Oblique projection represents depth through the use of slanting lines. This technique involves drawing the object in such a way that one face is shown in true size and shape, while depth is added by projecting the other dimensions at an angle, typically 45 degrees. This approach allows the viewer to perceive three dimensions on a two-dimensional surface, providing a clearer visualization of the object's form and structure. It contrasts with methods that rely solely on horizontal or vertical lines, which would not effectively convey depth or three-dimensionality. Dotted lines are typically used in technical drawings to represent hidden edges or features rather than displaying depth.
