13. What are the different components of drawing sheet?
Ans: Different components of the drawing sheets are: Border lines, Title Block , Notes, Revision columns, Drawing area, Folding Marks, Area identification marks, Drawing Number, Projection angle symbol, Names / Signatures of persons who have Drawn, Designed, Design Checked, Recommended, Approved, Scale, Address, Title of Drawing etc.
14. What are dimension lines?
Ans: Dimension lines are thin continuous lines with arrow heads / ticks etc at ends indicating the dimension between points.
15. What is an Ammonia print and what is a blue print?
Ans: Where background of drawing sheet print is white and letters & line work are blue it is called Ammonia print.
Where background of drawing sheet print is blue and letters & line work are white it is called Blue print.
16. What is first angle projection? What is third angle projection?
Ans: a. When the object is placed in the 1st quadrant such that it is between the projection plane and the observer, the projections so obtained are called first angle projection.
b. When the object is placed in the 3rd quadrant and the places of projections are in between the object and the observer, the projections so obtained are called third angle projection.
17. Which projection do you use in preparation of civil drawings?
Ans: First angle projection is used in preparation of Civil Drawings.

Ans: To obtain and exact information regarding the location of the building with respect to north direction.
21. What is the general building height?
Ans: The general building height is 3000 mm for Regular buildings, 3500 mm for Office building.
22. What is the proportion of Arrow in a drawing?
Ans: The proportion of Arrow in a drawing is 1:3
23. What are the different types of scales?
Ans: Different types of Scales are:
a. Enlarged scales: When drawings drawn are larger than the actual size, they are known as enlarged scale.
b. Reduced scale: When drawings drawn are smaller than actual size, they are known as reduced scales.
24. What are projection rays?
Ans: The imaginary rays joining the corners of the object with the observer’s eyes are known as projection rays.
