In the design process, you often need to replace one or more components in an assembly or assembly pattern. For example, you may need to replace one vendor's component with another.
You can replace single, multiple, or all instances of a component in an assembly. When you select a component in a pattern element, usually all occurrences of that component in the pattern are replaced. If there are multiple instances of a component in each element of an assembly pattern, not all occurrences of the component in the pattern are replaced.
The new component or all occurrences of the component are placed in the same location as the original component. Assembly relationships are retained, if possible. The origin of the replacement component is coincident with the origin of the replaced component. If the replacement part has a different shape than the original, some relationships might need to be reapplied to correctly position the component.
