Introduction to the Windchill Viewable Compression Utilities (pvsoptimize)
The Arbortext Publishing Engine (PE) publishes Dynamic Documents created using the Arbortext Editor as part of the Windchill based Arbortext Content Manager (ACM) and Service Information Manager (SIM) solutions. The Arbortext Editor has the ability to display a Graphic Dynamic Document (GDD) in a publication for illustration purposes. The GDD is essentially a copy of an existing WVS representation containing Creo View files that were generated from CAD data using an adapter. An Arbortext GDD can be very large in size, since it contains rich viewable data intended for an engineering oriented consumer base. This information is not necessarily needed when the viewable information is intended for downstream publications. Using pvsoptimize, you have the ability to create lightweight GDDs by removing the engineering oriented information (also called intellectual property).
The existing Creo View technology offers tools to perform post-processing of viewable data via the pvsoptimize utility. This utility can be configured to convert existing heavyweight Creo View data to lightweight data from the command line.
An Arbortext GDD having a PVZ as its primary content is created during a Visualization process called “Post-Publishing” – which can be configured to execute immediately after a Publish Job completes or manually invoked on a specific representation through the WVS Publish Rules XML file configuration. Refer to the ACM or SIM . The WVS Post-publish Delegate copies an existing representation’s Creo View data, creates a new GDD object, and stores the copied PV data as content on this new GDD.
The Viewable Compression Utilities are used similarly to the server-side Thumbnail Generator (pvsthumb). The pvsoptimize command is deployed on the Windchill server using the PTC Solutions Installer (similarly to the Thumbnail Generator), and can be executed from the command line. In addition, a default Recipe Editor file adds configuration flexibility.
The pvsoptimize utility can be used to convert PVS, OL, and PVZ files in one of two ways:
• The pvsoptimize utility can be executed on the command line in a command shell. This method is described in Command Line Execution of PVS Optimize.
• The pvsoptimize utility can be executed in the background, by a system call from the Windchill server, to convert files as needed, without direct user intervention. The command line syntax used for the system call is configured by a Windchill Visualization Services property viewable.compression.nativecmd. See the Windchill Visualization Services Administrator's Guide (Guide de l'administrateur de Windchill Visualization Services) for more details.

Once a command-line conversion is completed, the files are output to the directory you specified, where they can be accessed and viewed using the Creo View client. In addition, the Recipe Editor provides the administrator with complete control of the PVSOPTIMIZE settings. See Introduction to Recipe Editing for Converting CAD Data for an overview of the recipe concept.
