Hello, i would like to know, how i can insert the envelope condition behind the H7 and the circumfence.

The main problem is, that i can not use the diameter symbol in front, and the envelope in the back in the text settings in properties.
Because Catia V5 can not insert the diameter and envelope at the same time.
 

My current solution is:

Pasting the diameter symbol in the Text box and taking the envelope from the menu.
