Couldn't find it in solidworks 2015, the guy is using an old version of solidworks in the book i'm reading from, searched google to find out that that option has been removed since SW2010 SP2.1

Why would they do that ?

Is there any alternative or any other option that does something similar ?

btw,I can't change my name, it was supposed to have a different last name,drunk me didn't realize that how can i change it ?
