250+ TOP MCQs on Lines, Lettering and Dimensioning and Answers

Civil Engineering Drawing Multiple Choice Questions on “Lines, Lettering and Dimensioning”.

1. Which grade of pencil is used for drawing arrowheads?
a) 2H
b) 2B
c) 7H
d) H

Answer: a
Clarification: Arrowheads resembles the extent of dimensions. It should be sharply defined and uniform throughout the drawing. Generally, 3 mm in length is used. For such precision small diameter pencils are used, hence 2H is used as arrowheads.

5. What does the “Single-Stroke” lettering mean?
a) Cursive writing
b) Uniformity in letters as obtained in one stroke of the pencil
c) Writing in one stroke without lifting the pencil
d) Writing only with hard, small diameter lead-pencil

Answer: b
Clarification: Single-Stroke lettering resembles uniformity in line thickness which can be obtained in one stroke. One stroke resembles the uniform lead diameter i.e. during lettering the thickness of letters should match each other.

6. Which line is drawn to make the section evident?
a) Long-break line
b) Chain thick
c) Border line
d) Hatching line

8. What is the slope of inclined letters with the horizontal?
a) 75 degree
b) 65 degree
c) 45 degree
d) 85 degree

Answer: a
Clarification: Inclined letters are Single-stroke letters which lean to the right making a slope of 75 degree with the horizontal as per the guidance of Indian Standards. Also known as Italic lettering. Not recommended for beginners until you have mastered in vertical lettering. Inclined and vertical lettering should never appear on the same drawing.

9. In lettering ‘A’ the height of capital letter is divided in how many parts?
a) 10
b) 14
c) 16
d) 8

Answer: b
Clarification: In lettering ‘A’ type, the height of the capital letter is divided into 14 parts while in lettering ‘B’ type it is divided into 10 parts. The height of letters and numerals for engineering drawing can be selected from 2.5, 3.5, 5, 7, 10, 14 and 20 mm according to drawing size.

10. The length to height ratio of a closed filled arrow head is?
a) 1:3
b) 3:1
c) 1:2
d) 2:1

11. Guidelines for dimensions at international level on a drawing is controlled by __________
a) Bureau of Indian Standards
b) Corporate drafting standards
c) ANSI
d) ISO

Answer: d
Clarification: ISO (International Organization for Standardization), this is a World Wide organization that creates engineering standards, dimensions with approximately 100 participating countries. ANSI creates standards for North America, BIS for India, CDS for small company.
