To create a clean through-hole in a 3D box (solid), can a drafter place a 3D cylinder and use a Boolean subtract operation to remove material?

Introduction / Context:
Creating holes in 3D solids is a foundational CAD task. One of the most common workflows uses Boolean operations: Union, Subtract, and Intersect. This question checks whether you recognize that subtracting a cylindrical solid from a prismatic solid yields a cylindrical void (hole).

Given Data / Assumptions:

• The box is a 3D solid.
• The cylinder is also a 3D solid that fully intersects the box where the hole is desired.
• Boolean operations are available (e.g., SUBTRACT).

Concept / Approach:
Boolean subtract removes the volume of one solid from another. If a solid cylinder passes through a solid box, subtracting the cylinder from the box creates a through-hole matching the cylinder's diameter and path.

Step-by-Step Solution:

Verification / Alternative check:
Inspect section views or use visual styles to confirm the cylindrical void. Volume/mass properties reflect removed material.

Why Other Options Are Wrong:
“Incorrect” contradicts standard solid modeling practice. “Only if the cylinder is a surface” is wrong: subtraction requires solids for solid-solid Boolean. Visual style and projection choices do not govern Boolean validity.

Common Pitfalls:
Using a surface (not a solid) for subtraction; selecting operands in wrong order; failing to ensure full intersection through the target solid.

Final Answer:
Correct
