After upgrading to NX1872 and after, customizing threaded hole standard, nx502_Threaded_Hole_Standard.xml, PMI hole callout and Drafting hole callout might not display correctly.
Solution
In NX1872, NX expects the callout string format for threaded hole to be:
Callout = ThreadSize-ThreadPitch_ThreadForm
In your nx502_Threaded_Hole_Standard.xml, if you have Callout=".125-40 UNC-2B" , to display hole callout correctly, you have to change the string from Callout=".125-40_UNC-2B" to Callout=".125-40_UNC".
