MESH (Command)

Creates a 3D mesh primitive object such as a box, cone, cylinder, pyramid, sphere, wedge, or torus.

Find

The basic mesh forms, known as mesh primitives, are the equivalent of the primitive forms for 3D solids.

You can reshape mesh objects by smoothing, creasing, refining, and splitting faces. You can also drag edges, faces, and vertices to mold the overall form.

Note: By default, new mesh primitives are created with no smoothness. To change the default smoothness, enter MESH at the Command prompt. Then specify the Settings option before you specify the type of mesh primitive you want to create.

The following prompts are displayed.
