Question 1Architectural and technical drawing: coordinated plans, sections and geometry

In first-angle orthographic projection (the European/ISO convention used in Cyprus technical drawing), where is the top view (plan) placed relative to the front elevation?

  1. Directly above the front elevation
  2. To the left of the front elevation
  3. To the right of the front elevation
  4. Directly below the front elevation Correct answer.

Explanation

In first-angle projection the object sits between the observer and the projection plane. After the horizontal plane is unfolded downward about the ground line, the plan appears directly below the front elevation.

Question 2Architectural and technical drawing: coordinated plans, sections and geometry

Orthographic projection is best defined as a projection system in which the projectors from the object to the picture plane are:

  1. At 30° and 60° to the picture plane
  2. Parallel to the picture plane
  3. Perpendicular to the picture plane Correct answer.
  4. Converging to a single vanishing point

Explanation

Orthographic (orthogonal) projection uses projectors that are mutually parallel and perpendicular to the picture plane, so true lengths and angles are preserved on faces parallel to that plane.

Question 3Architectural and technical drawing: coordinated plans, sections and geometry

In first-angle projection, the view obtained by looking at the right-hand side of the object is placed:

  1. Below the plan view only
  2. To the left of the front view Correct answer.
  3. To the right of the front view
  4. Above the front view

Explanation

In first-angle layout the right-side view is drawn to the left of the front view because the vertical side plane unfolds away from the object in that direction.

Question 4Architectural and technical drawing: coordinated plans, sections and geometry

Which statement correctly distinguishes orthographic views from a perspective drawing of the same building?

  1. Orthographic views keep faces parallel to the picture plane at true scale; perspective foreshortens them toward vanishing points Correct answer.
  2. Orthographic views always show the building smaller than perspective
  3. Perspective drawings never show vertical edges
  4. Orthographic views require three vanishing points

Explanation

Orthographic elevations and plans measure true lengths on faces parallel to the sheet. Perspective intentionally foreshortens edges toward vanishing points to mimic binocular vision.

Question 5Architectural and technical drawing: coordinated plans, sections and geometry

When three principal orthographic views of a rectangular prism are drawn, which pair of dimensions is shared between the front elevation and the plan?

  1. Depth only
  2. Height only
  3. Diagonal space diagonal only
  4. Width (horizontal extent of the front face) Correct answer.

Explanation

The front elevation and plan share the object's width along the shared horizontal folding line. Height appears only in elevations; depth appears in plan and side views.

Question 6Architectural and technical drawing: coordinated plans, sections and geometry

A multi-view orthographic drawing of a building typically includes which combination of principal views?

  1. Only a one-point perspective
  2. Only a freehand sketch without projection rules
  3. Plan (top), front elevation, and at least one side elevation or section as required Correct answer.
  4. Only a single isometric view

Explanation

Architectural orthographic sets use coordinated plans, elevations and sections so every critical face and cut can be measured. Isometric or perspective sheets may accompany them but do not replace the measurable orthographic set.

Question 7Architectural and technical drawing: coordinated plans, sections and geometry

If the front elevation of an object is drawn and the plan is then projected using first-angle construction, projector lines between corresponding points should be:

  1. Converging to a horizon line
  2. Perpendicular to the shared fold (ground) line between the two views Correct answer.
  3. Drawn freehand without alignment
  4. Always at 45° to the ground line

Explanation

Corresponding points in adjacent orthographic views are linked by projectors perpendicular to the fold line so widths align exactly between plan and elevation.

Question 8Architectural and technical drawing: coordinated plans, sections and geometry

An auxiliary orthographic view is used when:

  1. A face is inclined to the principal planes and its true shape is needed Correct answer.
  2. The drawing must be coloured
  3. Only furniture layout is required
  4. The sheet size must be reduced

Explanation

Auxiliary views are projected onto a plane parallel to an inclined face so that face appears in true shape and size-information the principal views foreshorten.

Question 9Architectural and technical drawing: coordinated plans, sections and geometry

In an orthographic elevation of a building, surfaces that are perpendicular to the picture plane appear as:

  1. True-shape rectangles always
  2. Circles of true diameter always
  3. Perspective vanishing lines
  4. Edges (lines) or points of zero area on that elevation Correct answer.

Explanation

A surface perpendicular to the elevation plane is edge-on to the viewer, so it projects as a line (or a point if it is an edge viewed end-on), not as an area of true shape.

Question 10Architectural and technical drawing: coordinated plans, sections and geometry

Which projection method produces a pictorial view with three axes equally foreshortened at 120° in the plane of the paper?

  1. One-point perspective
  2. Oblique cavalier with full depth only
  3. Isometric projection Correct answer.
  4. First-angle orthographic multi-view only

Explanation

Isometric projection places the three principal axes 120° apart in the drawing, with equal foreshortening along each axis, giving a measurable pictorial image.

Question 11Architectural and technical drawing: coordinated plans, sections and geometry

When transferring a length from the plan to a side elevation in first-angle construction using a mitre (45°) line, the mitre line is used to:

  1. Erase hidden lines
  2. Convert depth dimensions between plan and side view while keeping projectors orthogonal to fold lines Correct answer.
  3. Create perspective vanishing points
  4. Change the drawing scale automatically

Explanation

A 45° mitre between plan and side-view regions redirects depth projectors so the same depth dimension appears correctly in both views without measuring twice.

Question 12Architectural and technical drawing: coordinated plans, sections and geometry

A glass-box analogy for orthographic projection assumes the object is enclosed in a transparent box and each view is:

  1. Projected onto a face of the box, which is then unfolded into one plane Correct answer.
  2. Photographed with a wide-angle lens
  3. Drawn only as freehand cartoons
  4. Scaled randomly on each face

Explanation

The glass-box model explains multi-view orthographics: each principal face of the box receives one view, then the box is unfolded so all views lie on a single sheet with consistent alignment.

Question 13Architectural and technical drawing: coordinated plans, sections and geometry

If a cylindrical column is shown in plan as a circle, its front orthographic elevation (axis vertical) appears as a:

  1. Circle of the same diameter
  2. Ellipse always
  3. Triangle
  4. Rectangle whose width equals the circle's diameter Correct answer.

Explanation

A vertical cylinder projects to a circle in plan. In a front elevation looking horizontally, the silhouette is a rectangle whose width is the diameter and whose height is the column height.

Question 14Architectural and technical drawing: coordinated plans, sections and geometry

Hidden edges in an orthographic view are conventionally drawn so that they:

  1. Indicate only electrical circuits
  2. Mark the title block boundary
  3. Show geometry that exists but is not visible from that viewing direction Correct answer.
  4. Replace all centre lines

Explanation

Dashed hidden lines communicate edges and intersections that belong to the object but are obscured from the chosen viewpoint, completing the geometric description.

Question 15Architectural and technical drawing: coordinated plans, sections and geometry

An orthographic section differs from an external elevation primarily because a section:

  1. Must be drawn freehand only
  2. Shows the building as if cut by a plane, revealing interior construction Correct answer.
  3. Always uses a larger sheet
  4. Never includes dimensions

Explanation

A section is an orthographic view generated after an imaginary cutting plane removes part of the building, exposing interiors, floor build-ups and structural thicknesses that elevations hide.

Question 16Architectural and technical drawing: coordinated plans, sections and geometry

In coordinated orthographic building drawings, a vertical line in the front elevation that aligns with a corresponding line in the plan represents:

  1. The same vertical edge or wall plane projected into both views Correct answer.
  2. An arbitrary decoration unrelated to geometry
  3. A perspective vanishing ray
  4. A change of scale between views

Explanation

Alignment of corresponding edges across fold lines is the core of multi-view orthographics: one physical edge appears as linked lines in adjacent views.

Question 17Architectural and technical drawing: coordinated plans, sections and geometry

Which statement about third-angle versus first-angle projection is correct for Cyprus technical-school architectural practice?

  1. Third-angle is mandatory and first-angle is banned worldwide
  2. Both systems place all views in identical positions
  3. Projection angle only affects colour, not view placement
  4. First-angle (European/ISO) layout is the expected convention; third-angle places the plan above the front view Correct answer.

Explanation

Cyprus technical drawing follows the European first-angle arrangement. Third-angle (common in North America) places the plan above the front elevation-the reverse of first-angle.

Question 18Architectural and technical drawing: coordinated plans, sections and geometry

On a working drawing, the scale notation 1:50 means that:

  1. 1 mm on paper represents 50 mm in reality Correct answer.
  2. 50 mm on paper represents 1 mm in reality
  3. The drawing is half the size of 1:25
  4. Dimensions may be omitted because the scale replaces them

Explanation

Scale 1:50 means one unit on the drawing corresponds to fifty of the same units on the real building, so 1 mm on paper is 50 mm in reality.

Question 19Architectural and technical drawing: coordinated plans, sections and geometry

Which scale is most commonly appropriate for a detailed floor plan of a single dwelling intended for construction reading?

  1. 1:10000
  2. 1:50 Correct answer.
  3. 1:5000
  4. 1:1 only

Explanation

1:50 is a standard architectural floor-plan scale for houses: rooms, wall thicknesses and openings remain readable while still fitting a typical sheet. Much smaller scales suit site or urban maps.

Question 20Architectural and technical drawing: coordinated plans, sections and geometry

On a plan drawn at 1:100, a wall measures 45 mm on the paper. The real wall length is:

  1. 4.5 m Correct answer.
  2. 0.45 m
  3. 45 m
  4. 450 m

Explanation

Real length = drawn length × scale factor. 45 mm × 100 = 4500 mm = 4.5 m.

Question 21Architectural and technical drawing: coordinated plans, sections and geometry

Which scale is typically chosen for large-scale construction details of a window sill, stair tread build-up, or wall junction?

  1. 1:500 only
  2. 1:2000 only
  3. 1:10000 only
  4. 1:5, 1:10 or 1:20 Correct answer.

Explanation

Detail drawings enlarge critical junctions so thicknesses, flashings and fixings are readable-commonly 1:5 to 1:20. Tiny map scales cannot show construction assemblies.

Question 22Architectural and technical drawing: coordinated plans, sections and geometry

A site plan showing a house on its plot with neighbouring context is most often drawn at approximately:

  1. 1:5
  2. 1:10 only
  3. 1:200 or 1:500 Correct answer.
  4. 1:1

Explanation

Site plans need a smaller scale than floor plans so the whole plot, setbacks and access fit the sheet-commonly around 1:200 or 1:500 depending on plot size.

Question 23Architectural and technical drawing: coordinated plans, sections and geometry

If a door opening is 900 mm wide in reality and must be drawn at 1:50, the width on the paper should be:

  1. 90 mm
  2. 18 mm Correct answer.
  3. 9 mm
  4. 45 mm

Explanation

Drawn size = real size ÷ 50. 900 mm ÷ 50 = 18 mm on the sheet.

Question 24Architectural and technical drawing: coordinated plans, sections and geometry

A graphic (bar) scale on an architectural sheet is useful primarily because it:

  1. Remains usable after the drawing is enlarged or reduced in reproduction Correct answer.
  2. Replaces the need for any numerical dimensions
  3. Only works on isometric drawings
  4. Changes the representative fraction automatically

Explanation

A drawn bar scale shrinks or enlarges with the sheet when photocopied or printed at a non-original size, so approximate measuring remains possible even if the stated RF no longer matches the print.

Question 25Architectural and technical drawing: coordinated plans, sections and geometry

Which statement about stating scales on architectural drawings is correct?

  1. One unstated scale always applies to every sketch forever
  2. Scales are optional when using CAD
  3. Only perspectives need scale notes
  4. Each view or detail must show its scale if scales differ on the sheet Correct answer.

Explanation

Sheets often mix a 1:50 plan with 1:10 details. Each view or detail call-out must declare its own scale so readers do not mis-measure.

Question 26Architectural and technical drawing: coordinated plans, sections and geometry

Choosing too small a scale for a stair detail is problematic mainly because:

  1. First-angle projection stops working
  2. Critical tread, riser and nosing dimensions become unreadable Correct answer.
  3. The stair will be stronger in reality
  4. Hidden lines become unnecessary

Explanation

Stairs need clear tread/riser geometry and often handrail fixings. An undersized scale collapses those dimensions into marks that cannot be built from accurately.

Question 27Architectural and technical drawing: coordinated plans, sections and geometry

A representative fraction of 1:1 indicates:

  1. Full size - drawing lengths equal real lengths Correct answer.
  2. Half size
  3. One hundredth of real size
  4. An undefined artistic scale

Explanation

RF 1:1 means the drawing is full size: each millimetre on paper equals one millimetre on the object, typical for some manufacturing or full-size templates.

Question 28Architectural and technical drawing: coordinated plans, sections and geometry

When converting a dimension from a 1:50 drawing to a 1:100 presentation of the same plan, linear sizes on paper become:

  1. Twice as large
  2. Unchanged
  3. Four times as large
  4. Half as large Correct answer.

Explanation

Moving from 1:50 to 1:100 doubles the reduction factor, so every paper length halves while real lengths stay the same.

Question 29Architectural and technical drawing: coordinated plans, sections and geometry

Metric architectural drawings in Cyprus technical practice most commonly express building dimensions in:

  1. Fathoms only
  2. Light-years
  3. Millimetres or metres as appropriate to the drawing type Correct answer.
  4. Inches only

Explanation

Cyprus technical education uses the metric system. Plans and details typically dimension in millimetres; larger site distances may appear in metres.

Question 30Architectural and technical drawing: coordinated plans, sections and geometry

A wall thickness of 200 mm drawn at 1:50 should measure how much on the sheet?

  1. 20 mm
  2. 4 mm Correct answer.
  3. 2 mm
  4. 10 mm

Explanation

200 ÷ 50 = 4 mm on paper-thick enough to read at 1:50, which is one reason that scale suits dwelling plans.

Question 31Architectural and technical drawing: coordinated plans, sections and geometry

Which scale statement is written correctly for an architectural detail?

  1. Scale 1:10 Correct answer.
  2. Scale 10:1 enlargement without context when it is actually a reduction
  3. Approx big
  4. NTS used while still expecting exact take-offs from the print without notes

Explanation

Standard practice states the representative fraction clearly (e.g., Scale 1:10). Ambiguous phrases and misuse of NTS (not to scale) undermine reliable measurement.

Question 32Architectural and technical drawing: coordinated plans, sections and geometry

If an area on a plan is measured with a planimeter or by counting squares, changing the drawing scale from 1:100 to 1:50 multiplies true area interpretation factors because area scales with the:

  1. Cube of the linear scale factor
  2. Same factor as length only
  3. Inverse of sheet weight
  4. Square of the linear scale factor Correct answer.

Explanation

Linear RF scales lengths; areas scale with the square of that factor. Halving the linear reduction (1:100 → 1:50) multiplies paper areas by four for the same real region.

Question 33Architectural and technical drawing: coordinated plans, sections and geometry

On architectural drawings, visible outlines of walls and other solid edges are conventionally drawn with:

  1. Dimension lines only
  2. Freehand cloudy revision clouds only
  3. Continuous thick lines Correct answer.
  4. Chain thin centre lines

Explanation

Line hierarchy assigns continuous thick lines to primary visible outlines so the building fabric reads first. Thinner lines carry dimensions, hatching and minor detail.

Question 34Architectural and technical drawing: coordinated plans, sections and geometry

Hidden edges that exist but cannot be seen from the viewing direction are usually shown as:

  1. Double chain dimension lines
  2. Dashed (broken) lines Correct answer.
  3. Continuous thick outlines
  4. Solid filled black bands only

Explanation

Short dashed lines are the standard hidden-edge convention, allowing incomplete silhouettes to still communicate obscured geometry.

Question 35Architectural and technical drawing: coordinated plans, sections and geometry

Centre lines and axes of symmetry on technical drawings are typically drawn as:

  1. Long-dash short-dash (chain) thin lines Correct answer.
  2. Continuous thick outlines
  3. Solid red ink only by rule
  4. Zigzag break lines

Explanation

Chain (centre) lines identify axes and centres of circles or symmetrical features without being mistaken for object outlines.

Question 36Architectural and technical drawing: coordinated plans, sections and geometry

In a floor plan, a door is commonly symbolised by a door leaf in open position together with:

  1. A north arrow drawn on the leaf
  2. A section marker through the handle only
  3. A graphic scale bar on the leaf
  4. An arc showing the swing direction Correct answer.

Explanation

The quarter-circle (or similar) swing arc shows which way the door opens and how much clearance it needs-critical for furniture layout and escape paths.

Question 37Architectural and technical drawing: coordinated plans, sections and geometry

Window symbols on plans typically indicate glazing within the wall thickness using:

  1. A grid bubble only
  2. A title-block stamp
  3. Thin parallel lines or a conventional glazed break in the wall hatching Correct answer.
  4. A stair arrow

Explanation

Plan window symbols interrupt the wall and show the glazed unit with simplified parallel lines or a standard window break so openings are counted and located correctly.

Question 38Architectural and technical drawing: coordinated plans, sections and geometry

Material hatching in a section through reinforced concrete is commonly represented by:

  1. Perspective shading only
  2. Diagonal line hatching (often ~45°) within the cut concrete profile Correct answer.
  3. A wood-grain pattern only
  4. A blank white void with no boundary

Explanation

Standard section conventions use distinctive hatching patterns so cut concrete, masonry, insulation and earth can be told apart at a glance.

Question 39Architectural and technical drawing: coordinated plans, sections and geometry

A north arrow on an architectural plan is required so that:

  1. Orientation of rooms, façades and solar exposure can be understood Correct answer.
  2. The scale becomes 1:1
  3. Hidden lines become continuous
  4. First-angle projection is converted to third-angle

Explanation

Plans are oriented for readability, not always with north up. The north arrow restores geographic orientation for climate, views and site relationships.

Question 40Architectural and technical drawing: coordinated plans, sections and geometry

Section cutting-plane lines on plans are usually marked with thickened ends and arrows that:

  1. Show the swing of doors only
  2. Replace dimension terminators
  3. Indicate only underground services
  4. Indicate the direction of view looking at the section Correct answer.

Explanation

Cutting-plane symbols locate where the building is cut and which way the section is viewed, so the section drawing can be matched to the plan.

Question 41Architectural and technical drawing: coordinated plans, sections and geometry

Break lines that shorten a long uniform object on a drawing are typically drawn as:

  1. Dimension extension lines
  2. Title underlining
  3. Thin freehand or zigzag lines interrupting the object Correct answer.
  4. Continuous thick outlines through the whole length only

Explanation

Break lines allow a long beam, wall or pipe to be shown shortened while signalling that material continues-saving sheet space without implying a real joint.

Question 42Architectural and technical drawing: coordinated plans, sections and geometry

Grid lines and bubbles on architectural drawings primarily serve to:

  1. Show only electrical wattage
  2. Locate structural bays and reference positions across plans and elevations Correct answer.
  3. Indicate paint colours only
  4. Replace stair numbering

Explanation

Alphanumeric grids provide a common coordinate language so columns, walls and openings can be referenced consistently between drawings and on site.

Question 43Architectural and technical drawing: coordinated plans, sections and geometry

Level symbols (spot heights / FFLs) on plans and sections communicate:

  1. Vertical elevations of floors or ground relative to a stated datum Correct answer.
  2. Only the drawing sheet number
  3. Door fire ratings exclusively
  4. The exam duration

Explanation

Finished floor levels and spot heights tie the project to a datum so storeys, thresholds and external ground relate correctly in three dimensions.

Question 44Architectural and technical drawing: coordinated plans, sections and geometry

Insulation in section is often indicated by a conventional pattern resembling:

  1. A north arrow
  2. A door swing arc
  3. A title block logo
  4. A continuous batt/blob or staggered rectangle pattern within the insulated cavity Correct answer.

Explanation

Distinct insulation hatching (or CAD patterned fills) identifies thermal layers inside walls, roofs and floors so build-ups can be read quickly.

Question 45Architectural and technical drawing: coordinated plans, sections and geometry

Revision clouds and revision triangles/numbers are used to:

  1. Set the printed scale automatically
  2. Mark only demolished buildings in every case
  3. Highlight areas changed since a previous issue of the drawing Correct answer.
  4. Indicate first-angle projection

Explanation

Revision graphics call attention to what changed between issues so contractors and examiners of record can track updates. Demolition has its own dashed/existing conventions.

Question 46Architectural and technical drawing: coordinated plans, sections and geometry

A typical title block on an architectural sheet should include at least:

  1. Only an isometric thumbnail without identifiers
  2. Project name, drawing title, scale(s), date, and drawing/sheet number Correct answer.
  3. Only a decorative border with no text
  4. Only the student's favourite colour

Explanation

Title blocks identify the sheet uniquely and state critical metadata (scales, dates, revisions) needed to manage a drawing set.

Question 47Architectural and technical drawing: coordinated plans, sections and geometry

Existing construction to be demolished is commonly shown with:

  1. Dashed or screened existing lines, often with demolition notes Correct answer.
  2. Thicker new-work outlines only without distinction
  3. Perspective colour washes only
  4. Removing all levels from the sheet

Explanation

Demolition conventions distinguish what stays from what is removed-typically dashed/screened existing fabric plus clear notes-so contractors do not strip the wrong elements.

Question 48Architectural and technical drawing: coordinated plans, sections and geometry

Match lines on large plans that cannot fit on one sheet indicate:

  1. The position of the north arrow only
  2. A change from first-angle to third-angle mid-sheet
  3. That dimensions are not to scale everywhere without a note
  4. Where the drawing continues on an adjacent sheet Correct answer.

Explanation

Match lines and key plans tell the reader how tiled sheets join so a large floor plate can be read across multiple pages without geometric gaps.

Question 49Architectural and technical drawing: coordinated plans, sections and geometry

Timber in section is often suggested by hatching that resembles:

  1. A stair riser arrow
  2. Electrical outlet circles
  3. End-grain rings or longitudinal grain lines depending on cut direction Correct answer.
  4. Concrete 45° diagonals only

Explanation

Wood conventions vary by whether the cut is across the grain (end grain) or along the grain (longitudinal lines), helping readers distinguish timber members from masonry or concrete.

Question 50Architectural and technical drawing: coordinated plans, sections and geometry

A building section is produced by:

  1. Rotating a perspective until it becomes flat
  2. Cutting the building with an imaginary plane and drawing the resulting orthographic view Correct answer.
  3. Photographing only the street façade
  4. Listing materials without a drawing

Explanation

Sections are orthographic views after a cutting plane removes part of the building, revealing interior heights, floor structures and construction thicknesses.
