Plots the nodal planes and outlines the bubble which is transparent.
If *nplane* is

*0*: both nodal planes are plotted;
*0*: both nodal planes are plotted [Default];

*1*: only the first nodal plane is plotted;

*2*: only the second nodal plane is plotted.

Append **/**\ *pen* to set the pen attributes for this feature.
Default pen is as set by |-W|. [Default: 0].
Default pen is as set by |-W|.

For double couple mechanisms, the |-T| option renders the beach ball transparent
by drawing only the nodal planes and the circumference.
