Correct Answer : dimension lines
Explanation : Out lines, dotted lines and cutting plane-lines are drawn using 2mm thickness lines. Whereas centre lines, section lines, dimension lines, extension lines, construction lines, leader lines, short break lines and long-break lines are drawn using 1mm thickness lines.
Correct Answer : H
Explanation : Initial work and construction lines are drawn using H pencil. 2H pencil is used for outlines, dotted lines, dimension lines and arrowheads. 3H, 4H are used for centre lines and section lines.
Correct Answer : 3H or 4H
Explanation : Centre lines, section lines are drawn using 3H or 4H pencil. Outlines, dotted lines, section-plane lines, dimension lines and arrow heads are drawn using 2H. These different pencils give different shades which give different importance to lines in drawing.
Correct Answer : Engineering change orders
Correct Answer : All of the above
Correct Answer : i, iii
Explaination : The two systems of placing dimensions are aligned system and unidirectional system. In the aligned system, the dimension is placed perpendicular to the dimension line. In the unidirectional system, all dimensions are placed such that they can be read from the bottom of the drawing sheet.
Correct Answer : Placed by breaking the dimension line in the middle
Explanation : In unidirectional system all dimensions are placed such that they can be read from the bottom of the drawing sheet. The dimension lines are broken near the middle for inserting the dimensions. This is used in mainly large drawings.
Correct Answer : Placed perpendicular to the dimension line
Explanation : In the aligned system the dimension is placed perpendicular to the dimension line. The dimensions should be placed near the middle and above, but clear of the dimension lines.
Correct Answer : Design process
Correct Answer : Designer's intent
Correct Answer : Assembly
Correct Answer : 1:3
Explanation : The standard ratio of height to length of an arrow in dimensioning should be kept only 1:3. Even if there are so many types of arrows like oblique stroke, closed, open small open circle etc. Generally closed and filled arrowhead is widely used and with 1:3 ratio.
Correct Answer : material
Explanation : Dimensioning relates to the geometry of machine part/plot but not the material, transparency, physical, mechanical, chemical properties of machine part/plot. Other than the dimensions are placed near the title block of drawing sheet if necessary.
Correct Answer : Every dimension should be written to the left side of the drawing
Explanation : There is no such rule that the dimensions should be placed only on left side of drawing because it may not possible to represent every dimension only on left side. So, it is given flexibility that dimensions can be given any side of drawing but none should be given twice or more.
Correct Answer : Erection plans
Correct Answer : Elliptical
Correct Answer : Product data management
Correct Answer : Outside the view
Explanation : It is advised to place the dimensions outside the view. This will bring a clear picture of the view and will help in the understanding of the dimensions. Placing the dimensions outside the view gives a cleaner look.
Correct Answer : 10
Explaination : From the front view it is clear that the circle has diameter 20 mm. Hence its radius will be 10mm. The dimension 10mm in the side view is just a repetition of this information. Repetitive dimensions are redundant and they need to be avoided.
Correct Answer : Extension line
Explanation : The center line can be used as an extension line. With the help of the center line as an extension line, we can dimension the distance between the centers of the circles from the outline view of the object. This helps in drawing the circle accurately.
Correct Answer : 20
Explaination : The dimension 20mm is given without using the extension line. The outline of the view is used to dimension the line. This is not usually favoured. Always use extension line and place the dimension line in between the extension lines.
Correct Answer : φ
Explanation : Since the true shape of the cylinder is a circle from one view, we used the symbol φ followed by the dimension figure while dimensioning it in the view where it is seen as a rectangle. The cross-section of the rectangle is square then the symbol • followed by the dimension figure is used.
Correct Answer : O Snaps
Correct Answer : Block Definition Dialog

Correct Answer : ratio of the length in drawing to the actual length
Explanation : Representative fraction is the ratio of the length of the object represented on drawing to the actual length of the object represented.
Correct Answer : 1/20
Explanation : The scale of the drawing is given as 1:20 that is a reducing scale, this means dimensions are made to 1/20th of full size. So the representative factor is that dimension in drawing to actual dimension. R.F. = (1/20)/1 = 1/20.
Correct Answer : 15
Explanation : The scale of the drawing is given as 15:1 that is an enlarging scale, this means dimensions are increased to 15 times of actual ones. So the representative factor is that dimension in drawing to actual dimension. R.F. = 15/1 = 15.
Correct Answer : Leader
Correct Answer : The Finished plot
Correct Answer : Different line widths convey different information
Correct Answer : Full size scale
Explanation : A full size scale is a type of scale in which the length of the drawing and the actual length of the object is of the ratio 1:1. Hence by definition, its representative fraction is 1:1. In full size scale, the drawing is drawn with the actual measurements.
Correct Answer : 1:0.2
Explanation : Enlarging scale means that the drawing is drawn with the bigger dimensions in comparison to the actual dimensions of the object. A representative fraction of 1:0.2 means 5:1, i.e. the drawing is five times bigger than the actual object. Hence the scale is enlarging scale.
Explanation : The representative fraction 1:3 indicates that the dimension of the drawing is one-third of the actual object. Since the drawing is smaller than the actual object, this type of scale is called a reducing scale.
Correct Answer : 3:5
Explanation : Enlarging scale means that the drawing is larger than the actual object. Hence the representative fraction will be greater than unity. For reducing scale the representative fraction is less than unity.
Correct Answer : 1:1
Explanation : A scale which is neither enlarging nor reducing is called as full size scale. The representative fraction of a full size scale is 1:1. In full size scale, the drawing is made just as the actual dimensions of the object.
Correct Answer : 1/500
Explanation : Length of the scale = Representative fraction x Maximum length, 10 cm = Representative fraction x 5000 cm, Representative factor = 1/500.
Correct Answer : 10 cm
Explanation : Length of the scale = Representative fraction x Maximum length, Length of scale = 4/50 x 100 cm, Length of scale= 8 cm.
Correct Answer : 7
Explanation : Whatever the representative factor may given, we just require a number of units to divide the line in scale. Representative factor is only needed to find the length of the scale. Length of the scale = Representative fraction x Maximum length.
Correct Answer : The distances between outside walls and interior walls
Correct Answer : 7.5 cm
Explanation : Length of the scale = Representative fraction x Maximum length. Length of the scale = 3/40 x 100 cm = 7.5 cm. That is to draw a scale for 100 cm with 3/40 R.F. We need to draw a 7.5 cm length line and divide to 10 decimeters.
Correct Answer : LMC
Correct Answer : 3
Explanation : Using plain scale we can accommodate 2 units (example: yard, feet). But with the diagonal scale we can accommodate 3 units (example: yard, feet and inch). It is possible by the principle of diagonal division.
Explanation : Vertical divisions are related to how many centimeters take a decimeter. It is 10. Or anywhere in a diagonal scales vertical division are dependent of 2nd and 3rd unit which we use in drawing diagonal scale.
Correct Answer : 1/2236
Explanation : Area of plot in drawing is 14 x 5 = 70 sq cm (equivalent to 35000 sq m). So 1 sq cm =35000/70 = 500 sq m. 1 cm = square root of 500 m = 22.3 m (equivalent to 1 cm). Representative fraction = 1/ (22.36 m) =1/ (2236 cm).
Correct Answer : Diagonal scale
Explanation : Minute divisions are accurately measured by using diagonal scales. Diagonal scales are also when three different units of measurements are needed to be measured. With the help of these scales, we can get a relation between three different units.

Correct Answer : 75⁰
Explanation : 45⁰ can be drawn using 45⁰ Set-square, and 30⁰, 60⁰ can be drawn using 30⁰ – 60⁰ Set-square, but to draw 75⁰ degrees we need both Set-squares. That is only if we keep 30⁰ of set-square adjacent with 45⁰ set-square we can get 75⁰. And also multiple angles can be achieved using protractor.
Correct Answer : 125⁰
Explanation : 15⁰ can be made by keeping 45⁰ and 30⁰ adjacent to each other on the line perpendicular to the line for which 15⁰ is made. Likewise for 105⁰ and 165⁰ also if we just change the alignment with the required line it possible. But to make 125⁰ there is no such combination available for Set-squares.
Correct Answer : 25mm
Explanation : A normal Small bow compass is capable of drawing circles less than the 25mm radius. This is because of the arrangement of a screw in between the legs of the compass. But any other normal compass can’t give us perfect circles whose radius is less than 25mm.
Correct Answer : eight
Explanation : The cardboard scales are available in a set of eight scales. They are designated from M1 to M8 which has scale of 1:1, 1:2.5, 1:10, 1:20, 1:50, 1:200, 1:300, 1:400, and 1:1000. These are standard scales used.
Correct Answer : French curves
Explanation : French curves are used for drawing curves which can’t be drawn with a compass. A faint freehand curve is first drawn through the known points. Longest possible curves exactly coinciding with the freehand curve are then found out from the French curve. Finally, a neat continues curve is drawn with the aid of the French curve.
Correct Answer : 297 mm x 420 mm
Explanation : 210 mm x 297 mm is A4 size, next one is A3 (297 mm x 420 mm), which came doubling along the width. And the next size is obtained by doubling the width i.e. A2 (420 mm x 594mm) and so on.
Correct Answer : softer
Explanation : The increase in hardness is shown by the value of the figure put in front of the letter H, 2H, 3H, and 4H etc. Similarly, the grade becomes softer according to the figure placed in front of the letter B, 2B, 3B, and 4B etc.
Correct Answer : Represents the direction to which sheet is placed
Explanation : The sheet may be placed in any direction but within the sheet, the drawing should be specified particularly for reproduction purpose, the main purpose is to facilitate positioning of the drawing and parts in it.

Explanation : The size of the title block is 185mm x 65 mm which is recommended by B.I.S. (Bureau of Indian Standards), where 25mm x 10mm is for scale in drawing sheet. Within the title box, there will be so many sections divided like Name of the firm, Drawing No, Title, etc.
Correct Answer : ii), i), iv) and iii)
Explaination : For drawing, circle center should be the primary thing. Make the circle and through it draw horizontal and vertical center lines. Later we add four radial lines between them and then the paper maybe revolved for easy wrist motion to enable drawing.
Correct Answer : ii), iv), i) and iii)
Explaination : Holding the pencil should be primary thing, getting a clear view on the drawing is next after we have to just draw with a light sketch so that we can understand how the sketch will be, and finishing with a dark sketch.
Explanation : French curves are used for drawing curves which cannot be drawn with a compass. Since we are just making a rough sketch of our drawing beforehand, for the actual drawing there is no need for French curves. The remaining are primary requirements to sketch any drawing.
Correct Answer : Center line
Correct Answer : Offset
Correct Answer : Non-isometric lines
Correct Answer : hardness
Explanation : Drawing pencils are graded according to the increase in relative hardness. They are marketed with the labeled as H, 2H, 3H, 4H, 5H, 6H etc. These grades are used for getting accurate, clean and neat drawings.

Correct Answer : U.S. customary units
Correct Answer : Structure location plans
Explanation : The scale given is 2:1 (enlarging scale) that is the drawing is made 2 times of actual dimensions. So we have to divide the drawing length with 2. 20 mm / 2 =100 mm and 1 cm =10 mm. The actual length in cm is 10 cm.
Correct Answer : 20 cm
Explanation : The scale is reducing scale. The ratio of length of drawing to actual length gives the representative factor. 10 cm / actual length = 0.5, actual length = 10 cm/0.5 = actual length = 20 cm (or) 200 mm.
Correct Answer : 30
Explanation : Representative factor is the ratio of the length represented in drawing to the actual length. Here given actual length is 1 cm and length of drawing is 30 cm. R.F. = 30 cm/1 cm = 30.
Correct Answer : 1:5, 1/5
Explanation : Given that the ratio of actual length to length of drawing which is reciprocal of R.F. So the R.F. for given values is 1/5. From the given information it can be understood that the actual object is 5 times larger than the drawing, so the scale is reducing scale i.e. 1:5.
