Orthographic projections, ContinuedTrimetricprojectionsA trimetric projection is an axonometric projection where no two axes formequal angles with the plane of projection. Each of the three axes and thelines parallel to them have different ratios for foreshortening. The object isprojected so that no axis forms an angle less than 90° and three differenttrimetric scales must be used to lay out measurements along the axes.Figure 6-22 is an example of a trimetric projection.Figure 6-22.—A trimetric projection.6-27Continued on next page
