapes and graphs.
Shapes
Shapes can be polygons or 3D models that are made of multiple polygons. You can import them or draw them manually using shape drawing tools. Use the Push Pull tool to extrude shapes and guides to perform 3D shape editing with precision. 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 lay out street networks. When drawing and editing edges and nodes, dynamic shapes for the drive and pedestrian lanes are created automatically.
