Hello all.

Trying to figure out how to change the diameter of a datum target balloon. I can't find a setting for it anywhere and am wondering if I'm just missing it.
Thank you in advance.

I don't think that there is a setting, as I believe that the size of the datum target is defined and cannot be changed per the ASME Y14.5M standard (although I could be wrong)..

Solution that is covered in the standard:

Thanks Dan. It is strange that you can override the standard for most everything else regarding size (unverified for all, but verified for some), but not the datum target balloon.

Top one is a real Datum Target.
Bottom one is created using the SWML string:
<border type=7 size=0 padding=0><STACK divider=no><MOD-DIAM>1.25<OVER>A1</STACK></border>

That is wonderful. Thank you for that.

Is there a resource/library available to access this type of string callout to understand how to callout similar things?

There’s not really any documentation I’m aware of… You kind of just have to play around. That's what I did to create this.

I’ve attached my NoteBrowser macro that will show you the full real string content of any note. You can use the UI to format text in a certain way (fonts, numbering, fractions, borders, etc), and then use the NoteBrowser to examine the tag syntax. You can edit and tweak on the syntax in the box and hit the button to replace the text, and it will update display of the note. These tags are only for formatting stuff that’s inside the note text. If you apply a border, font size, etc to the entire note using the Property Manager, that info is not inside the note text.

Wonderful. Thank you again Josh.

Hi all. Just an FYI, but since I wanted the datum target "X" or the target balloon size to correspond to the diameter, I performed the following work around

Create a Circular split balloon
and create a datum target but get rid of the target balloon
Any of the datum target symbols can be employed.

Modifying the balloon size from the beginning would be nice for a datum target, but oh well.
