Getting a .190 hole in a part in NX7.5

[BEAEROHEAD]

In NX7.5, I put an inch helical coil NF #10-32 hole in my part. I am trying to get a dimension to read .190-32 reason being I am told that ASME standards say not to use #10-32.I can't confirm that as I cannot find the standard that says that. Wwe also use a #10-32 UNF THD HOLE. It shows up on the drawing as # 10-32. If I use UNJF I can get the dimension to be 0.190-32 (can't figure how to get rid of the leading 0) We are currently using a note not a dimension to callout the threaded holes. Any suggestions?

I don't get the whole picture, you say that "If i use UNJF I can get....to be 0.190-32" - what/ how do you use to do this ?
Manual dimensioning or "Feature Parameters" ?
Can you upload an example ( a block with a hole like the described + drawing) ?


Regards,

I think what the issue here is that while Imperial treads are generally called-out using either fractional or numbered screw sizes, the exception are the 'J' series threads, as in UNJEF, UNJF, UNJC and UNJ, which are used primarily in the aerospace industry and are called-out using their decimal equivalent dimensions, as shown below:
