Quick Start: Model Export

CityEngine can export graphs (street networks), shapes (such as lots or street shapes), and models (such as buildings). This page describes a step-by-step workflow for how to export the models (i.e. building- and street-geometry) into the Wavefront OBJ format.

CityEngine can export to a number of other formats. Here is an overview (see the manual for details):

Exporting Models to Wavefront OBJ Format

  1. Open a scene (e.g. one of the tutorial scenes) and select some shapes in the Shape Layers or by Right-Left-Drag-LMB. The highlighted parts in the following screenshot show that we have selected two shapes with the same rule file and the same start rule. For the left shape, we have already generated a model.
  2. Open the batch export wizard with File → Export.... You will be presented with the first of three wizard pages for the batch export of models. Select the entry
    CityEngine → Export Models of Selected Shapes (all models are generated) and hit next.

  4. The third page lets you choose amongst a variety of format-specific options. The most important ones are the export location and the file base name (highlighted). Please refer to the Export Option Reference for a description of the individual options.

  5. Hit Finish to start the batch export.
  6. The obj file, textures and an export log are written to the target location, in this case C:\Users\user_name\Documents\models\building.obj.
