Even if you select the "Diagramming" creation template in the new creation dialog and perform OK, Diagramming creation environment is not entered and Gateway environment is entered.
Reproduced Steps:
1. File > New > Diagramming tab > select any template > OK
Result:
The behavior is due to NX problem and has been fixed in NX 2206.4020.
NotesThe problem occurs only in NX 2206 Series.
Note that this only happens if you don't have the NX Diagramming [NX30900] license, i.e. you don't have the "nx_diagramming" feature. The cause is that the algorithm that grabs the token license is not working.
Reference: When it works normally, the "Run Navigator" will open in the resource bar as shown below.
