1.When a designer or an ordinary person translates his or her own design idea with the use of paper and pencil, what is the name of the activity?

A. Architectural delineation
B.Freehand Sketching
C.Geometric Construction
D.Drafting

 Answer: B. Freehand sketching

Freehand sketching- is when you use any sort of utensil to make marks without the use and/or aid of guides such as rulers, straight edges, or  even projectors and other tracing or reproduction element 

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
C. Specifications
D. Sectional Drawing

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


3.With the help of drawing instruments such as T-square and triangles, one produces quick and accurate delineations for an intended project. The process is considered as:
A. Drafting
B. Pictorial Drawing
C. Graphics
D. Shape and Size Descriptions

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
C. Line Weight
D. Measurement

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.


5. Objects to be drawn are not always solid in nature and if we want to explain complex objects to the reader of our blueprints we need an imaginary cut through the component or an assembly drawing to portray exactly what is inside. This element is called:
A. Sectioning
B. Parallel Perspective
C. Etching
D. Dimensioning

Answer: A. Sectioning

Sectioning- the process of sketching the internal configuration of an object by showing it cut apart is known as sectioning. Sectioning is used frequently on a wide variety of Industrial drawings.

Parallel Perspective-  linear perspective in which parallel lines of the object that are perpendicular to the drawing surface are represented as meeting at a point on the horizon in line with the common point of intersection of the lines of projection— called also one-point perspective.

Etching-  is an intaglio printmaking process in which lines or areas are incised using acid into a metal plate in order to hold the ink.

Dimensioning- the process of adding size information to a drawing is known as dimensioning the drawing.

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
C. Drawing of views
D. Legibility

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

Legibility- is mostly a function of typeface design. It's a measure of how easy it is to recognize one letter or word from another and how easy blocks of text are to read. | the quality of being clear enough to read..

7. In various engineering fields, multiple line weights are being to emphasize areas of drawing. It is also standardized in order for a uniform interpretation drawing. The term is called:
A. Horizontal Line
B. Center line
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.

8.It is about placing units of measure to the height, width, and length of an object to convey accurate instructions to part. In old English it is called “dimensions”. In drafting this means:
A. Tolerance
B. Datum
C. Axis
D. Dimensioning

 Answer: D. Dimensioning

Dimensioning- the process of adding size information to a drawing is known as dimensioning the drawing.

Tolerance- the difference between the acceptable maximum and minimum dimensions given for a hole, shaft, or other feature is known as the tolerance.

Datum- is a plane, a straight line, or a point that is used as a reference when processing a material or measuring the dimensions of a target.

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
B. Perspective Construction
C. Isometric Drawing
D. Fourth Dimension

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.

10. .Which technique in pictorial drawing appears like 3-dimensional but the lines are exactly 30 degrees from horizontal part of the object?
A. Isometric Drawing
B. Cabinet Drawing
C. Oblique Drawing
D. Perspective Drawing

Answer: A. Isometric Drawing

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.

Cabinet Drawing- an oblique projection in mechanical drawing in which dimensions parallel to the third axis of the object are shortened one half to overcome apparent distortion.

Oblique Drawing- is a type of projective drawing in which the frontal lines are given in true proportions and relations and all others at suitable angles other than 90 degree without thinking about the rules of linear perspective.

Perspective Drawing- is what gives a three-dimensional feeling to a flat image such as a drawing or a painting. In art, it is a system of representing the way that objects appear to get smaller and closer together the farther away they are from the viewer.
