Hello @jaggisingh003 
Can you be more clear? Do you want to change the name of the blocks?

Do you mean Dimension objects nested inside Inserted Blocks?  If so, when you change the text content in one of them, it will change in all  Blocks of the same name.  A sample drawing would be helpful, with before and after conditions indicated.

Sample of Drawing is attached.

The block present in the Drawing is perfectly doing fine when i require it for some of the drawings but when i have to exchange the Dimension suffix "(A)" with "(B)" or "(B)" with "(C)" then it get changed for all the blocks so i always have to Explode the Block which is a tedious task so tell me a way out that how i can add suffix SD "(A)", "(B)", "(C)" to block Dimension without letting it changed in the blocks i had used earlier.

Why explode if you can use ATTSYNC ?
Add a suffix here?

The Arrow shown in picture are not attributes that  A,B,C  Dimensions. and  i want to add suffix to dimension . Eg. SD=Dimension text (A), (B), or (C)...
