Architectural Delineation- is used to refer to the method architects uses to present their work to potential clients, partners or even just the general public that aren’t involved in the technical part of the process.
Geometric Construction- the process of drawing lines, angles, and other geometric shapes and figures using only a compass and a straightedge
Drafting- drawings done by technical men and skilled industrial workers which are also freehand drawings but are shown in a special type of drawing called orthographic projection. Generally, an object is shown in three orthographic views—top, front, and side views.
2.After two dimensional drawings are done and all the shapes and sizes being laid-out, the next step to be executed to complete the process is_.
A. Dimensioning
B. Tolerancing
Answer: A. Dimensioning
Dimensioning- is the process of measuring the sizes of parts and overall sizes of assemblies are conveyed by dimensions placed on the drawing.
Tolerancing- is the process the total amount a dimension. may vary and is the difference between the upper (maximum) and lower (minimum) limits.
Specifications- drawing notes that describe materials, equipment, systems, standards, or workmanship are specifications
Sectional Drawing- shows a view of a structure as though it had been sliced in half or cut along another imaginary plane

A. Drafting
B. Pictorial Drawing
Answer: A. Drafting
Drafting- in drafting a draftsman in making drawings use mechanical drawing tools commonly used in mechanical drawings such as dividers, drawing boards, pencils, scales, triangles and t- squares.
Pictorial Drawing- view of an object (actual or imagined) as it would be seen by an observer who looks at the object either in a chosen direction or from a selected point of view.
Graphics- is the making of architectural or design drawings.
Shape and Size Descriptions- is the shapes of all the parts and their interrelation are exactly described by the representation of that information in the set of drawings
4. Technical drafting involves the manipulation of the elements of geometry to make accurate description of shapes. Which term is referred to by engineering’s and drafting professionals all over world?
A. Blueprint Reading
B. Geometric Construction
Answer: B. Geometric Construction
Geometric Construction- refers to the process of drawing lines, angles, and other geometric shapes and figures using only a compass and a straightedge
Blueprint Reading- are 2-dimensional architectural design drawings that indicate the size of a planned building,
Line Weight- is the light or darkness and width of a line.
Measurement- the process of associating numbers with physical quantities and phenomena.

6. To make drawings look more professional, the notes, dimensions, and other specifications must be professionally executed. In manual drafting this is called:
A. Lettering by the hand
B. Scaling
Answer: A. Lettering by the hand
Lettering by the hand- is the process of forming letters, numerals, and other characters in technical drawing. It is used to describe, or provide detailed specifications for, an object. With the goals of legibility and uniformity, styles are standardized and lettering ability has little relationship to normal writing ability.
Scaling- is a drawing method used to enlarge or reduce a drawing in size while keeping the proportions of the drawing the same.
Drawing of views- basically drawing of different views, Front, Rear, Side View

C. Alphabet lines
D. Dimensioning
Answer: C. Alphabet of lines
Alphabet of lines- use of line symbols enables engineers/designers to express the features of designed products clearly and accurately. Line features vary not only by width but also by how they are graphically represented in a drawing.
Horizontal Line- is a straight line that is drawn from left to right or right to left and it is parallel to the x-axis in the coordinate plane.
Center line- a real or imaginary line that is equidistant from the surface or sides of something.
Dimensioning- the process of adding size information to a drawing is known as dimensioning the drawing.

Axis- is a line that runs straight through something in order to show the direction and movement of something.
9. Which is a method of representing the exact shape and size of an object drawn to scale on “set of planes” which sometimes are called planes of projection? It is also known as 3-view drawing.
A. Orthographic Projection
Answer: A. Orthographic Projection
Orthographic Projection- drawings occur in multi-drawing sets in order to depict each side, top and bottom view. Professions in design and construction use these types of drawings to inform the viewer of layout, size and shape. House floor plans illustrate a common type of orthographic drawing.
Perspective Construction- is a technique for depicting three-dimensional volumes and spatial relationships in two dimensions, as if from the view-point of an observer.
Isometric Drawing- a pictorial representation of an object in which all three dimensions are drawn at full scale rather than foreshortening them to the true projection. An isometric drawing looks like an isometric projection but all its lines parallel to the three major axes are measurable. 30 degree tilt.
Fourth Dimension- a dimension in addition to length, width, and depth, used so as to be able to employ geometrical language in discussing phenomena that depend on four variables: Time is considered a fourth dimension for locating points in space-time.

A. Engineer’s
C. Architect’s
Answer: A. Engineer’s
Engineer’s Scale- The relation between the dimension on the drawing and the actual dimension of the object is mentioned numerically (like 10 mm = 15 m). • Graphical Scale: Scale is drawn on the drawing itself.
Metric Scale- are usually based on ratios. A ratio is the relationship of one measurement to another. For example, metric plot plans are often drafted in ratios of 1:100. This scale is very close to the scale 1/8" = 1'-0" (1:96).
Architect’s Scale- such as 1/4˝ = 1´-0˝ (1/48 size) or 1/8˝ = 1´-0˝ (1/96 size), are used for structures and buildings. They are used to measure interior and exterior dimensions such as rooms, walls, doors, windows, and fire protection system details. Other scale tools include flat scales and rolling scales.

A. millimeter
B. centimeter
Answer: A. millimeter
60.These units are based on inch-foot and yard measurements:
C. U.S. customary units
D. ISO international units
Answer: C. U.S. customary units
international customary units- the seven base units were chosen for historical reasons, and were, by convention, regarded as dimensionally independent: the metre, the kilogram, the second, the ampere, the kelvin, the mole, and the candela.
U.S. metric units- the metric system is a system of measurement that uses the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass) respectively.
U.S. customary units-measure length and distances in the customary system are inches, feet, yards, and miles.
ISO international units- a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time), metre (m, length), kilogram (kg, mass), ampere (A, electric current), kelvin (K, thermodynamic temperature), mole (mol, amount of substance), and candela (cd, luminous intensity)
61.This is how axonometric, oblique, and perspective sketches show objects:
A.Orthographically
B.Pictorially
Answer: B. Pictorially
| There are three (3) types of pictorial drawing; these are the Axonometric, Oblique, and Perspective drawings. The axonometric drawing is based upon the rotation principles; these are further classified into three (3) kinds, these are Isometric, Diametric and Trimetric. The Isometric shows the axis of revolution perpendicular to the horizontal plane. In here, the drawing or the object projects or shows two faces; the objects front as well as the view in the right side. The Diametric shows or projects two faces of views; the objects' top view as well as its left side view. The Trimetric shows or projects three faces or angles; the top view, the left and the right side view. In the Oblique drawing, one face of the object is parallel in the plane of projection. Like the isometric drawing, the Oblique drawing also uses three axes. The two of these axes are placed in perpendicular to each; while the third axis is placed in any angle that is convenient to the horizontal. There are two (2) types of Oblique drawing; these are the Cavalier drawing and the Cabinet drawing. In the Cavalier drawing, the receding lines usually are at thirty (30) degrees or it is at forty five (45) degrees to the horizontal axis. In the Cabinet drawing, the object is presented as it appears to a particular position in where the observer positioned relative to the object. This drawing presentation looks like the objects actually appear to the eyes of the viewer. The Perspective Drawing represents the objects as it would actually appear to the observer from a particular place. This is also another kind of pictorial drawing in which objects are presented as they actually appear to the viewers eyes. There are different kinds of pictorial drawing; the Parallel or One-Point Perspective, the Angular or Two Point Perspective and the Three Point Perspectives.  |
