Definition copy
You can create copies of objects. When copying an object, you can decide whether you wish to create a new object (a definition copy) or a new object symbol for an existing object (an occurrence copy).
It makes sense to create a definition copy for an existing object if a new object is to have similar properties to the source object.
For example, you have modeled the object Class 1 and specified its properties. You now wish to create the object Class 2, which has properties similar to Class 1. In this case, it is advisable to create a definition copy of Class 1. Object Class 2 is thus given all the properties of object Class 1, but exists independently of it.
Definition copies are assigned a name suffix. If you create a definition copy of Class 1, it is assigned the name Class1_1. You now only need to change the properties that differ from those of the object Class 1. This involves significantly less work for you than creating the object from scratch and having to enter all the properties again.
