While in assembly and looking at my feature manager tree I have a particular part's name or the information that SW is giving me about that part that is confusing me. As I see it in the essentials book I am borrowing, the component has a number in brackets <#> after its name that indicates the instance. 1 for one of those in the assembly. 2 for two of those in the assembly and so on. If your instance number is two, shouldn't that mean you have two of those components assembled into the assembly? I have only one of these parts assembled in and am confused as to why SW is telling me 2 for the instance number.
