You can create multiple, independent instances of components in an assembly. You must modify, replace, or delete the copied components one at a time.

When you copy a component, its placement is based on the coordinate system of the assembly. The coordinate system is used as reference for translating or rotating components. For example, for a rotational copy of a component, you can rotate it around the coordinate system of the assembly. In general, copied members use the same dimensioning references as the source component (leader). Rotate the component (leader and all members) around the coordinate system of the assembly first, and then translate (move) it.
