• 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.
