Question 1
What is the fundamental purpose of a CAD system?
A. To create physical prototypes automatically
B. To generate and manage digital design data
C. To replace all manual drafting entirely
D. To estimate manufacturing costs
🟢B
🔴 Explanation: The core purpose of a CAD system is to create, modify, analyze, and
optimize a digital model of a design. While it facilitates other tasks, its primary function is
the generation and management of this digital design data.
Question 2
In orthographic projection, how many principal views are typically used to describe a
three-dimensional object?
A. Two
B. Three
C. Six
D. Eight
🟢C
🔴 Explanation: There are six principal views in orthographic projection: front, back, top,
bottom, left, and right. This set allows for a complete description of the object's geometry.
Question 3
Which of the following is the correct term for a constraint that maintains a specific angle
between two lines in a 2D sketch?
A. Coincident
B. Parallel
C. Perpendicular
D. Angular
🟢D
🔴 Explanation: An angular constraint defines a specific angle between two selected
geometric entities, such as lines or planes.
,Question 4
What is the primary function of the "extrude" command in 3D modeling?
A. To revolve a 2D profile around an axis
B. To add depth to a 2D profile
C. To create a mirrored copy of a feature
D. To create a pattern of features
🟢B
🔴 Explanation: The extrude command adds a defined depth to a closed 2D sketch profile,
creating a solid or surface feature.
Question 5
A design professional must ensure that their drawings are compliant with international
standards. Which organization is primarily responsible for developing global standards
for technical product documentation?
A. ANSI
B. ISO
C. IEEE
D. ASME
🟢B
🔴 Explanation: The International Organization for Standardization (ISO) develops and
publishes international standards for many industries, including technical product
documentation.
Question 6
What is the "scale" of a drawing primarily used to represent?
A. The size of the paper it is printed on
B. The ratio between the drawing's dimensions and the actual object's dimensions
C. The thickness of the lines used
D. The level of detail shown
🟢B
🔴 Explanation: The scale of a drawing defines the proportional relationship between the
dimensions on the drawing and the actual dimensions of the physical object.
Question 7
Which of the following actions would be considered a violation of professional ethics in
CAD?
A. Using a software tool for a project that exceeds its capabilities
B. Sharing a proprietary design file with a competitor without authorization
C. Using a company template for a personal project
D. Accepting feedback from a colleague on a design
🟢B
, 🔴 Explanation: Sharing proprietary or confidential design information without
authorization is a serious breach of ethics and legal obligations, potentially violating non-
disclosure agreements.
Question 8
What is the purpose of a "parting line" in a design intended for injection molding?
A. To indicate a decorative feature
B. To denote a structural rib
C. To define where the two halves of the mold separate
D. To show the location of a gate
🟢C
🔴 Explanation: The parting line is a critical feature that represents the interface between
the two main halves of an injection mold.
Question 9
In the context of assembly modeling, what does the term "exploded view" refer to?
A. A view showing all components hidden
B. A view with components separated to show their relationship
C. A view with only the outer shell visible
D. A view where parts are randomly scattered
🟢B
🔴 Explanation: An exploded view systematically displaces components from their
assembly position to clearly illustrate the structure, order of assembly, and relationship
between parts.
Question 10
Which command is used to create a solid model by rotating a 2D profile around a
central axis?
A. Extrude
B. Sweep
C. Revolve
D. Loft
🟢C
🔴 Explanation: The Revolve command rotates a closed sketch profile or planar face
around a selected axis to generate a solid or surface.
Question 11
A design requires a hole to be drilled through a part. What is the best method to
represent this in a 2D drawing to minimize confusion and ensure clarity?
A. Show only the top view of the circle
B. Include a detailed section view
