Meshes are 3D objects that can simulate smooth or organic models. These meshes are represented by planar faces that enclose the object, called tessellation. Meshes were introduced in Version 2010 with additional commands added in Version 2011. The normal workflow for meshes is roughly creating the model and then smoothing it.
There are three possibilities for creating meshes: primitives, from linear objects, or by conversion. Several commands are available to edit or smooth meshes.
