swept loft

hello,

     I am using Solidworks Office Premium 2009 x64 with SP5.1. I am trying to model a trough conveyor belt. the belt transitions through 2 different profiles as it travels around it's oval like path. someone told me there is a feature in Solidworks called a Swept Loft that would handle this but I was unable to locate this feature. can someone tell me where i might find it?

Thank you
