projections
A trimetric projection is an axonometric projection where no two axes form
equal angles with the plane of projection. Each of the three axes and the
lines parallel to them have different ratios for foreshortening. The object is
projected so that no axis forms an angle less than 90° and three different
trimetric scales must be used to lay out measurements along the axes.
Figure 6-22 is an example of a trimetric projection.
