The PVU file is the default format for exporting your 3D simulations. It is a proprietry format that requires either a web browser plug-in or standalone player to view.
The PVU file format supports full user interaction with the simulation and supports the addition of annotations which are then stored in the file.
Exporting a PVU file allows you to easily distribute the 3D simulation to your clients who may not have the full 3D-Packager software installed.
PC and Mac versions of both the browser plug-in and standalone player can be downloaded from this site.
Once you have downloaded the player, you can simply double click on the PVU file to view the simulation.
