Ballooning Drawings

Hello All, I have no dialog pop-up when I insert AutoRed in the file. Just put in the red with auto text in it.
Do I made something wrong? Adobe Reader DC the program what I have and I am not administrator on my laptop.
Could be the cause?
Thanks in advance

 

I know this is an old thread, but is there a way to edit the circle to include at least 4 characters? for example some of my dimensions require 3 digits and a suffix; 138a.

I would like to edit it on my own but I am just clueless.

 

Just wanted to say, still useful in 2024. Stamp approach mainly in Adobe Acrobat. The Combinumeral is cool, a bit weird to figure out the scheme, but not a searchable label. To change stamp size (effectively change the font size) just drag the corner. The oval stamp fits 3 characters.

 

I added them to this
C:\Users\my user\AppData\Roaming\Adobe\Acrobat\DC\Stamps

but I can't see it on the stamps that show up on my adobe, any ideas what I did wrong?
