oblique drawing?

An oblique drawing is a type of 3D (three-dimensional) sketch or projection used to represent an object where the front view is drawn true to shape and size, while the side or top views are drawn at an angle — usually 30°, 45°, or 60° — to give the illusion of depth.

Key Features of an Oblique Drawing

Front face → drawn exactly as it appears (true shape and scale).

Depth lines → drawn at an angle (commonly 45°) and usually reduced to half-scale for realism.

Parallel projection → all parallel lines remain parallel (they don’t converge like in perspective drawing).

Types of Oblique Drawings

Cavalier Oblique → Depth is drawn at full scale (makes the object look stretched).

Cabinet Oblique → Depth is drawn at half scale (looks more natural and realistic).

Uses

Engineering and technical drawing.

Architecture and product design.

To give a simple 3D view without complex perspective calculations.

Example

If you draw a cube:

The front square is normal.

The sides are drawn at 45° to the horizontal, with lines about half the real depth (in cabinet style).

Oblique drawing is a simple way to create a three-dimensional image of a 3D object on a 2D surface, where the front face of the object is shown in true shape and size. The depth is shown with receding lines drawn at an angle (often \(45^{\circ }\)) to the horizontal, which are kept parallel to each other. This makes it easy to draw and is useful for showing the most detailed face of an object, especially one with circles or curves.
