There are example applications and graphics libraries that are included with PanelBuilder32. These include quite a lot of graphic objects for pumps, motors, pushbuttons, etc.
The pertinent default directories are:
C:\Program Files\Allen-Bradley\PanelBulder32\Demos\PanelView
C:\Program Files\Allen-Bradley\PanelBulder32\Demos\Bitmap Library
I think the Bitmap Library is installed by default but you have to specify installation of the demo applications during installation of PanelBuilder32.
