What is an example of a 2D Engineering drawing?

A 2D engineering drawing refers to a representation of an object that includes two dimensions: length and width, without any depiction of depth. The chosen answer, which is the 3rd angle orthographic drawing, is a classic example of a 2D engineering drawing.

In a 3rd angle orthographic projection, the object is represented by two-dimensional views: typically the front, top, and side views. These views are arranged in a way that provides a clear and comprehensive understanding of the object's shape, dimensions, and features. This method is standard in engineering drawing as it allows for precise communication of an object’s details, making it easier for engineers and manufacturers to visualize and create the object.

The other types of drawings mentioned, such as exploded views and assembly drawings, typically serve a different purpose. Exploded views show the components of an assembly spread out, indicating how they fit together, and might include 3D elements. Assembly drawings provide a visual of how parts fit together but may not represent each part in a purely 2D format. Isometric drawings, on the other hand, represent three-dimensional objects in two dimensions using a specific angle of projection to show multiple sides at once, which further distances them from being classified strictly
