Abstract: The axonometric drawing has the advantages of good visualization and lifelike
image. The stereoscopic effects of the axonometric drawing are relative to the position of the
geometric object. The stereoscopic effects and improve the readability of graphics can be
enhanced with the proper angle of view. According to the number of the visible planes in the
drawing, and their size and change rate in area, influence acting on the stereoscopic effects can
easily be revealed. By editing a human-computer interaction system using VisualLISP language
which embedded in AutoCAD Software and VB Software, a basis is finally set on which
axonometric projection can more efficiently express objects.

Key words: machine design, visualization, human-computer interaction, axonometric
