NAME
     AddDrawobj - add line, rectangle or circle

SYNOPSIS
     AddDrawobj ( line | rect | circle ) ( 2D | 3D )

DESCRIPTION
     Add a line, rectangle or circle for annotation.
     The first argument selects the type of drawing object.

     If the second argument is 2D, the object is placed
     at a default location and can be moved to the desired
     place. It will always keep its screen position and is
     not related to any atoms.

     If the second argument is 3D, a label is added for
     each molecule that has selected atoms. The initial
     position in space is calculated as the average of the
     coordinates of all selected atoms of the molecule. The
     positon relative to these atoms can be changed with
     the mouse or with the MoveDrawobj command.

     The created primitives have the property "drawobj".
