Exercise 15.2

1. Use isometric dot paper and make an isometric sketch for each one of the

given shapes:

(i)


A cuboid picture


Ans: Isometric Sketching is a representation of an object in which all the three-dimensions are drawn at the full scale. It looks like an isometric projection. In this case, all the lines parallel to its major axes are measurable.


Isometric sketch of cuboid


(ii)


Three cuboid joining


Ans: Isometric Sketching is a representation of an object in which all the three-dimensions are drawn at the full scale. It looks like an isometric projection. In this case, all the lines parallel to its major axes are measurable.


Isometric sketch of three cuboids


(iii)


Two cuboid joining


Ans: Isometric Sketching is a representation of an object in which all the three-dimensions are drawn at the full scale. It looks like an isometric projection. In this case, all the lines parallel to its major axes are measurable.

(iv)


The stairs formed by cuboid


Ans: Isometric Sketching is a representation of an object in which all the three-dimensions are drawn at the full scale. It looks like an isometric projection. In this case, all the lines parallel to its major axes are measurable.

2. The dimensions of a cuboid are 5 cm, 3 cm and 2 cm. Draw three different isometric sketches of this cuboid.

Ans: Isometric Sketching is a representation of an object in which all the three-dimensions are drawn at the full scale. It looks like an isometric projection. In this case, all the lines parallel to its major axes are measurable.

The three different isometric sketches of this cuboid having dimension 5 cm, 3 cm and 2 cm is shown below,


Isometric sketch 1



Isometric sketch 2

Isometric sketch 3


3. Three cubes each with a 2 cm edge are placed side by side to form a cuboid. Sketch an oblique or isometric sketch of this cuboid.

Ans: Isometric Sketch

Isometric Sketching is a representation of an object in which all the three-dimensions are drawn at the full scale. It looks like an isometric projection. In this case, all the lines parallel to its major axes are measurable

Isometric sketch of three cubes each with 2 cm edge are placed side by side to form a cuboid is given below,


Isometric sketch of three cubes


Oblique sketch is a way of representing an object in pictorial form. Basically, the circles and angles parallel to the plane of projection are considered to be the true size and shape of the object while constructing oblique sketches.

Oblique sketch of three cubes each with 2 cm edge are placed side by side to form a cuboid is given below,
