Abstract: Based on the drawing method of structure of a part after a cutting pane in cutaway
view in mechanical drawing standard, the specific definition of “other structures after the cutting
plane” and “Sectioning structure and its related parts” is established. If the axis of physique which
it belongs to is intersection of two section cutting plane when some structures have not been split
cut, it is the other structures after the cutting plane, and it should be projected according to the
original position. Otherwise, it is the sectioning structure and its related parts, and should be
rotated to a new location with his structure. This paper also describes with proven that it should
not delete “the other structures behind a cutting plane are projected according to the original
location” in mechanical drawing standard.

Key words: cutaway view, aligned section, structure, drawing method
