When you select part instances to copy, the corresponding part is also
  selected by default; you can deselect the part if it already exists. You cannot
  copy other individual objects, such as the assembly, loads, or steps; however,
  you can achieve a similar effect by copying the entire model to a new model and
  editing the objects in the new model. For more information, see 
  Manipulating models within a model database.
  Dependent objects are not copied automatically when you copy an object between
  models. For example, if you copy a section, the associated material is not
  copied along with the section; you must copy the material in a separate copy
  operation. 
 
If you are copying a part and the assembly context of the model to which you
  are copying the object is displayed in the viewport, the assembly will be
  regenerated only if an instance of the part being copied exists in the assembly
  of the model to which you are copying the object. 
If you are copying a model instance and the target model contains an
  instance with the same name, the instance in the target model is first deleted
  and a new instance is created by copying the model instance from the source
  model. Any features, such as sets and surfaces, associated with the deleted
  instance are invalidated.
 
 
 
   
	 From the main menu bar, select
		. 
	  
	 
The Copy Objects dialog box appears. 
	 
 
   
 
   
	 From the dialog box, select the model to copy objects from. 
	  
  
 
 
   
	 Use the following techniques to specify the objects to copy from the
		selected model: 
	  
	 
 
		
 
		  -  
			 
Click the arrow next to the desired object category. From the list
				of objects that appears, toggle the names of the objects of your choice. An
				object category is unavailable if it contains no objects. 
			 
 
		   
 
		  -  
			 
Toggle the desired object category. This action selects or
				deselects all objects within that category. 
			 
 
		   
 
		
 
	  
	 The check box next to an object category displays a black check mark
		on a white background when all objects within that category are selected. The
		check box displays a dark gray check mark on a light gray background if only
		some of the objects within that category are selected. You must select at least
		one object or object category to copy. 
	 
 
   
 
   
	 From the bottom of the Copy Objects dialog box,
		select the model to copy the selected objects to. 
	  
  
 
 
   
	 Click OK to copy the selected objects and to
		close the Copy Objects dialog box. 
	  
	 
Abaqus/CAE
		copies the selected objects. If an object with the same name already exists in
		the model to which you are copying the object, 
		Abaqus/CAE
		asks for confirmation that you want to overwrite the existing object. Click
		Yes to All to overwrite all existing objects with the
		same name as the objects you are copying.
