projections
A dimetric projection is an axonometric projection where two of an objects
axes make equal angles with the plane of projection and the third angle is
larger or smaller than the other two. You use one scale for the two equal
axes and change scale to foreshorten the third axis in a different ratio. Do
not confuse the angles between the projection of the axes and the angle the
axes make with the plane of projection. Dimetric projections are used less
often than isometric projections.
Figure 6-21 shows an example of dimetric projections.
