How can i change NPT Thread angle from 3º to 1.783º on NX.

[ismail BUHUR]

i am trying to draw 1/4 - 18 NPT thread. But when i measure NPT angle , i saw it 3º. It must be 1.783º (1º47'). How can i change this degree?

Thanks in advance.

In your ugii_env.dat (name can vary based on your setup, but file, set the following variable:

# Set angle of pipe thread taper
UGII_NOMINAL_DRAWING_THREAD_TAPER_ANGLE=1.7833

NX 9, Teamcenter 10

Dave,

Thanks for your help. I am looking for I found "ugii_env.dat" file in UGII folder and opened it with notepad. But did not find.

UGII_NOMINAL_DRAWING_THREAD_TAPER_ANGLE , in this file.

1. I will add this "UGII_NOMINAL_DRAWING_THREAD_TAPER_ANGLE=1.7833" in this file or i will find this row and change older?
2. i tried this and can't save , an error appeared "access denied".

Have any suggestions about this matter?

Thx
