Hello,

You can remove commands or even whole groups from the NOV Diagram ribbon either programmatically or through the Visual Studio designer. Adding items to the ribbon can only be done programmatically. Please take a look at the following online documentation topic for more information and code samples:

I am evaluating NOV Diagram.  I there a way that I can customize the ribbon menu.  I would like to add my own section next to the drawing tools and there are several section that I would like to hide.

Thanks,
