Dimetric 30°/60°
Dimetric grid with two equal axes at 30° and a third at 60°.
Axonometric is the umbrella term for parallel pictorial projections that aren't strictly isometric. Dimetric, trimetric, and oblique projections like cabinet, cavalier and planometric live under this banner - the angle you choose decides which face the eye reads first.

Dimetric grid with two equal axes at 30° and a third at 60°.
Cabinet projection - frontal plane true-shape, depth at 45°.
Cavalier oblique - front face true, depth at 45° and full scale.
Trimetric grid with three independent foreshortening ratios.
Planometric - true plan rotated 30°, verticals stay vertical.
