LO1 Plan and prepare for work
Review on drafting tools, materials and equipment, their uses and care
Most architectural drafting works generally consist of freehand and
mechanical drawings. As such, the learner must know how to plan and
prepare carefully all drafting tools, materials, and equipment needed for the
required work or job.
It is presumed that all students are already aware on the tools and
materials needed in drafting works considering their prior learning in the
previous year level. However, it is necessary to review their previous learning
to prepare them for higher drafting activity.

INFORMATION SHEET 1.2
LO1. Plan and prepare for work
ARCHITECTURAL WORKING DRAWINGS
The architectural working drawings together with the specifications
are the most important parts of the documents constituting the contract.
Information on the designs, locations, and dimensions of the elements of a
building is found on the architectural working drawings while information
on the quality of materials and workmanship is found in the specifications.
A good architectural working drawing gives the contractor the exact
information he needs. It should be clear, simple, and orderly arranged, and
accurately drawn so that scaled measurements will match with dimensions.
The finished drawings made by the architect, or draftsman and used
by
the
contractor
are
called
architectural
working
drawings.
The
architectural working drawings, together with the specifications and the
general conditions, form the legal contract between the owner and the
contractor. Since the working drawings are a major portion of the contract
documents, they should be very carefully drawn.
Students will be able to interpret, identify tools and materials used in
working drawings and fully understand the standard procedure in layouting
and detailing architectural working plans and drawings.

ARCHITECTURAL WORKING DRAWINGS
After all the drawings are performed, it is also necessary to expose the
student in tracing activity. This activity is commonly applied in industry
especially in the reproduction of the architectural plans. All drafting works
must be done first in the preliminary process using sketching sheet. The
final outputs are those drawings which are done through tracing activity.
Below is a activity on tracing the drawing.
Steps in tracing architectural working drawing sheet no. # 1:
1. Prepare all tools and materials needed.
2. Fasten sheet #1 and tracing paper on drawing board. Be sure it is aligned
horizontally by the T-square and aligned vertically with the triangle.
3. Trace border lines using T-square, 300 x 600 triangle, and technical pen
point 0.8-1.0.
3. Trace all the labels in title block and index using technical pen point 0.3 –
0.6.
4. Trace first all vertical lines using big triangle 300 x 600. Follow all
horizontal lines using T-square before tracing all the curved and irregular
curved lines using French curved instrument or templates.
5. Trace all the labels and dimensions using technical pen point 0.1-0.4.

This lesson is only a review of your prior learning in technical drawing
particularly on the proper use and care of drawing tools, materials and
equipment. The purpose of this discussion is to allow the students review
and recall its importance in the Drafting Technology works.
The Importance of Drawing tools, materials and equipment
a. Drawing/Drafting tools
These refer to the sets of tools that are used in all drafting works or
activities especially if the activity requires mechanical presentation. Prior to
the start of drafting activity, it is expected therefore that all drawing tools
needed must be available in the work station to ensure that the assigned
task can be accomplished according to customers or client’s standard.
The following are the common drafting tools
1.
Drafting Table/Drawing Board (24” x 36” /0.61cm x 0.91cm)
2.
T-Square (36” /0.915 cm. length)
3.

b. Drawing/Drafting Materials
These are sets of consumable items that are specifically used in
drafting works or activities. The draftsman cannot perform his drafting task
without these items.
The following are the required materials needed in drafting works:
1. Bond Paper (short and Long)
2. Tracing paper
3. A4 drawing paper
4. Drawing pencil – HB, F, 2H
5. Mechanical pencil – point 0.3, 0.5
6. Pen and Ink Eraser
7. Masking Tape
8. Ink (Staedler/Rotring)
9. Cartolina Paper
c. Equipment
These items are also essential in producing quality drafting
output especially if the assigned task requires mechanical
manipulation. Although, these items are so expensive, however, these
are important in making the drawing output presentable and
convincing to the clients.
The following are some of the equipment needed in drafting task:
1. Drafting machine
2. Leroy Lettering Pen
3. Computer

INFORMATION SHEET 2.2
LO1. Plan and prepare for work
Procedure in Setting up Drawing tools, Materials and Equipment and
standard procedure
In preparation for a required task in drawing architectural layout and
details, a draftsman should plan, prepare, and select tools and materials for
a particular planning layout. This is to ensure the correct setting of
standard procedure and accuracy of drawing plans. Some of the key tools
used in drafting architectural plans are described and illustrated in this
learning Outcome.
The drawing tools, materials and equipment are very expensive items,
however these are important in all drafting tasks. Considering its cost and
value in drafting activity, it is also important to take care and maintain its
usability.
With this, the following considerations are strictly emphasized as
Standard Operating Procedure during and after the utilization of the drafting
tools, materials and equipment:

INFORMATION SHEET 3.1
LO3 DRAFT SITE DEVELOPMENT PLAN
SITE DEVELOPMENT PLAN is the outline and measurements of the
proposed building and its placement on the property.
This shows the position and the location of the building with
property line, setbacks, approaches, grade contours, landscape
and other pertinent data in relation to the site. A site development
plan is drawn using a scale not smaller than 1:200meters.
SITE DEVELOPMENT PLAN
44
SITE is an area of land available for construction or the lot on which a
building is constructed. Building site maybe a single lot, a series of
lots, or a subdivision. A lot is a piece of ground of specific size. A
subdivision is a large tract of land that is being developed.
PLANNING CONSIDERATION IN DEVELOPING THE SITE
 Location of a proposed house on the lot. The location of the house
must be considered in order to determine the locations of the rooms and
the house itself on the lot. Some lots are located on swampy grounds
and others on hilly or rugged terrain. Still others are sited near rivers,
highways, streets and squatter areas. The front part of the house
generally faces the street or away from ugly views like the back parts of
neighboring houses, a swampy area, and thick bushes.

Many want their bedrooms to face the sunrise – which is, on the
eastern side of the lot. Others, especially those who work at night, prefer
their bedrooms located on the west side. The breeze at the site may
determine the location of the living room and toilet or bathrooms. The
height of the flood waters in the locality should also be considered in
determining the distance of the first floor from the ground. This is
especially true in low areas. In high locations the floor may be 20 cm.
only from the ground level.

As earlier mentioned the house may be located at the center of the lot.
Or one of its sides may be exactly on a lot line or fence. In this case, a
firewall which is made of concrete, adobe, and concrete hollow blocks
should be constructed on this side of the house.
 Like and dislikes of the family member. This factor is usually
considered when the family is rich and can afford to pay for the services
of an architect or draftsman. Before he designs the house, the architect
or draftsman has to first interview the members of the family to get
information about their interests, hobbies, and the like. From such
interviews, he will get to know whether the family wants a library or
study room, a social hall, a playroom, a music room, a swimming pool, a
45
carport or garage, servant’s quarters, a driver’s room, a landscaped
garden, a balcony, and a roof garden.
Property Lines are those lines working outside of the lot area.
Setback refers to the distance at how far a building can be built within the
property lines.

Zoning refers to the legal restrictions on size, location, and type of
structures to be built on a designated area.
46
Zoning Laws
One major area covered by building code is the zoning laws. Zoning
laws are designed to keep different areas of a community from interfering
with each other. In some cities or towns, separate areas are set aside for
specific uses. Examples are residential, commercial, and industrial. These
are established and protected by zoning laws.
In addition, zoning laws establish standards for construction in
different sizes and uses.
One of the first things an architect must do before designing a
building is to read the building codes. The intended use of the building
has to be within the limits of zoning laws. Also, the size of the lot must be
large enough to meet the requirements.
Building Code are local laws that set standard for structural design within
the community.
This is a collection of local laws that regulate the building of
homes and other structures. These legal requirements are intended
to protect the safety and health of the people who live and work in the
buildings. They regulate restrictions concerning the construction of
buildings to provide safety to the occupants.
All constructions in an area must meet the requirements of
building codes. Some of the designs and construction features covered
by building codes include:




Qualifications of persons who can design building within the area.
Structural design that can be used
Lot sizes for certain types of buildings
Types and sizes of materials that can be used.
47
National Building Code Rules:
1. For one-storey wooden or frame house, the height of the floor plan
from the ground should not be less than 1.50 m.
2. Walls with window opening should not be less than 2.00 m. from the
lot line of fence. In other words, adjacent houses should not be at
least 4.00 m. from each other.
3. The front part of a house should not be less than 3.00 m. from the lot
line along the street.
4. No windows should be constructed along a wall of a house if this wall
is flush with or exactly on the lot line.

L.4. FLOOR PLAN FEATURES
Floor Plan
Floor plan is the top cross-sectional view of the floor area of a house.
The horizontal cutting plane line for this top view passes between the upper
and lower window sills or one meter above the floor line. It shows the size
and arrangement of the rooms. It also presents the sizes and locations of the
stairs, door and windows openings, and partitions and walls. Sometimes it
includes the kind of furnishings in each room. However, the materials
required for constructing permanent or integral parts of each room such as
bedroom closets, kitchen cabinets, etc., should also be accounted for in the
bill of materials.

FLOOR
PLAN
SCALE: 1:100 M.
In multi-storey buildings, a separate floor plan is drawn for each floor
level when the layout of the room is not in each floor. However, when two or
65
more floor levels have the same arrangement and features, one typical floor
plan representing all the identical floors will suffice to be drawn.
Room Requirements and pointers in planning a floor plan
1. Living Room is the center of the living area in most homes. It should
be centrally located and should be adjacent to the outside entrance
and to the dining area, but the entrance should not lead directly into
the living room. Recommended sizes should be at least 2.00m x 3.00
small, 3.7m. x 5.5m. average or optimum size would be 6.1 x 7.9 m. in
rectangular shape.
2. Bedroom is a room for sleeping and taking rest of the family. Ideal
number of rooms for low cost housing should be two bedrooms,
master’s bedroom and bedroom. Preferably, there should be a toilet
and bath in master’ bedroom and a built-in cabinets or closets.
3. Dining Area is the area where greatly depend on eating habits of the
occupants. This should be located between the living room and
kitchen.
Its size and shape are determined by the size of the family.
4. Kitchen is the place for preparation of food and connecting the work
triangle area for storage and mixing center, preparation and cleaning
center and cooking center. There should be a storage hanging kitchen
cabinet with a minimal width of 0.60 meter.
Types of Kitchen
66
1. U-shaped kitchen
67
2. . L-shaped type
3. Corridor type
68
5. Bathroom is where the toilet and tub or shower are separated to save
economically in plumbing. As much as possible keep the toilet near
69
the kitchen. The bath and toilet must be near the bedrooms,
accessible to the living room even without passing through other
rooms. The toilet and bath are generally located between bedrooms. In
a two-storey residential house, the bedrooms, toilet, and bath are
often located on the second floor. In this case, the stair must go up
from the living room or hall if there is any. The stair is generally L or
U-shaped and has a landing.
Bathroom Doors and Windows Bathroom door could be small as 5560 cm. except for utility bathroom which requires not less than 70.cm.
wide to allow passage of equipment as required. In general, bathroom
wall contain only one door.
6. Entrances Entrance is divided into several different types; the main
entrance, the service entrance, and the special- purpose entrance. The
entrance is composed of an outside waiting area like the porch,
marquee or lanai and an inside waiting area like foyer or entrance
hall. It provides for and controls the flow of traffic into and out of a
building.
The main entrance provides access to the house. It is the one through which
guests are welcomed and from which all major traffic patterns radiate. The
main entrance should be readily identifiable. It should provide shelter to
anyone awaiting entrance.
The service entrance provides access to the house through which supplies
can be delivered to the service areas going through other parts of the house.
It should also provide access to parts of the service area like the garage,
laundry or workshop.
The special-purpose entrances and exits do not provide for outside traffic.
Instead they provide for movement from the inside living area of the house
to the outside living areas. A sliding door from the living area to the patio is
70
a special-purpose entrance. It is not an entrance through which street,
drive, or sidewalk traffic would have an access.
7. Garage and Carports.
A garage is an enclosed structure designed primarily to shelter an
automobile. It maybe used for many secondary purposes – as a
workshop, as a laundry, or for storage space. It is usually attached to
the house in some manner to provide a sheltered entry.
A carport is a garage with one or more of the exterior walls removed. It
may consist of a free-standing roof completely separate from the
house, or it may be built against the existing walls of the house.

LO4. Use of appropriate scale in drawing a Floor Plan
Scales
The architectural draftsman normally uses an architect’s scale for reducing
and enlarging the scale size measurement.
There are two system of
measurement, Metric system and English system.
Metric System
73
Always remember that the smallest the number used in metric scale,
the bigger the size in the triangular scale whereas, the largest the number
used the smallest size of actual measurement.
1:05 m.
1: 100 m.
1:10 m.

1: 50 m.
1: 600 m.
1:75 m.
1:1000m.
Note: The scale of 1:1000 m. or more is being used in Lot Plan and other
topographical drawings.
Full size scale
The 1:1 is a full size scale and each division measures 1 mm. in width
with the numbering of the calibrations at 10mm intervals. This same scale
is convenient for ratios of 1:10, 1:100, and 1:1000
Half size Scale
The 1:2 is one-half size scale and each division is equals to 2 mm.
with the calibration numbering at 20-unit intervals. In addition, this scale is
convenient for ratios of 1:20, 1:200, and 1:2000.

Legal Provisions:

Section 806 of the National Building Code (NBC). Size and
Dimension of Rooms:
a. Room for human habitations should be 6.00 square meters with at
least a dimension of 2.00 meters.
b. Kitchens should be 3.00 square meters with at least a dimension of
1.50 meters.
c. Bath & Toilet – 1.20 square meters with at least dimension of 0.90
meters.

Section 1207. Stairs, Exit, and Occupant Loads.
Width and Height. Every required exit doorway shall have a size to
permit the installation of a door not less than 900 millimeters in width
and not less than 2.00 meters in height.
Stairways width. Stairway serving an occupant load of more than 50
shall not be less than 1.10 meters. While stairway serving an
occupant load of 50 or less shall be 900 millimeters wide.
Rise and run. The rise of every step in a stairway shall not exceed 200
millimeters and the run shall not be less than 250 millimeters.
Other guidelines must be observed in the arrangement of rooms
in drawing floor plan:
1. Built-in cabinets or closets are usually found in the bedrooms,
kitchen, and dining room. Open shelves may be constructed in the
kitchen and dining room.
2. In some one-storey houses, the bedrooms toilet, and bath are
elevated from the other rooms. In this case, the stairs leading to
these rooms must be indicated on the floor plan. Two or three
steps, each has 18 or 19 cm high from each other and 25 cm wide,
may be shown in the plan. All these measurements must be drawn
to scale.
77
3. Since most of the time is spent by the members of a family in the
bedrooms at home, these rooms must be located far from noise,
dust, and polluted air coming from garbage pits or from the
kitchens and toilets of the neighboring houses.
4. If furnitures and house appliances are to be shown in each room,
these furnishings should be drawn on the same scale in the floor
plan.
5. If the floor plan will be traced on tracing paper in order to indicate
the electrical or water connections, these furnishings should not be
shown on the tracing.
6. In presentation drawings, the landscaping around the floor plan
may be added.
7. It is on the floor plan where the cutting plane lines for at least two
full-sectional elevations (cross and longitudinal) are indicated.
These sectional elevations are usually labeled as Section A-A and
Section B-B, depending on the capital letter used at the extremities
of the cutting plane lines. These cutting plane lines need not be
continuous or straight. They are often drawn in colored ink. ( see
illustration)
8. Windows and Doors symbols should be indicated in the outer walls
of the floor plan opposite to door and windows openings to
determine the total number and specification.
Entrance and Exit. There shall be at least one entrance and another
one for exit. Windows opening should be 10% of the total floor
square area according to the National Building Code.
Example:
Bedroom size of 3.00m x 40.00 = 12 square meters x 10% = 1.20m
window width opening.
Concrete Hollow Blocks (CHB) for walling and partitions
Sizes:
78

CHB - 0.10 T x 0.40 W. x 0.20 H. (4” T x 16”W x 8”H) is used for
interior walls or sometimes exterior wall with no heavy loads.

CHB - 0.15 x 0.20 x 0.40 (6” x 8” x 16”) is used for exterior wall
sometimes for interior wall.

Plastering of CHB wall should not be less than 0.015 mm. or not more
than to 0.05 cm in thickness.
Note:
In lay outing floor plan walls, it should be scaled with same sizes of all
actual materials to be used. If the occupancy wants to use 0.10 x 0.20 x
0.40 CHB plus plastering of 0.015 mm thickness on both side walls, the
total thickness of the wall is 0.13 cm. On the other hand, likes to use 0.15 x
0.20 x 0.40 CHB plus plastering of 0.015 mm thickness on both sides a
total average is 0.018 cm. since it is very hard to layout the accurate scale of
0.18 wall thickness, so most draftsman prefer to use 0.20 cm. wall in lay
outing floor plan.
Wall Openings
Entrance door is preferably with 0.90 cm. to 1.00 m. width.
Bedroom door has a minimum width of 0.80 cm.
Toilet and Bath door have a minimum width of 0.70 cm. to 0.80 cm.
Minimal width of windows is preferably 0.60 cm.
Other appliances and fixtures are required to be drawn in the floor plan
for space requirements
Eave lines are hidden roof lines which also indicated in the floor plan.
Trees, Plants symbols are required to be drawn in the development of site
plan if needed.

system.
Types of Roofs
There are different types of roofing system that are commonly used in
the building construction. The following are:
1. Gable Roof has a pitch on two sides but no pitch on the gable ends. This
type of roof is used extensively on Philippines bahay kubo and raw
houses in subdivision. The pitch or angle of a gable roof varies from the
high pitch roofs found on chalet A-frame style buildings to the low pitch
roofs found on most ranch homes.
95
GABLE ROOF
2. Hip roofs are used when eave-line protection is desired around the entire
perimeter of the building. Hip roofs are very popular in warm climates.
they are commonly used on Regency and French Provincial homes.

Roof Plan
A roof plan is one showing the outline of the roof and the major object
lines indicating ridges, valleys, hips and openings. The roof plan is not a
framing plan, but a plan view of the roof. To develop a roof framing plan, a
roof must be stripped of its covering to expose the position of each
structural member and each header. The roof plan can be used as the basic
outline for the roof framing plan. Below are samples of blueprint drawings
of roof plans, roof framing plan and other informative drawings.

The Importance and Purpose of Ceiling in the
building
116
Ceiling plan is an outline of the ceiling that shows the overhead
interior surface of a room.
Ceiling is designed with the following purpose:
i.
It prevents the penetration of the heat of the sun inside
the building.
ii.
It adds beauty inside the building especially when it is
well-designed.
iii.
It serves as thermal insulator that adds to the aesthetic
beauty of a house.
iv.
Various lighting fixtures can be hanged or placed to
highlight the interior design of the structure.
Important features that are shown in the ceiling plan
Ceiling plan can be shown into two presentations:
a. Ordinary presentation of ceiling plan. This shows the following:
1. Ceiling board
2. Partitions
3. Ventilation
4. Label which indicates the type of ceiling materials
5. Dimensions
b. Reflected ceiling plan. It is a drawing, which shows the items that
are located on the ceiling of a room or space. It is referred to as a
reflected ceiling plan since it is drawn to display a view of the
ceiling as if it was reflected onto a mirror on the floor. This way the
reflected ceiling plan has the same orientation as the floor plan
associated with it. It is as if the ceiling was see-through and you
could see right through it from the floor below. Interior designers
draw reflected ceiling plans when designing spaces.
The following features that are shown in the reflected ceiling plan:
1. Lighting fixtures
2. Ventilation
117
3. Smoke detector
4. Wood moulding
5. Ceiling board
Important considerations in ceiling plan
There are many design elements to consider in designing the
ceiling plan
1. Consider the distance from floor line to ceiling line
level.
2.
Study the 3-D aspects of volumes and space.
3. Consider using unexpected materials or finishes.
4. Consider the light reflection and sound absorption.
In accordance with the National Building Code of the
Philippines (PD 1096) Section 805: Ceiling Heights
v.
Habitable rooms provided with artificial ventilation have ceiling
heights not less than 2.40meters. which is measured from the floor
to the ceiling; provided that for buildings of more than one-storey,
the minimum ceiling height of the first storey shall be 2.70meters.

LO7. Draft Elevation and Section
126
An architectural elevation is a view of a building showing its height
dimension. When elevations show the exterior of a residential unit, they are
simply called elevations. Interior elevations show the inside of a building.
Elevations are the exterior views of a building. They are necessary in as
much as they show the height of the building and its appearance on each
side. Normally, the four elevations are sufficient to describe the appearance
of the residential building.
Elevation drawings are orthographic drawings. They show the exterior
of a building. The elevation s that part of the building that people see and
observe, hence, it is the part they use to judge the structure.
Normally, the design of the floor plan precedes the designs of the
elevation, because both have a continual relationship in the entire design
process. Flexibility is possible in the design of elevations, even those
designed from the same floor plan.
The designer should keep in mind that only horizontal distances can
be established on the floor plan, while that of the vertical distances such as
height of doors, windows and roofs must be shown on the elevation.
As these heights are established, the appearance of the outside and
functioning of heights as well as the internal functioning of the building
must be considered.
Preliminary Sketches
The location and proportion of features are very important in the
drawing of elevation. Main attention is given to the proportion of walls and
openings. Some of the things to consider in the drawing of elevations are;
1. Proportion – which deals with the size and shape of areas and their
relation to one another.
2. Fenestration – deals with the arrangements of windows and doors in a
wall.
3. Harmony refers to all features that should harmonize to present a
uniform elevation.
4. Shadows refer to a simple elevation, which can become interesting
when designed to take advantage of shadows.
Finished Sketches
127
The finished sketch may be carefully drawn with the use of drawing
instruments. Since these are fairly large scale drawings the exact size of all
features together with their correct representation must be considered.
In the drafting of elevations, these are some of the things to consider:
1. Window and Door Size – must be chosen from a manufactures catalog
which offers great variety of sizes. The sizes must be standard that it
conforms to the provisions of the building code.
2. Window and Door Representation –in elevation may be drawn simply.
3. Material Representation – may be shown by drawing only a few lines,
like bricks.
4. Footings and Walls are hidden lines used to indicate location of
footings.
5. Labeling views can be done in two methods by labeling it with views
as in front, rear, left and right side elevations, or by using compass
orientation as in north, south, east, and west directions.
6. Dimensioning on elevations are limited to vertical dimensions are
shown on the plan.
7. Changes are additions necessary after all the other drawings have
been completed.
Elevations are the exterior views of the building. The front view of the
building is always referred to as the front. The other elevations are named
according to their position in relation to the front, i.e. right elevation, rear or
back elevation, left elevation.
128
Eave is the lower portion of a roof which extends beyond the wall.
Pitch is the term applied to the amount of roof slope, It is found by
dividing the heights of the span
Elevation Projection
Elevation drawings are projected from the floor plan of an
architectural drawing just as the views are projected the front view of an
orthographic drawing. All six views are rarely used to depict architectural
structures, instead only four are used. These four elevations are normally
projected on the floor plan.

Elevation Dimensioning
Dimensions on elevation show the vertical distance from a datum line,
which is a reference line that remains constant. Dimensions on elevation
show the height above the datum or the ground line. Dimensioning
132
elevations must comform with basic standards to ensure consistency of
interpretation.
Here are some of the rules in dimensioning:
1. Vertical elevation dimensions should be read from the right of the
drawing.
2. Levels to be dimensioned should labeled with a note, term or
abbreviation.
3. Room heights are shown by dimensioning from the floor line to the
ceiling line.
4. The depth of footings (“footer”) is dimensioned from the ground line.
5. Heights of windows and doors are dimensioned from the floor plan to
the top of windows or doors.
6. Elevation dimensions show only vertical distances (height). Horizontal
distances (length and width) are shown on the floor plan.
7. Windows and doors may be indexed to a door or window schedule, or
the style of the windows and doors may be shown on the elevation
drawing.
8. The roof pitch is shown by indicating the rise over the run.
9. Dimensions for small, complex or obscure areas should be indexed to
a separate detail.
10.
Ground-line elevations are expressed as heights above a datum
point.
11.
Heights of chimneys above the ridge line are dimensioned.
12.
Floor and ceiling lines are shown with hidden lines.
13.
Heights of planters and walls are dimensioned from the ground
line.
14.
Thickness of slabs are dimensioned.
15.
Overall height dimensions are placed on the outside of

Draft Elevations and Section
Procedure in drafting elevations:
1. Lay-out the elevation very lightly using a sharp, hard pencil.
Using a divider or a scale, transfer horizontal dimensions from
the floor plan. A scale of 1: 100 or 1:50 meter is used and
indicated in the title block or near the drawing. If the plan and
section are drawn to the same scale as the required elevation,
the floor plan may be taped in position and dimension projected
directly using triangle and T-square.
Windows and door are located horizontally by projecting
from the plan, They are located vertically by projecting from the
window and door details or simply by aligning the top of the
window with the top of the door.
2. Locate the vertical distance of ceiling from floor line, ridge to
ceiling line and natural ground to finished ground line. indicate
also the height of doors and windows.
3. Indicate the thickness of walls, fascia board and other materials
seen on elevation and darken the lines to highlight them.
136
4. Draw the elevation details and other architectural materials.
The elevation details to be included will vary depending
upon the style of the house, in the case of a residence, the
following details are added:
1. roof fascia
2. roof beams
3. window representation
4. gradelines
5. material representation
6. darkened building outline
5. Indicate the dimension of the vertical distance from
the natural ground line to the floor line and the floor line
ceiling, and ceiling line to ridge line.
137
Added elevation dimensions and notes are.
1. height of roof
2. height of other features such as masonry wall
3. heights of wall
4. roof slope indication
5. window schedule
6. title and notes indicating materials
INFORMATION SHEET # 1.2
LO7. Draft Elevations and Sections
138
Sections
The designer shows the internal construction of a building by means
of a section.
Section drawings are prepared for interior details needed to guide
construction. Interior elevation drawing shows builders how to construct
and install special features of a home. These features include closets,
cabinets, bathtubs and other special details.
Techniques for preparing interior elevation drawings are the same as
for exterior elevations. Use a floor plan to locate key vertical lines after
horizontal dimensions have been indicated.
Section is a type of drawing which shows the interior or inside of a
building or structure.
Cross section is a type of section where the cutting-plane line is drawn
horizontally.
Longitudinal section is a type of section where the cutting-plane is
drawn vertically.
Cutting plane line a heavy line which shows the exact location where
the plan is cut.
The following are the types of sections used in architectural drafting.
1. Structural section shows the entire building construction. This is
useful in planning for structural strength and rigidity, determining the
length of members and specifying sizes.
2. Wall section shows the construction of a typical wall. This section is
useful in determining sizes and material specification for all rough
members.
3. Detail section shows any deviation from a typical section. It is drawn
to a larger scale.

Full Sections
142
Architects prepare drawings that show the building cut in to half to
show the internal structure. This is known as longitudinal section, meaning
lengthwise. When it is cut across, it is called transverse section. It is
imagined that a plane is passed through the building cutting it in half by a
cutting plane line.
There are different ways of drawing the cutting plane line, most
especially if it interferes with dimensions as shown in these figures.

Presentation drawings
The purpose of the presentation drawings is to show the proposed
building in an attractive setting surrounding at the proposed site. It must be
shown in an attractive presentation to easily arouse the client’s interest.
Presentation drawings consist of the preliminary designs:
1. Floor plan
2. Elevations plan
3. Perspective
4. Sections
5. Sample details
The floor plan must be presented to the client to give him a clear
picture of interior portion of the proposed building particularly the location
of bedrooms, living room, dining, kitchen, comfort rooms and other elements
inside the building.
153
The elevation plan is purposely to show the height of the building
particularly the distance from floor line to ceiling line and the distance from
bottom line and top of a ridge.

Commonly, presentation drawings are usually presented in the form of
perspective views with colors and shading and floor plan. This is purposely done
because presentation drawings are actually used to sell an idea or concept. The
elevation plan, section and sample details are only used for further communication
between the clients and the architect or draftsman to arrive at a final plan or
design of the house. These are usually shown in the form of illustration.
PERSPECTIVE DRAWING
155
Perspective Drawing
The following are important principles to be considered in the
preparation of presentation drawings particularly perspective views, the
following are:
1. Selection of appropriate view of the proposed building
In the presentation, the frontal portion must be given more
emphasis by the designer because this is the very part of the building
that is always exposed to the viewers’ eyes.
2. Proportion of the perspective view
This means that proper location of the vanishing point must be
considered in making the perspective view.
3. Inclusion of landscaping
Landscaping must be included in the preparation of perspective
view because it adds attraction to the viewer.
4. Other elements like car, human figure and etc. must also be included
in the presentation of perspective view because these would serve as
additional attraction of the drawing.
156
OPERATION SHEET # 8.1
LO8. Perform Presentation Drawings
Presentation drawing is commonly accomplished in the form of
perspective view especially when the draftsman or architect is negotiating a
drafting service to a certain client. However, floor plan, elevations plan and
section drawings are also prepared to be shown to the client.
The following are the procedures in the preparation of presentation
drawing:
1. Draft the floor plan according to the desired size and shape.
2. Draft the elevation plan based on the floor plan.
3. Draft section drawing based on the elevations and floor plan.
4. Draft the perspective view.
