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 the following formats:

3D 3D GIS ArcGIS Online Customize
Wavefront OBJ Esri FileGDB
Esri Scene Layer Package SLPK Python
e-on Vue VOB Keyhole KMZ/KML
CityEngine Web Scene 3WS
Collada DAE 360 VR Experience 3VR
Autodesk FBX
Alembic ABC
Unreal UDATASMITH
Renderman RIB

Different formats are supported at different license levels. For example, the Basic license doesn't support advanced 3D formats such as FileGDB, Alembic or FBX.

See export formats for more information.

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\username\ce_workspace\models\tutorial\Parthenon.obj.
