Question: 1 / 400

Which type of pictorial requires representing depth at a different scale?

Trimetric pictorial

Isometric pictorial

Oblique pictorial

In oblique pictorial drawings, depth is represented at a different scale than the height and width. This technique involves projecting the object's depth at an angle, typically at 45 degrees, to create a three-dimensional effect. Unlike isometric pictorials where all three axes are drawn to the same scale, or trimetric and auxiliary pictorials that also maintain consistent scaling for certain dimensions, oblique drawings specifically distort the depth dimension to enhance the visual representation of the object. This allows for a more realistic depiction of complex shapes while providing clarity on the frontal view without distorting height and width, making oblique pictorials particularly useful for conveying certain design aspects effectively.
