After much scrubbing the internet i was unable to find a good way to edit KBE / .dfa files without having to install Visual Studio. As a software engineer i happen to enjoy using notepad++ as a lightweight editor with syntax highlighting. So i decided to go ahead and create a language file that can be used with NX Knowledge Fusion.
Download the Language File hereDOWNLOAD
Extract the kbe.xml file
Select Import and Choose the kbe.xml file
Afterwards you should be able to select KBE as a language in the Bottom of the language menu.
