PREFACE

It gives me immense pleasure in presenting this Question Bank to you. Question Bank aims to help you
consolidate your learning better and identify the areas of weakness. The purpose is to significantly improve
your performance in the Board examinations by giving practice material for applying the concepts learned in
classroom teaching. This enables you to know the standard, recent trends and patterns of questions of the
Board examination.
This Question Bank is designed based on the latest syllabus by the CBSE for the academic year 2016-17. It
is a collection of last 5 years question papers, model question papers with answer key, blue print, Tips for the
exam, how to score well, practical exam blue print and sample paper, etc.
The most important element in the preparation for any examination is the depth of learning. These questions
are no substitute for exhaustive study, but they provide you a safe environment to illustrate specific points,
especially for the reorientation before the examination.
I hope that you will use this Question Bank to sharpen your skills to handle the Board Examination.

My best wishes for the Board examinations !

 Practice free hand sketching as much as possible, apart from sketching using tools. This will help you get
into the flow of drawing.

 In every question first determine exactly what is being asked as often Engineering Graphics exam questions
are confusing.

 Under Isometric projections question on frustum will be asked in vertical position only. Also hidden lines
will not be required.

 Master each type of assembly and dis-assembly drawing, first practicing in free hand but also doing it
with tools.

 Practice and improve your visualization skills as this is an important way to score in the questions for
projections.

 In questions on Assembly drawings, half sectional front view will definitely be asked.
 Revise the different symbols, line styles and other details that you will need to answer questions in the

exam regarding a full drawing.
 Once you are thorough with the concepts in free-hand, practice important questions with full tools so as

to increase your speed.
 Apart from drawing practice and preparation, study theory by making small notes of the important topics

in your own words. This will help you answer multiple choice questions during the exam.
 As the exam approaches practice sample papers and previous year papers and go through your short

notes on theory topics.

ENGINEERING GRAPHICS (Code No. 046)

ISOMETRIC DRAWING AND THIRD (MISSING) VIEW
The Isometric Projection has to be drawn to the Isometric Scale.
Instead of the isometric scale, the full-size scale is used to draw the Isometric View of an object.
The Isometric View is about 22.5% large than the Isometric Projection. For the sake of distinction,
the view is called ‘ISOMETRIC DRAWING/VIEW’.
General Steps:

a) Draw the Front View and Side View of the Machine Block to scale 1:1, according to the
dimensions in the given views.

b) Project the Top View, [the 3rd (missing) view], from the Front and Side Views, as shown in
figure below. Show the dimensions.

Engineering Graphics Practical 33

c) Proceed step by step to construct the Isometric Drawing from the views. Rub off
unnecessary lines, to show a clear Isometric Drawings of the Machine Block. The hidden
lines are not to be shown.
