Use Offline Viewer
Depending upon your collaboration scenario, an offline viewer that allows you to review package contents may be available to you. Commonly, the offline viewer is used in situations where you do not use Windchill. In some situations, you may want to review the package content using an offline viewer prior to importing the content into your Windchill system.
The offline viewer provides a similar look to the Windchill interface and contains details about each of the objects included in the package. The offline viewer is a static and simplified view of some key object attributes and relationships. The primary intent is to provide graphical access to the content files associated with each object.
Before using the offline viewer, you should extract the contents of the package ZIP file to your local system. You can then launch the offline viewer in your browser using the index.html file at the top level of the extracted directory structure.
