Question

A cube with an edge $4$ cm long. Draw its oblique sketch and isometric sketch.

Answer 1

(i) Oblique sketch:

Let us draw an oblique sketch of a cube dimensions $4\times 4\times 4$ cubic cm.

Step $\mathbf{1}$: Draw the front square face on a squared lines paper by taking $4$ squares on both sides.

Step $\mathbf{2}$: Draw another square face of same size, somewhat off set from step $1$.

Step $\mathbf{3}$: Join the corresponding corners.

Step $\mathbf{4}$: Redraw the sketch using dashed line segments and solid line segments (use dashed line segments for edges that cannot seen).

(ii) Isometric sketch:

To draw an isometric sketch of a cuboid of dimensions $2$ cm by $2$ cm by $2$ cm, follow the steps in the figures given below:

Step $\mathbf{1}$: Draw a rectangle of dimension $2$ cm by $2$ cm to show the front face.

Step $\mathbf{2}$: Draw four oblique line segments from the four corners of length $2$ cm.

Step $\mathbf{3}$: Draw the lateral face by connecting vertices.

Which is the required isometric sketch.
