MArch Master of Architecture Master of Architecture: Architectural Design And Drafting 2 — Questions and Answers
Question 1: In architectural working drawings, what does a dashed line typically represent?
- A visible edge of a wall
- A hidden or concealed element (Correct answer)
- A section cut line
- A property boundary
Correct answer: A hidden or concealed element
Dashed lines in architectural drawings indicate elements that are hidden from the current view, such as features above or below the cut plane.
Question 2: Which drawing type shows the interior of a building as if it were cut horizontally at approximately 4 feet above the floor?
- Section drawing
- Floor plan (Correct answer)
- Reflected ceiling plan
- Site plan
Correct answer: Floor plan
A floor plan is created by slicing the building horizontally at roughly 4 feet (1.2 m) above the floor level to reveal the layout of walls, doors, and windows.
Question 3: What is the primary purpose of a reflected ceiling plan (RCP) in construction documents?
- To show foundation depths
- To document lighting, HVAC, and ceiling features as viewed from above (Correct answer)
- To illustrate the roof slope and drainage
- To detail exterior cladding materials
Correct answer: To document lighting, HVAC, and ceiling features as viewed from above
An RCP shows ceiling-mounted elements such as light fixtures, diffusers, and ceiling finishes as if reflected onto a mirror on the floor, viewed from above.
Question 4: In the Design-Build project delivery method, who holds the contract with the owner?
- Architect only
- General contractor only
- A single entity responsible for both design and construction (Correct answer)
- The structural engineer
Correct answer: A single entity responsible for both design and construction
In Design-Build, a single entity (which may be a design-build firm or a contractor-led team) holds the contract with the owner for both design and construction services.
Question 5: What drafting convention is used to indicate a material break or a continuation of a long element on a drawing?
- Zigzag or break line (Correct answer)
- Center line
- Extension line
- Leader line
Correct answer: Zigzag or break line
A break line (shown as a freehand zigzag or 'S' curve) indicates that a portion of the drawn object has been omitted for space economy while the element continues.
Question 6: In AutoCAD-based architectural drafting, what does the term 'xref' (external reference) allow a drafter to do?
- Export a file to PDF format
- Attach another drawing file as an underlay without permanently merging it (Correct answer)
- Convert 2D drawings into 3D models automatically
- Apply hatch patterns across multiple layers simultaneously
Correct answer: Attach another drawing file as an underlay without permanently merging it
An xref links an external drawing file so it displays as an underlay; changes to the referenced file update automatically in the host drawing without merging the data.
Question 7: Which scale would be most appropriate for drawing a detailed wall section in US architectural practice?
- 1" = 100'
- 1" = 20'
- 1" = 1' (Correct answer)
- 3" = 1'-0"
Correct answer: 1" = 1'
A 1" = 1'-0" scale (or 1:12) is commonly used for wall sections, allowing enough detail to clearly show assembly layers, insulation, and material thickness.
