Thumbnail Generation with VCS
Visualization Content Service (VCS) can generate 2D and 3D Thumbnails that are displayed on Thumbnail Navigator or Details page.
With VCS, thumbnail generation is enabled with the following properties on Windchill:
• wvs.vcs.supportedworkers = THUMBNAIL
• enable.thumbnail = true
If thumbnail generation is enabled with VCS, it generates thumbnails in the following scenarios:
• CAD worker or non-CAD Worker published jobs
• Server-generated representations
• Scheduler-based thumbnail generation
The Windchill administrator do not need to configure a dedicated thumbnail worker or set any property to generate thumbnails. Once Windchill is configured to generate thumbnails with VCS, properties like thumbnail.usecadagent are ignored. Creo View Adapter for Windchill need not be installed on Windchill for server-side thumbnail generation. However, there can be a scenario where it may still be required for Viewable Compression Utilities.
The thumbnail generation process is as follows:
1. Windchill triggers the publish job.
2. Windchill validates that the publishing job has generated the thumbnail.
3. Windchill updates primary parent representation and uploads content.
4. If the thumbnail is not generated, then Windchill creates a new thumbnail job. The WVS job monitor shows the log as Thumbnails unavailable with representation, creating Thumbnail Job. Along with this message WVS also writes the new thumbnail job’s id, which can be utilized for search for respective thumbnail job in the job monitor.
5. The thumbnail is added to the VCS thumbnail queues with same priority as that of parent job.
 | • While generating thumbnail, Windchill downloads representation content. The number of files to be downloaded is controlled with the property thumbnail.filelimit, with default limit set to 800. Refer Windchill Visualization Service Properties for more information. • For documents which are restricted for thumbnail generation via publish and thumbnail control, the thumbnail job is not triggered. Refer About Publish and Thumbnail Control for more information. • Windchill skips thumbnail generation request to VCS for the representations with no viewable (empty representation). The job log displays the message Thumbnail Generation Skipped - The representation contains no content for generating thumbnails. |
