I'm still trying to get familiar with the community forum layout.
My suggestion is for the NX's API, break them down to at least five individual subjects, such as...
Managed C++, VB .Net, SNAP, C#, Java
KBE - Knowledge Fusion (Designer & User Classes Design)
Similar to the programming help documents.
Maybe this exists currently and I just have not discovered it.
With regards to the GTAC Customer Forums Archive (Read-Only) - KBE section. Within the Search field, it eliminates underscores such as; "ug_datum_plane" is changed to "ug datum plane". Including the underscores in the search key phase would help narrow the search results. I tried the advance search and get the same result.
