21.Based on the Blueprint, machinist is about to drill a 16mm diameter hole on a piece of 100mmx120mm flat bar. Which line in the alphabet of lines must he look for first?
A. Hidden Line
B. Phantom Line
C. Center Line
D. Section Line
Answer: C. Center Line
Hidden Line- also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen.
Phantom Line- are long-short-short-long lines most often used to show the travel or movement of an object or a part in alternate positions.
Center Line- denote a circular feature such as a shaft or a hole. A rectangular feature seen on an elevation of a drawing could be identified either as a circular feature or a rectangular feature.
Section Line- show the kind of material from which the part is to be constructed. The material may not be indicated symbolically when its exact specification must also be shown elsewhere on the drawing.
22.When drawing the different views in orthographic projection, a drafter must acknowledge that there are hidden edges that must be emphasized in order to produce complete drawing information. Which line is he going to use?
A. Hidden Line
B. Section Line
C. Center Line
D. Object Line
Answer: A. Hidden Line
Hidden Line- are used to show surfaces that are not directly visible. All surfaces must be shown in all views. If an edge or surface is blocked from view by another feature, it is drawn using a hidden line.
Section Line- also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen.
Center Line- denote a circular feature such as a shaft or a hole. A rectangular feature seen on an elevation of a drawing could be identified either as a circular feature or a rectangular feature.
Object Line- thick, solid lines show the visible edges, corners, and surfaces of a part.
23.A drawing teacher on a local high school was discussing a feature on which the surface appears to have imaginary cut along the cutting plane line. Which line is she going to apply to the surface where the cutting plane cut through?
A. Center Line
B. Dimension Line
C. Section line
D. Invisible Line
Answer: C. Section line
Center Line- denote a circular feature such as a shaft or a hole. A rectangular feature seen on an elevation of a drawing could be identified either as a circular feature or a rectangular feature.
Dimension Line- line is a fine, dark, solid line with arrowheads on each end. It indicates direction and extent of a dimension
Section line- lso known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen.
Invisible Line- are used to show surfaces that are not directly visible. All surfaces must be shown in all views. If an edge or surface is blocked from view by another feature, it is drawn using a hidden line.
24.There are six principal views of an object, TV, FV and RSV, RV, LSV, BV. Which the views are accepted by the industry as standard multi-views according to the 3rd angle projection?
A. Top view, front view, and right side view
B. Side view, bottom view, and rear view
C. Right side view, left side view, and bottom view
D. Front view, rear view and side view
Answer: A. Top view, front view, and right side view
25.A group of students is experimenting on views in orthographic projection. They extract first the front view of a simple object using a transparent material as discussed by their teacher. What technique are they using?
A. Glass box technique
B. Onion skin technique
C. Japanese paper technique
D. Polycarbonate technique
Answer: A. Glass box technique
Glass box technique- the image of the object is projected on the sides of the box. The box is unfolded. The sides of the box are the principal views.
Onion skin technique- is used to preview the previous and subsequent drawings with a translucent mode.
Japanese paper technique- These elegant Japanese art style is known as nihonga (Japanese painting) | Japanese paper cutting is called Kirie or Kirigami (literally meaning cut picture)
Polycarbonate technique- is a method that involves shape to a soft, flexible state, then fitting it around a custom mold
26.Orthographic projection goes farther than right angle. A drafter can actually extract views for more details of the object provided that the projectors are parallel to each other and normal to the plane of projection. The additional plane is called:
A. Frontal plane
B. Auxiliary plane
C. Profile plane
D. Horizontal plane
Answer: B. Auxiliary plane
Frontal plane - is the plane onto which the Front View (FV) of the multi-view drawing is projected. Front view of an object shows the width and height dimensions. Horizontal plane of projection is the plane onto which the Top View of the multi-view drawing is projected.
Auxiliary plane- a type of orthographic projection used to determine the true size and shape of inclined and oblique surfaces of objects
Profile plane- plane is vertical in position, and may be used as a plane of projection. A projection on the profile plane is called a profile view, or end view, or sometimes edge view,
Horizontal plane- is the plane onto which the Top View of the multi-view drawing is projected
27.All of objects have distinct limits which can be considered as the width, depth, and height. So when a drafter is working on the difference in elevation between any two points, measured as the perpendicular distance between a pair of horizontal lines, he is now engaged in the_ of the object?
A. Depth
B. Height
C. Width
D. Bottom
Answer: C. Width
Depth- is measured at the middle of the length, from the top of the keel to the top of the deck beam at the side of the uppermost continuous deck.
Height- he measurement from base to top
Width- the measurement or extent of something from side to side.
Bottom- the lowest point or part of something.
28.When an engineer is engaged in the preparation of views prior to formal drafting activities, he practically bases his information on actual and accurate observation. This process is regarded as:
A. Pencil and paper exercise
B. Glass box technique
C. Orthographic sketch
D. Order drawing
Answer: C. Orthographic sketch
Pencil and paper exercise-
Glass box technique- the image of the object is projected on the sides of the box. The box is unfolded. The sides of the box are the principal views.
Orthographic sketch- common method of representing three-dimensional objects, usually by three two-dimensional drawings in each of which the object is viewed along parallel lines that are perpendicular to the plane of the drawing.
Order drawing- property settings specify in which order the markers for the selected column should be drawn.
29.After all the views are given, the drafter must now work on the real form of the objects based on actual result of the orthographic projection. This process is called:
A. Pictorial drawing
B. Depth dimensioning
C. Height dimensioning
D. Center dimensioning
Answer: C. Pictorial drawing
Pictorial drawing- A view of an object (actual or imagined) as it would be seen by an observer who looks at the object either in a chosen direction or from a selected point of view. Pictorial sketches often are more readily made and more clearly understood than are front, top, and side views of an object.
Depth dimensioning- process of putting the dimenson for depth
Height dimensioning - process of putting the dimenson for height
Center dimensioning- process of putting the dimenson for center location on the object
30 In isometric drawings, the angle used to aid the construction of the object is 30 degrees and all vertical line are equal lengths or scale but in oblique drawing the angle used is:
Answer: B. 45 degrees
40 degrees
45 degrees
30 degrees
60 degrees
Notes:
ALPHABET OF LINE

Hi. I'm Franz. A third-year college student taking Bachelor of Technical Teacher Education Major in Automotive Technology at the time being. I am doing this blog for the purpose of reviewing myself for the Licensure Examination Test. You might tell that it's way too early for me to review. That is also why I want to take advantage of it. With no pressure, here is where I will post and review 10 questions daily. I will also compile notes, research, and explanations I've gathered. With my friends, we're also planning to have a weekly review in the future. Since you already have an access to this blog, I am hoping that you put this to good use. You can review this daily like how I do, read this in one go, or occasionally when you're on a bus or on your couch. This blog is still in the process. Questions and key answers ...
