What is oblique projections?

Oblique projection is a type of three-dimensional projection used in technical drawing, architecture, and engineering. In an oblique projection, the object being represented is projected onto a two-dimensional surface at a 45-degree angle to its base. This creates a distorted image, where the sides of the object look longer than the front and back.

There are two types of oblique projections: cavalier projection and cabinet projection. In cavalier projection, the object is drawn with full depth, meaning that each axis is projected to the same length on the drawing surface. Cabinet projection, on the other hand, presents a more accurate representation by projecting each of the axes at a different length, creating a more natural-looking image.

Oblique projections are often used in technical drawing because they are easy to construct and provide a quick overview of the object being represented. However, they can be less accurate than other types of projections, such as isometric or perspective projections.
