Oblique Drawing: An Overview

An oblique drawing is a type of perspective drawing commonly used in technical and architectural illustration. It is a two-dimensional representation that provides a sense of depth and dimension, giving the viewer a more accurate understanding of the object or structure being depicted.

In an oblique drawing, the object is angled and slightly skewed in relation to the viewer, creating a three-dimensional appearance. This technique allows for a clearer presentation of the object’s features and proportions, making it easier to visualize and understand complex designs.

The Types of Oblique Drawing

There are two primary types of oblique drawings: cavalier and cabinet. These variations differ in the way the object is scaled and oriented, resulting in slightly different visual effects.

Cavalier Oblique Drawing

In a cavalier oblique drawing, also known as a “full-scale” oblique drawing, the object is displayed with its true proportions. This means that all dimensions, both horizontal and vertical, are shown at full size. However, the depth dimension is exaggerated, typically displayed at a 45-degree angle from the viewer. As a result, a cavalier oblique drawing can make an object appear distorted, but it allows for a clear representation of the object’s features and dimensions.

Cabinet Oblique Drawing

In contrast, a cabinet oblique drawing also includes a true representation of the object’s width and height, but it reduces the depth dimension by half. This means that the depth lines are shown at a 30-degree angle from the viewer, resulting in a less exaggerated sense of depth. Cabinet oblique drawings often appear more natural and realistic compared to cavalier oblique drawings.

The Benefits and Applications of Oblique Drawing

Oblique drawing offers several benefits and is widely used in various applications, particularly in technical and architectural fields. Some of the key advantages of oblique drawing include:

Improved Visualization

Oblique drawings provide a clearer visualization of objects or structures compared to traditional orthogonal (straight-on) views. The skewed perspective enhances the understanding of dimensions, features, and spatial relationships.

Easier Comprehension of Complex Designs

For intricate or complicated designs, oblique drawing is invaluable. It allows designers, architects, engineers, and technical illustrators to communicate complex concepts in a more accessible manner. By incorporating oblique drawings into presentations or technical documents, stakeholders can better understand the final product or structure.

Enhanced Design and Modification Process

Oblique drawings enable designers to examine their creations from different angles and perspectives. This facilitates the identification of design flaws, inconsistencies, or areas that require modification. With this insight, designers can refine their ideas and improve the overall design before moving forward with the physical construction.

Technical Illustration

Oblique drawings find extensive usage in technical illustration, such as instruction manuals or assembly guides. By providing clear and accurate depictions of parts and assemblies, these drawings aid in the comprehension and efficient assembly of complex products.

The Creation of Oblique Drawings

Oblique drawings can be created using both traditional and digital tools. Traditionally, artists and illustrators would use rulers, protractors, and drafting machines to achieve precise angles and proportions. Today, computer-aided design (CAD) software has become the preferred method for creating oblique drawings, offering greater flexibility, accuracy, and the ability to easily make changes.

When creating an oblique drawing, the artist must determine the angle and scale of the object, decide on the type of oblique drawing (cavalier or cabinet), and carefully sketch the lines with the appropriate measurements. The selection of colors or shading techniques can further enhance the visual impact and realism of the drawing.


Oblique drawing is a valuable technique in technical and architectural illustration, providing an effective means to communicate complex designs and concepts. Whether in the form of cavalier or cabinet oblique drawings, this approach offers improved visualization, easier comprehension, and enhanced design capabilities. By utilizing both traditional and digital tools, artists and designers can create compelling oblique drawings that bring their ideas to life.
