1. Which line type is commonly used to represent hidden features in a
civil drafting plan?
A. Continuous thick
B. Center line
C. Dashed
D. Phantom line
Dashed lines are standard for representing hidden or obscured
features in civil drafting.
2. What is the purpose of a benchmark in surveying?
A. To mark the highest point of a site
B. To provide a reference elevation
C. To locate property corners
D. To indicate construction limits
, A benchmark is a fixed point of known elevation used as a reference
for all other vertical measurements.
3. Which scale is most commonly used for site plans in civil drafting?
A. 1:10
B. 1:50
C. 1:100
D. 1:200
1:200 is a typical scale for site plans, allowing adequate detail while
fitting the plan on a standard sheet.
4. In AutoCAD, which command is used to create parallel lines at a
specific distance?
A. Trim
B. Offset
C. Fillet
D. Offset
The Offset command generates a line, arc, or curve at a uniform
distance from the original object.
5. In civil drafting, which symbol represents a manhole?
A. Square
B. Triangle
C. Hexagon
D. Circle with an “MH” label
, Manholes are represented as circles labeled “MH” to indicate access
points to underground utilities.
6. The process of converting field survey data into a digital drawing is
called:
A. Drafting
B. Digitizing
C. Plotting
D. Tracing
Digitizing refers to transferring survey measurements into a CAD
system to create an accurate drawing.
7. Which of the following is the primary purpose of contour lines on a
topographic map?
A. Indicate vegetation type
B. Show property boundaries
C. Show elevation changes
D. Represent underground utilities
Contour lines connect points of equal elevation to illustrate the
terrain's shape.
8. In civil engineering, the slope of a road is expressed as:
A. Percentage or ratio
B. Degrees only
C. Both percentage and ratio
D. Radians
, Slopes are typically expressed as a percentage (rise/run × 100) or a
ratio (rise:run).
9. Which survey instrument is used to measure horizontal and vertical
angles?
A. Level
B. GPS
C. Theodolite
D. Total station
A theodolite measures both horizontal and vertical angles for precise
surveying.
10. When plotting a subdivision plan, property lines should be
drawn:
A. Thicker than buildings
B. Dashed
C. Continuous thin lines
D. Dotted
Property lines are usually continuous thin lines to distinguish them
from heavier construction lines.
11. Which coordinate system is most commonly used in civil drafting
in the U.S.?
A. Polar coordinates
B. Cartesian coordinates
C. Spherical coordinates
