Fractional Thread Callout on External Threads

HS_9187281 — Wed, 03 Sep 2025 15:25:19 GMT

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

In your hole tables, you can define the string you want to use under the parameter FASTENER_ID and call it out with the token &SCREW_SIZE, e.g.:

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.

I'm missing something. Drawing note is not pulling data from my table.

My drawing shows

My table has

Can't figure out how to get my note to show up as desired. Can you take a look at the above and point out my mistakes?

Hey @HS_9187281, I finally noticed that you are talking about external threads.

Those notes are "semi-automatically" created in the drawing mode and pull in the information from the cosmetic thread feature.

But I don't think there is a way to attach a custom parameter from the .hol file to this cosmetic thread feature.

Therefore, I don't think what you are asking about is possible.

I missed that too. I am not aware of a solution for external threads.

Thanks for looking at the issue. Never can guess what the PTC gods are thinking.

Yes, this issue has frustrated me as well. Someone has created a product suggestion for this here, though it doesn't have a whole lot of votes. Maybe we must all pay more fealty to the vengeful PTC gods?
