1. Which line type is conventionally used in technical drafting to
represent the visible edges and contours of an object in an
orthographic view?
A. Centerline
B. Object line
C. Construction line
D. Phantom line
Object lines are used to show visible edges, surfaces, and contours of the
object being represented. They are normally drawn with a relatively
heavy, continuous line weight so the primary shape is immediately
distinguishable.
2. In an engineering drawing, what is the primary purpose of a
dimension line?
A. To indicate hidden surfaces
, B. To identify the material specification
C. To indicate the measured extent of a feature
D. To show the direction of projection
A dimension line establishes the extent of a measured feature and is
normally terminated by arrowheads or another approved terminator.
The associated numerical value communicates the required size.
3. Which orthographic projection view normally shows an object's
width and height?
A. Top view
B. Right-side view
C. Rear view
D. Front view
The front view generally represents the width and height of an object.
The top view represents width and depth, while a side view normally
represents depth and height.
4. What is the primary purpose of a title block on a technical drawing?
A. To show hidden lines
B. To provide only the drawing scale
C. To identify the drawing and provide essential administrative
information
D. To replace general notes
,The title block typically contains information such as the drawing title,
identification number, scale, date, drafter or designer, revision
information, and organizational details.
5. A drawing is prepared at a scale of 1:4. What does this scale
indicate?
A. The drawing is four times larger than the object
B. The object is one-fourth the size of the drawing
C. The drawing represents the object at one-fourth of its actual
size
D. Four drawing units equal one object unit only when dimensioned
A 1:4 scale means one unit measured on the drawing represents four
corresponding units on the actual object. Thus, the drawing is one-
quarter of the object's actual size.
6. Which drafting instrument is primarily designed to draw circles and
arcs of specified radii?
A. T-square
B. Triangle
C. Scale
D. Compass
A compass is designed to construct circles and arcs using a selected
radius. Proper compass adjustment is important for producing accurate
geometric constructions.
, 7. In computer-aided drafting, what does CAD stand for?
A. Computerized Architectural Documentation
B. Computer-Aided Design
C. Construction Analysis Drawing
D. Computerized Assembly Development
CAD stands for Computer-Aided Design. CAD systems are used to create,
modify, document, analyze, and communicate technical designs
digitally.
8. Which CAD object type is most appropriate for representing a
straight, continuous edge between two specified points?
A. Spline
B. Arc
C. Line
D. Hatch
A line object represents a straight segment between two points. It is one
of the fundamental geometric entities used to construct technical
drawings.
9. What is the principal function of a section view?
A. To enlarge the title block
B. To eliminate all dimensions
C. To reveal internal features that may not be clearly visible
externally
D. To show only the object's exterior finish
