The Subdivision Surface tools offer a modeling technique where you can begin modeling with a basic shape having a subdivided surface. The subdivided surface is a curved limit surface represented by a coarser polygonal control cage. After creating the basic shape, you can use the various tools in the Sub-D tab to further subdivide the surfaces and add detail to form more complicated shapes.

You can also convert an existing faceted or solid model to a subdivided surface and perform editing operations to add in details as needed.

The video illustrates how you can use this feature.

For more understanding and how to use this feature with product design examples you can refer this Sub D Modeling in Ansys Discovery course.
