Surfaces

Surface modeling is more sophisticated than wireframe modeling in
that it defines not only the edges of a 3D object, but also its surfaces.
The AutoCAD surface modeler defines faceted surfaces using a polygonal
mesh. Because the faces of the mesh are planar, the mesh can
only approximate curved surfaces. With Mechanical Desktop, you can
create true curved surfaces. To differentiate these two types of surfaces,
AutoCAD calls faceted surfaces, meshes.
