Dimetric projection involves two of the three principal axes being equally foreshortened, while the third is scaled differently. This results in two of the axes appearing at the same angle relative to the drawing plane, while the third axis is at a different angle.
Dimetric projection can offer a slightly more realistic view than isometric by varying the scaling, but it requires more complex construction since the measurements along the axes are not uniform. Despite this complexity, it provides a useful balance between realism and the ease of interpretation for certain technical illustrations.
