Abstract: The application of the projection transformation method to establish a
mathematical solution model of Axonometric Projection is adopted to propose a general telescopic
coefficient method to realize the real size of axonometric Projection conversely Then,
three-dimensional entity modeling is conducted to achieve original design from human brain
against computer constraints. Finally, the 2D drawing is produced for engineering processing. All
these processes are done by computer, making it in more accordance with the essence that design
starts from 3D Image.

Key words: axonometric projection, model reconstruction, projection transformation;
