Starting with AutoCAD 2010, the default mesh object type can be smoothed,
creased, split, and refined. Although you can continue to create the legacy
polyface and polygon mesh types, you can obtain more predictable results by
converting to the newer mesh object type.
Methods for Creating Mesh
You can create mesh objects using the following methods:
■ Create mesh primitives. Create standard shapes, such as boxes, cones,
cylinders, pyramids, spheres, wedges, and tori (MESH).
■ Create mesh from other objects. Create ruled, tabulated, revolved, or
edge-defined mesh objects, whose boundaries are interpolated from other
objects or points (RULESURF, TABSURF, REVSURF, EDGESURF).
■ Convert from other object types. Convert existing solid or surface models,
including composite models, to mesh objects (MESHSMOOTH).
You can also convert the legacy style of mesh to the new mesh object type.
■ Create custom meshes (legacy). Use 3DMESH to create polygon meshes,
usually scripted with AutoLISP routines, to create open-ended mesh. Use
PFACE to create mesh with multiple vertices defined by coordinates that
you specify. Although you can continue to create legacy polygonal and
polyface meshes, it is recommended that you convert to the enhanced
mesh object type to obtain enhanced editing capabilities.
About Tessellation
Tessellation is a collection of planar shapes that tile a mesh object. The
tessellation divisions, visible in unselected mesh objects, mark the edges of
the editable mesh faces. (To see these divisions in the Hidden or Conceptual
visual styles, VSEDGES must be set to 1.)
