SPHERE allows you to create a point mesh that approximates 
a sphere. Create the mesh in one of the following ways:

- specify the center and radius of the sphere, as well as
  the number of latitude and longitude lines.

- specify the center and diameter of the sphere, as well 
  as the number of latitude and longitude lines.

Select a method for creating the mesh by choosing from the
following options:


CTR+RAD - to create a mesh given the center and radius of
the sphere, as well as the number of longitude and 
latitude lines in the sphere.

Locate the center of the sphere using a Position Menu
option.

Enter the radius of the sphere as a number greater than 
0.0.

Enter the number of longitude and latitude lines.

CTR+DIA - to create a mesh given the center and diameter 
of the sphere, as well as the number of longitude and 
latitude lines in the sphere.

Locate the center of the sphere using a Position Menu
option.

Enter the diameter of the sphere as a number greater than
0.0.

Enter the number of longitude and latitude lines.

Indicate whether or not you want to group the entities.
Choose NO to continue without grouping. Choose YES to 
create a group, and enter a group name.

The mesh is created.
