(3) Hierarchical Arrangement of Drawings
Drawings are arranged in the following order: Parent drawing, child drawings, grandchild drawings. A parent
drawing cannot call a child drawing of a different type, and a child drawing cannot call a grandchild drawing of a
different type. A parent drawing also cannot directly call a grandchild drawing. A child drawing is called from a
parent drawing, and a grandchild drawing is called from that child drawing. This is called the hierarchical
arrangement of drawings.
Each processing program is prepared with the parent drawing, child drawing, grandchild drawing hierarchy, as
shown below.
