About Manipulating Symbol Instances
Just as you might modify the value or location of drawing dimensions, you can modify symbol instances in your drawings. You can alter any of the symbol attributes as necessary.
You can apply any changes to the symbols individually or you can update all instances throughout the entire drawing by redefining the symbol definition.
The following actions are typically applied to individual symbol instances:
Adjust the symbol height
Change the angle at which the symbol is displayed
Reposition the origin of the symbol
Modify the symbol group attributes
Edit the variable text values
Convert the instance to draft entities
Reattach instances and add new leader lines
To ensure that the changes are available for another drawing session, you should modify and save the symbol definition within the symbol directory.
