I created a symbol with a whole section (but it was a mistake).
I only want to have a container from this section as a symbol.
My problem is : I can delete the symbol without deleting my original work.
Moreover, I can’t create the right symbol I want because I can’t create a symbol from a symbol.
It’s easy, just right click the symbol while having it selected and go down to the bottom. You should see an unlink symbol option. Or you could select the symbol and press : Ctrl + Shift + A
