In CFX-Pre, the 3D Viewer is visible whenever a partial or complete case is loaded. After importing a mesh into CFX-Pre, you can see a visual representation of the geometry in the 3D Viewer. You can create various other objects that can be viewed in the 3D Viewer; for details, see CFX-Pre Insert Menu. The visibility of each object can be turned on and off using the check boxes in the tree view; for details, see Object Visibility.

Descriptions of the various viewing modes and 3D Viewer commands, including toolbars, shortcut menus, and hotkeys, are given in 3D Viewer Modes and Commands.

You can switch between four adjustable "views" that each remember the camera angle and state of visibility of all objects.

The 3D Viewer can display multiple viewports at a time. The viewport arrangement is controlled from the viewer toolbar.
