You can use the Remove Break Line Inheritance command to remove the association between break lines created with the Inherit Break Lines command.
Right-click the drawing view.
Select the Remove Break Line Inheritance command from the shortcut menu.
The break lines still exist on the drawing view, but they are not associative to the break lines in the source view.
Tip:
Another way to remove the relationship is to select the Delete Alignment command from the shortcut menu, and then click the alignment line between the drawing views.
Once the relationship is removed, you can delete the break lines using the Deleted key.
