A mesh can be open or closed. If the start and end edges of the mesh do not
touch, a mesh is open in a given direction, as shown in the following
illustrations.
Create a Rectangular Mesh
With the 3DMESH command, you can create polygon meshes that are open
in both the M and N directions (like the X and Y axes of an XY plane). In most
cases, you can use 3DMESH in conjunction with scripts or AutoLISP routines
when you know the mesh points.
As you create the mesh, you specify the size of the mesh in the M and N
directions. The total number of vertices you specify for the mesh is equal to
the M value times the N value.
