You create surface models using some of the same tools that you use for solid
models: sweeping, lofting, extruding, and revolving. You can also create
surfaces by blending, patching, offsetting, filleting, and extending other
surfaces.
Mesh Modeling
A mesh model consists of vertices, edges, and faces that use polygonal
representation (including triangles and quads) to define a 3D shape.
Unlike solid models, mesh has no mass properties. However, as with 3D solids,
you can create primitive mesh forms such as boxes, cones, and pyramids,
starting in AutoCAD 2010. You can modify mesh models in ways that are not
available for 3D solids or surfaces. For example you can apply creases, splits,
and increasing levels of smoothness. You can drag mesh subobjects (faces,
edges, and vertices) to deform the object. To achieve more granular results,
you can refine the mesh in specific areas before modifying it.
