Fractional Thread Callout on External Threads

Currently using Creo 11. I've found some posts, but no solutions. Is there a way to automatically show external cosmetic threads in their typical format such as 1/4"-20 instead of 0.250-20? There was a post from years ago about editing the .hol table, but this method doesn't work as somewhere along the line PTC changed the format of the hole table. Now in the table, there is only "BASIC_DIA". If you edit the table to say 1/4 or "1/4", a value of 0 shows up in the hole note.

You can create your own parameters in the hol file. For instance:

DEFAULT_CALLOUT_FORMAT_DATA
HOLE_TYPE THREAD DRILLED_DEPTH THREAD_DEPTH CSINK CBORE EXIT_CSINK CALLOUT_FORMAT
TAPPED YES NA NA NO NO NO {0:&HOLE_INSTANCE_COUNT&HOLE_INSTANCE_X_SYMBOL&HOLE_INSTANCE_SPACE} &MY_PARAM_HERE

and then in the hol file off to the right you have:

BOTCSINKANGLE MY_PARAM_HERE
60 2-56
60 4-40
60 6-32
60 8-32
60 10-24
60 1/4-20

When you show annotations for the feature I'm guessing this won't show up. Wouldn't you have to create a manual note?

No. No manual note. You define the hole note in the .hol file. You can make the hole note say anything you want and then it shows up as the hole note annotation.
