What is the purpose of the engineering drawing Handbook?
This handbook is prepared with the primary aim to elaborate necessary basic rules and regulations of engineering drawing that is necessary for students of every engineering discipline. This book is for beginners to introduce them with different elements of engineering drawing.
What are the methods of bisecting in engineering drawing?
Common for all Engineering Trades Exercise 1.4.13 Engineering Drawing Method of bisecting practice of square - rectangle - parallelogram - rhombus & circle Follow the procedures and construct quadrilaterals on A3/ A4 sheets. Procedure Square 1 1st method (Fig 1): A square of side 50 mm by erecting perpendicular. • Draw a line AB 50 mm long.
What information is conveyed in an engineering drawing?
An engineering drawing conveys many different types of information of which the most important thing is the shape of the object. Fig 1 shows a sample drawing. In this drawing the shape of the part is represented by three views. For an untrained person it will be very difficult to conceive the shape of the object from the above drawing.

What are the three types of engineering drawings?
Orthographic projections: are drawn as multi view drawings, which show flat representations of principal views of the subject. Oblique Projections: actually show the full size of one view. Axonometric Projections: are three-dimensional drawings, and are of three different varieties: Isometric, Dimetric and Trimetric.
What are the 4 types of technical drawing?
There are many types of technical drawings, including: 3D drawings (isometric, perspective) • Exploded-view 3D drawings • Complete working drawings • Detail drawings (2D orthogonal projections) •Diagrams are another form of technical drawing with looser, less universal standards.
What are drawing standards?
Drawings are used by engineers and manufacturing technologists to communicate their ideas and hence good engineering drawings follow conventions which are referred to as drawing standards.

What is engineering drawing sheet?
Drawing sheet is a white paper on which an object is drawn which is available in various sizes. The sheet used for engineering should be of good quality. It should be white in color with uniform thickness with must resist the easy torn of paper. The surface of sheet must be smooth.
How many types of lines are there in engineering drawing?
For general engineering drawings, the types of lines recommended by the Bureau of Indian Standards shown in table 2 must be used. The thickness of the lines must be chosen according to the type and size of the drawing from any of the six groups given in Table 1.
What is engineering drawing and its types?
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component.
What is isometric and orthographic?
Isometric: a method of representing three-dimensional objects on a flat surface by means of a drawing that shows three planes of the object. Orthographic: a method for representing a three-dimensional object by means of several views from various planes.
Why are symbols used in engineering drawings?
For example, engineering symbols are used in technical drawings to convey the specific geometry and other details about pieces of equipment or components. To limit errors caused by personal interpretation, engineering drawings and diagrams are governed by standardized language and symbols.
What is graphic communication?
Graphic communication involves using visualmaterials to relate ideas. Drawings, photographs, slides ,transparencies, and sketches are all forms of graphiccommunication. Any medium that uses a graphic imageto aid in conveying a message, instructions, or an idea isinvolved in graphic communication.
What is a quadrilateral?
Quadrilateral is a plane figure bounded by four sides andfour angles . Sum of the four angles in a quadrilateral is(interior angles) equal to 360°. The side joining oppositecorners is called diagonal. To construct a quadrilateral outof four sides, four angles and two diagonals a minimum offive dimensions are required of which two must be sides.Quadrilaterals are also referred as Trapezium. (Fig 1)
What is perspective in art?
Perspective (from Latin: perspicere "to see through") inthe graphic arts is an approximate representation, generallyon a flat surface (such as paper), of an image as it is seenby the eye. The two most characteristic features ofperspective are that objects appear smaller as theirdistance from the observer increases; (Fig 1) and that theyare subject to foreshortening, meaning that an object'sdimensions along the line of sight appear shorter than itsdimensions across the line of sight.
What is functional dimension?
Functional dimension (F): It is a dimension which isessential to the function of the component or space. Theyare generally shown with limits. (Fig 1)
How many people will be trained in India by 2020?
The Government of India has set an ambitious target of imparting skills to 30 crores people, one out of every four Indians, by 2020 to help them secure jobs as part of the National Skills Development Policy. Industrial Training Institutes (ITIs) play a vital role in this process especially in terms of providing skilled manpower. Keeping this in mind, and for providing the current industry relevant skill training to Trainees, ITI syllabus has been recently updated with the help of Mentor Councils comprising various stakeholder's viz. Industries, Entrepreneurs, Academicians and representatives from ITIs.
