3. Go to PIPING_NETWORK_SYSTEM class and switch to properties tab and locate the NOMINAL_PRESSURE property.
4. Right click on the property and select Remove Units option.
   
   
5. Once the units are removed from this property you won't see the Units tab in the lower section for that particular property.
6. Save the changes in schema.

2. Select the Major Pipeline tool from Piping Task.
3. In the placement dialog, key-in any value in Nominal Pressure property, you will see that Units are not populated.
