ENGINEERING GRAPHICS ESSENTIALS EXAM QUESTIONS WITH CORRECT ANSWERS LATEST
UPDATE 2026
Orthographic projection - Answers enables us to represent a 3D object in 2D.
6 Principle Views of an Orthographic Projection - Answers top, front, right
left, rear, bottom
3 most common views (standard views) - Answers top, front, right side
The _____ view shows the most features or characteristics of the object. It contains the least
number of hidden lines. - Answers front
Visible lines - Answers represent visible edges and boundaries
continuous and thick weight
Hidden Lines - Answers represent edges and boundaries that cannot be seen
dashed with medium thick weight
Center Lines - Answers represent axes of symmetry and are important for interpreting
cylindrical shapes
long dash-short dash with thin weight
Phantom Lines - Answers used to indicate imaginary features
to indicate alternate positions of moving parts and adjacent positions to related parts
long dash-short dash-short dash with thin weight
Line Type Precedence -> if two liens occur in the same place, the line that is considered to be
the least important is omitted.
Lines in order of importance: - Answers 1. Cutting plane line (highest importance)
2. Visible line
3. Hidden line
4. Center line
Projection symbol -> In the United States, we use ___ angle projection to create an orthographic
projection. - Answers 3rd
Europe and elsewhere use 1st angle projection
, An orthographic projection, complete with all the dimension and specifications needed to
manufacture the object is called a _________. - Answers detailed drawing
All lines used in dimension are drawn thin so that ? - Answers they will not be confused with
visible lines
Dimension Line - Answers thin solid line terminated by arrowheads which indicate the direction
and extent of a dimension
a number is placed in the middle to specify size
Extension Line - Answers thin solid line that extends from a point on the drawing to which the
dimension refers
the dimension line meets the extension line usually at right angles
there should be a visible gap between this line and the object
Leader Line - Answers a straight inclined thin solid line that is usually terminated by an
arrowhead.
It is used to direct a dimension, note, symbol, item number, or part number to the inteded
feature on a drawing
It is not horizontal or vertical except for a short portion extending to the first or last letter of a
note.
_____case letters should be used for all lettering unless the opposite is required. - Answers
Upper
__________ replace text and are used to minimize language barriers. - Answers Dimensioning
symbols
There is no such thing as an "________" measurement. - Answers Exact
A tolerance is the amount a dimension is allowed to vary.
Sectional views -> Why do we take an imaginary cut through the object and remove a portion? -
Answers so that the inside features may be seen more clearly
Cutting Plane Line - Answers is used to show where the object is being cut
(1st order of precedence)
arrows are placed at the ends to indicate direction of site
arrows point to the portion being kept
