Subdivision Meshes

Mesh modeling enables to approximate a smooth surface using a mesh of faces called

subdivisions

Tessellation lines represent the visual boundaries of each subdivision

Each subdivision has one face, no <> 4 edges, and a corresponding number of vertices

Each subdivision face, edge, or vertex can be edited independently by moving, rotating, or scaling it with the 3D-Gizmo

The black lines on the model are called tessellation lines and visually represent the boundaries of each subdivision
