Copies and/or Instances of an Object
There is a difference between a Copy of an Object and an Instance of an Object.
When copying an object, such as a Connector, Conductor, Cable, etc. you can change the attributes/definition of the object at will as it is not linked to a library object.
An Instance of an Object is a Copy of that Object in the Library that retains the Type or Defintion of the Libray Object
See Errors Associated with Types or Defintions of Objects.
