NOCTI Drafting Exam ACTUAL EXAM COMPLETE
QUESTIONS AND CORRECT ANSWERS LATEST
UPDATE THIS YEAR
NOCTI Drafting Practice Exam (both CAD and manual drafting),. The exam typically covers basic drafting
skills, CAD commands, geometric construction, dimensioning, scaling, orthographic projection, section
views, auxiliary views, and basic ANSI standards.
SUMMARIZED EXAM COVERAGE (point form)
• Drafting Tools & Equipment – Compass, scale (architectural, civil, mechanical), triangles,
T-square, French curves, templates, erasers, lead hardness (H, HB, F, B), protractor, dividers.
• CAD (Computer-Aided Drafting) – Basic commands (LINE, CIRCLE, ARC, TRIM, EXTEND, OFFSET,
MOVE, COPY, ROTATE, SCALE, MIRROR, FILLET, CHAMFER, ARRAY (rectangular/polar), LAYER,
DIMSTYLE, OSNAP (endpoint, midpoint, center, quadrant, intersection, tangent, perpendicular,
node), POLAR tracking, ORTHO, OBJECT SNAP, GRID, SNAP, ZOOM, PAN, REGEN, EXPLODE,
BLOCK, WBLOCK, INSERT, HATCH, TEXT (single-line and multiline), DIMENSION (linear, aligned,
angular, radial, diameter, baseline, continued), LEADER, MULTILEADER, PROPERTIES,
MATCHPROP, LAYOUT, VIEWPORT (model space vs. paper space), UCS.
• Geometric Construction – Bisecting lines/angles, perpendicular lines, parallel lines, tangent arcs,
hexagon, octagon, ellipse, parabola.
• Multiview Drawing (Orthographic Projection) – Third-angle projection (used in US), six principal
views, folding lines, alignment of views (height aligns between front & side; width aligns
between front & top).
• Auxiliary & Section Views – Full section, half section, offset section, broken-out section,
revolved section, auxiliary view (primary and secondary).
• Dimensioning – ANSI standards: unidirectional (horizontal text), aligned (text aligned with
dimension line), arrowheads (closed, open, oblique), extension lines (1/16″ gap from object,
extend 1/8″ beyond dimension lines), leader lines, tolerances (bilateral, unilateral, limits), dual
dimensioning (metric/inch), chain vs. baseline vs. direct dimensioning.
• Scaling – Architectural scale (1/4″ = 1′-0″), civil engineer’s scale (1″ = 10′, 20′, etc.), mechanical
scale (full, half, quarter, etc.), metric scales.
• Line Types & Lineweights – Object lines (thick, continuous), hidden lines (medium, dashed),
center lines (thin, long-short-long), section lines (thin, angled), dimension lines, extension lines,
cutting plane lines, phantom lines, break lines.
• Basic Design & Layout – Title block, border, revision block, parts list/BOM, drawing number,
scale notation, material callout.
• Geometric Dimensioning & Tolerancing (GD&T) – Basic symbols: flatness, straightness,
circularity, cylindricity, perpendicularity, parallelism, angularity, position, concentricity (basic),
datum feature, feature control frame.
• Print Reading & Interpretation – Identify features, tolerances, surface finish symbols, welding
symbols (basic), notes (general/local).
• 3D Modeling (basic) – Extrude, revolve, sweep, loft, boolean operations (union, subtract,
intersect).
• Working Drawings – Assembly drawings, detail drawings, subassembly, family of parts.
• Ethical & Professional Practices – Intellectual property, design changes, checking, approval,
archiving.

QUESTION 1: A drafter is creating a multiview drawing using third-angle projection. The view that is
placed to the left of the front view is the:
A) Top view
B) Bottom view
C) Left side view
D) Right side view
Answer: D – In third-angle projection, the right side view is placed to the right of the front view; the left
side view is placed to the left of the front view. Wait – the question says “placed to the left of the front
view” – that is the left side view. The answer should be (C) Left side view . Correction: Right side view is
on the right; left side view is on the left.
QUESTION 2: Which CAD command is best suited to create a rectangular array of holes in a plate?
A) COPY
B) MOVE
C) ARRAY
D) OFFSET
Answer: C – Array creates multiple copies in a pattern (rectangular or polar).

QUESTION 3: In a dimension string, the dimension lines are drawn with:
A) Arrowheads at each end
B) Dots instead of arrows
C) No arrowheads if the dimension is over 12″
D) A tick mark only
Answer: A – Standard ANSI dimension lines have arrowheads at the ends.
QUESTION 4: A drafter is using an architect’s scale to measure a line that represents 8 feet. On a 1/4″
scale, how many inches on the drawing would represent 8 feet?
A) 1 inch
B) 2 inches
C) 4 inches
D) 8 inches
Answer: B – 1/4″ = 1′-0″, so 8′ = 8 × 1/4″ = 2″.
QUESTION 5: To show the interior shape of a part without removing the entire front half, a drafter
would use a:
A) Full section
, Page 4 of 104
B) Half section
C) Broken-out section
D) Revolved section
Answer: B – A half section removes one quarter of the part, showing both interior and exterior.
QUESTION 6: In CAD, which object snap mode allows you to snap to the exact middle of a line?
A) ENDPOINT
B) MIDPOINT
C) CENTER
D) NODE
Answer: B – MIDPOINT snaps to the geometric center of a line or arc.
QUESTION 7: The type of line that indicates a hidden feature is:
A) Continuous thick line
B) Dashed (medium) line
C) Center line (long-short-long)
D) Phantom line
Answer: B – Hidden lines are made of medium-weight dashes.
