Creo View Installation and Configuration Guide > Hierarchical Visual Navigation
Hierarchical Visual Navigation
You can rapidly load the approximate 3D model graphics for very large Creo View structures by loading 3D thumbnail image (PVT) files of the structures that were previously created. Once the thumbnail is loaded you can switch to the full 3D model view (OL file). You can also revert from the full 3D model view back to the 3D thumbnail image.
This functionality is available only under the following conditions:
3D thumbnail images have been generated for sub-level assemblies. This requires configuration of the CAD worker or the server-side Thumbnail Generator to create them. See Enabling Hierarchical Visual Navigation.
options are configured to download and view thumbnails. See About Thumbnails.
