Oblique Sketch

Look at the picture of a cube given here.

It is drawn on a flat surface, but the picture gives us an idea as to how a cube looks like. Although the surface on which it is drawn is two-dimensional, the image looks three-dimensional. It is only a visual illusion.

To draw a solid (3D shape) on a paper, we can use various techniques. There are mainly two techniques to draw solid shapes on a paper.

In this article, you will learn to draw oblique sketch.

What is an Oblique Sketch?

In the above figure of the cube, the sides of the cube drawn are not of the same measure as they are in an original cube. Sketches of solids that give a correct idea of the shape even though the measurements are not same are called oblique sketches.

These oblique sketches are drawn on a squared sheet or on a graph paper.

Oblique Sketch Definition

In an oblique sketch, our motive is to draw a 3D shape on a paper such that the image looks like the given 3D shape. Its size might be smaller or bigger than the given 3D shape and some of its faces are not visible. Still, we can recognise it as a 3D shape. Such sketches of solids are called oblique sketches.

Oblique Sketch of a Cuboid

We can draw the oblique sketch of a cuboid with dimensions 6 units × 3 units × 4 units as explained below.

Step 1: Take a dotted sheet. Draw the front face with dimensions 6 units × 4 units.

Step 2: Draw the opposite face such that its size being the same but the sketch is to be offset from the front face.

Step 3: Join the corresponding corners (vertices).

The oblique sketch of the cuboid is drawn.

Oblique Sketch of Cube

We can draw the oblique sketch of a cube with side 3 units as explained below.

Step 1: Take a dotted sheet. Draw the front face with dimensions 3 units × 3 units.

Step 2: Draw the opposite face such that its size being the same but the sketch is to be offset from the front face.

Step 3: Join the corresponding corners (vertices).

The oblique sketch of the cube is drawn.

Example: Draw an oblique sketch of the following cuboid.
