Question 1
Which statement about extension lines in dimensioning is true?
Correct Answer:
Extension lines should not touch dimension lines
Explanation:
Extension lines are the thin lines that connect a feature’s boundary to the dimension line, showing how far the measurement applies. They should extend from the object but stop short of the dimension line, leaving a small gap so the dimension line remains clear and separate. This separation prevents the lines from visually blending and helps readers identify exactly what is being measured. Extension lines are drawn as continuous, thin lines, not dashed, and they are not thicker than the dimension line. So the statement that extension lines should not touch the dimension lines is the correct practice, because keeping a small gap preserves clarity and avoids ambiguity in reading the dimensions.
Question 2
What is the recommended countertop height relative to drawer tops or doors, including tolerance?
Correct Answer:
A height of 1/4 inch, with a tolerance of 1/8 inch above draw tops or doors.
Explanation:
The countertop should sit about a quarter inch higher than the tops of the drawers or doors, with a small allowance so you can go up to an eighth inch higher. This slight offset creates a clean, even reveal along the cabinet fronts and helps prevent gaps or misalignment when you install the countertop. The tolerance gives you room to account for small variations in cabinet face heights, levelness, or material changes without breaking the overall look.
Question 3
Why is it preferable to apply finishes before assembly?
Correct Answer:
Allows for equal sealing of all surfaces.
Explanation:
Sealing all surfaces evenly is the main idea. Finishing components before assembly lets you coat every face, edge, and end grain before anything is joined, so the entire piece gets a uniform film. End grain tends to absorb finish more, and areas that will be inside joints or behind hardware can be hard or impossible to reach after assembly; by pre-finishing, those surfaces are protected and leakage or uneven absorption is avoided. When parts are later put together, you don’t risk exposed or underscored areas that would show up as blotching, uneven color, or thin spots at seams. Finishing before assembly thus delivers a more consistent, durable seal across all surfaces, which is harder to achieve if you wait until after assembly.
Question 4
For circular handrails, the diameter may not be less than what inch and may not be more than what inch in diameter?
Correct Answer:
1 1/4 inch to 2 inch
Explanation:
Circular handrails must be sized so a hand can comfortably wrap around and grasp them, ensuring a secure grip during use. The diameter range that supports this grip is from 1 1/4 inches to 2 inches. If the rail is smaller than 1 1/4 inch, it’s too slender to grip firmly; if it’s larger than 2 inches, fingers can’t wrap around it effectively, making it harder to hold onto. This balance helps promote safety and consistency in handrail design.
Question 5
In some cases, it might be unwise to use plastic wrap on new cabinets. Why?
Correct Answer:
Some natural finishes can be affected by direct contact with plastic sheets.
Explanation:
Direct contact with plastic wrap can affect some natural finishes because those finishes are more sensitive to moisture, solvents, and chemicals that can migrate from the plastic. When a new cabinet surface is covered directly with plastic, trapped moisture and any plasticizers or additives can interact with the finish or slow its curing. This can lead to issues such as hazing, staining, soft spots, or improper adhesion. Not all finishes react the same way—many durable film finishes resist contact, but natural finishes like waxes, shellac, or oil-based coatings can be damaged or altered by direct plastic contact. To avoid these problems, let the finish cure without direct coverage or use a breathable barrier if you must protect the surface.
