What the principles of oblique projection?

Oblique projection is a type of graphical projection used to represent three-dimensional objects in two dimensions. The key principles include projecting the object onto a plane using parallel lines that are not perpendicular to the projection plane. Typically, the front face of the object is shown in its true shape and size, while the depth is represented at an angle (often 30 or 45 degrees) to create a sense of depth. This method allows for a clear depiction of the object's dimensions and features without the distortion that can occur in perspective drawings.
