The purpose of a series of study on construction of perspective drawing by projective mapping is the investigation of the way that even an amateur can construct perspective drawings of a solid by projective mapping of a pair its orthogonal projections or generally its parallel peojections.<BR>But when a pair of parallel projections and a position of a point of sight are given, perspective drawings constructed by projecting those figures from two points are not necessarily practical.<BR>This paper represents the theory and practice of the drawing method of transformation of perspective drawing given, which analyses it into two lines and reconstructs it by projective transformation on the basis of a proper line and four points.
