What makes a fan a fan is the blade, and being able to create a complex con-
tour is essential. To make this contour, you want to transition from one shape to
another. When you did this in sheet metal, it was referred to as a lofted fl ange .
In solid modeling, it's referred to as a lofted feature . You create these by using
