You can separate the individual objects that make up a symbol only if all pins belonging to the symbol are free from connections.
Perform the following operations:
Select the symbol to divide.
-
Choose the command Schematic » Symbol » Split or click the
button in the toolbar.
The Split command deletes the grouping applied to objects. The symbol is deleted and the individual objects that make it up are added to the document. The appearance of objects does not change when they are separated. The status line, however, indicates that multiple objects are selected. If the symbol contains groups of objects, the Split command allows you to separate one level at a time.
 Warning: |
|---|
When you split a symbol, the status attributes (visibility, protection, etc.), name, description, and any other internal attributes assigned to the symbol are lost. |
