Nevron Open Vision (NOV) comes with more than 350 predefined shape libraries (NLB files), which you can load and use in your applications. They are placed in the "Resources\ShapeLibraries" sub folder of your NOV installation. Take a look at the "Diagram -> Shape Libraries" NOV examples for code examples.

To browse the predefined libraries run the NOV Examples and open the Diagram > Demo Apps and Diagrams > Diagram Designer example. Then click the button with a blue book at the top left corner of the library browser and select "Library Gallery..." from the drop down menu that opens.

When developing a desktop application (a WinForms, a WPF or a Xamarin.Mac application), shape libraries can be distributed either as files in a "Resources\ShapeLibraries" sub folder of the application or as embedded resources in the application. For web (Blazor WebAssembly) applications, we recommend distributing shape libraries as embedded resources.

For more information on how to load and use shape libraries take a look at the "Loading and Using Libraries" section of the Libraries topic.
