OpenDRIVE Export Preview Tool

OpenDRIVE Export Preview Tool button

The OpenDRIVE® Export Preview Tool is used to visualize and validate an OpenDRIVE export of the current scene and to load external OpenDRIVE files. Upon entering the tool, the OpenDRIVE export dialog box is displayed. After clicking Export, the current scene is exported to a temporary OpenDRIVE file, which is then loaded, validated, and displayed.

Validations are run both before export and after loading the exported data. This validation output is printed to the Output Panel. Most validation errors or warnings include hyperlinks in the message. Click on a link to focus on the object or issue.

To avoid visual clutter, click the Show Background Scene button to toggle display of the scene meshes. The Show OpenDRIVE Lane Markings button toggles display of the OpenDRIVE lane marking attributes, which are displayed only when a road curve is selected.

You can also use the OpenDRIVE Export Preview Tool to validate and display existing OpenDRIVE files. This can be useful for validating files from other sources or previewing an OpenDRIVE file prior to import.
