[ c ] Hierarchical Structure of Drawings
Each processing program is made up of parent drawings, child drawings, and grandchild drawings. Parent drawings
cannot call child drawings from a different type of drawing and child drawings cannot call grandchild drawings from a
different type of drawing. Also, parent drawings cannot directly call grandchild drawings. Child drawings are always
called from parent drawings and grandchild drawings are always called from child drawings. This is the hierarchical
structure of drawings.
As shown in the following figure, each processing program is created from a hierarchy of parent, child, and grandchild
drawings.
