Guidelines for Restructuring Components
Keep the following guidelines in mind when you restructure an assembly component:
When you restructure an assembly component you cannot restructure the following components:
Pattern members
A component that has multiple occurrences
Excluded or substituted components
When you restructure an assembly, component placement constraints and references can change:
When you restructure a component assembled with a Default placement constraint, the constraint automatically changes to Fixed.
When you restructure the first component of an assembly, it is restructured in the Model Tree, but the location in the graphics window remains unchanged.
When the restructured component and the target subassembly are members of the same level assembly, you must move the children of the restructured component as well.
The reference path of the restructured component is updated to minimize external references.
 
When you restructure a component of a simplified representation, you can retrieve parent components on-demand in order to restructure the children successfully.
You cannot restructure components of an external simplified representation.
