question about npt

Hey,


I have a question about adding NPT on a bush.
I have a bush which on the one side should be provided with 3 "NPT (male) and on the other side with 2" NPT (Female)
Now I do not know what I need to check on "insert cosmetic thread"
solidworks drawing the lines of the wire straight instead of diagonally., as NPT should be.


I hope you can help me.
