1. Use isometric dot paper and make an isometric sketch for each one of the
given shapes:
(i)
Ans: Isometric Sketching is a representation of an object in which all the threedimensions 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,
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 threedimensions 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,
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,
4. Make an oblique sketch for each one of the given isometric shapes:
(i)
Ans: 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.
