Create a rectangular or cubical mesh box.

The base of the mesh box is drawn parallel to the XY plane of the current UCS (workplane).
You can set defaults for the number of divisions for each dimension of new mesh boxes in the Mesh Primitive Options dialog box. You can also modify these settings and the level of smoothness as you create the mesh object.
The Box option of the MESH command provides several methods for determining the size and rotation of the mesh boxes you create.
