Course Syllabus
Syllabus--A summary outline
of a concurrent enrollment
course for
Weber State
University
“It is the peculiarity of
knowledge that those who
really thirst for it always get
it.”
“If you don’t have time to do it
right at first, when will you
have time to do it over?”
“It’s a cinch by the inch, but
hard by the yard!”
“We learn wisdom from failure
much more often than from
success. We often discover
what will do, by finding out
what will not do.”
Course Catalog Description
A course for Drafting Technology students
who wish to broaden his or her basic
drafting skills in the field of residential
architectural drafting. This course covers
procedures used in developing a complete
set of residential plans. Includes
architectural drafting standards, handlettering procedures, and code requirements.
• The term Details covers the broad category of
isolated and enlarged drawings
• Details along with the plans, elevations, etc., and
specifications form the complete set of construction
documents.
• Knowledge of construction details should give a
clear assembly of parts that form a portion of the
total package of construction.
• Knowing the particulars of materials that make-up a
detail allows the drafter, designer, or architect to
conceptualize faster and get the work completed.
Course Disclaimer
The instructor reserves the right to make
changes, deletions, corrections, or additions
during the course. These changes will be
announced in class. Anyone with special needs
or learning disabilities needs to bring that to my
attention.

• 1--No lines are on your drawing vellum to start with,
therefore needed to give size of lettering.
• 2--Architectural drawing is a form of technical
drawing, tools and instruments are used to create
straight line and legible work.
• 3--All lettering is done using guidelines.
• 4--General rule for guide lines for lettering height:
– 1/8” for notes and dimensions
– 3/16” for room titles
– 1/4” for drawing titles
Architectural Lettering Styles
• Handout Information:
– Proficiency in lettering is valuable and important
– Make lettering consistent, readable, legible, and fast
is the ultimate
– Architectural lettering generally has evolved from
many influences
– Usually architectural offices have a uniform style of
lettering
– Practice, be persistent, and make the effort to do
“Triangle or Straight Edge Vertical Stroke” lettering
it will be worth it
– A requirement of the course

coordinator of many drafters
- May design residential size building and dwellings
• Architect - Must be licensed to practice
– Designs residential and commercial buildings
– Additional schooling beyond high school required
– A variety of architectural careers available
Architectural Careers
• Engineer - Work is more technical and
requires high level of math and science
– Education beyond high school required
– A variety of engineering fields available

certification
Architectural Careers
• Illustrator - Combines artistic and
architectural skills to produce drawings
• Model Maker - Follows plans to build scale
models
Architectural Careers
• Specification Writer - Understands the
construction process to write necessary
details of the plans
• Inspector - Checks plans to ensure codes
and laws have been followed
Design Basics
• Financial Considerations - Estimates for
labor and material costs are calculated
• The Client - Important to ensure that their
desires in the project are being met
accordingly
The Design Process
• Initial Contact - The designers and
client meet to discuss design ideas, fees,
schedules, and ensure personalities are
compatible
The Design Process
• Preliminary Design Studies - Following the
research, bubble drawings and scaled
sketches are created
– Rooms must be considered throughout this
stage and may include room usage, furniture
layout, and size requirements
The Design Process
• Initial Working Drawings - A drafter begins
to make working drawings that include the
foundation, plot, roof, electrical, cabinet,
and framing plans
• Final Design Considerations - A conference
with the client is needed to discuss the
initial working drawings
The Design Process
• Completion of Working Drawings - Drawings
include at least:
–
–
–
–
–
(A) Architectural
(S) Structural
(M) Mechanical
(E) Electrical
(P) Plumbing
The Design Process
• Permit Procedures - Once all plans are
complete appropriate permits must be
secured before construction begins
• Job Supervision - Although not usually
done by the designer, sometimes he/she is
required to go to the site and solve
problems.

Drafting Supplies
Drafting Instruments
Drafting Machines
Scales
Drafting Supplies
• Mechanical Pencils - The lead is manually
inserted and sharpened as needed
• Automatic Pencils - The lead advances as
button or tip is pushed
• Lead Grades - Depends on the type of line
– Thick Lines - 2H to F
– Thin Lines - 4H to H
Drafting Supplies
• Pencil Motion - Keep pencil tilted at 45º
with the direction of travel
– Provide even pressure to create sharp crisp lines
– Slowly Rotate the mechanical pencil as the line
is drawn
– Practice this technique as often as possible
Drafting Supplies
• Technical Pens - Used to create inked lines
• Erasers - Use the correct eraser for the job
– Do not press too hard to rip the material
– Erasing shields protect good lines
– Use a dust brush to remove the eraser particles
Drafting Instruments
• Compasses - Used to draw circles and arcs
– Drop-bow is used for small circles
– Center-wheel is used by professional drafters
– Beam is used for large arcs or circles
• Keep the compass needle sharp and the lead
point sharpened like a chisel point
Drafting Instruments
• Dividers - Used to transfer dimensions or
divide distances
• Parallel Bar - Slides up and down the
drafting board by cables mounted on
pulleys
• Triangles - Two standard types
– 30º-60º-90º is known as 30º-60º triangle
– 45º-45º-90º is known as 45º triangle
Drafting Instruments
• Templates - A plastic sheet that contains
standard symbols used for tracing
– Be sure the scale matches your drawing
– Keep both sides clean
• Irregular Curves - There is no constant radii
and is commonly called a French curve
Drafting Machines
• Arm Drafting Machine - The arm clamps to
the table and the head can rotate to a variety
of angles with different scales attached to it
• Track Drafting Machine - The traversing
arm moves left and right across the table
and the head can also lock and pivot
Scales
• Notation - Scale of the drawing is noted in
each title block
– Architecture - 1/4”=1’-0” or 1”=1’-0”
– Civil - 1”=50’ or 1”=500’
• Metric - Scale is based on the meter (m)
unit
– Millimeter (mm) is most commonly used on
drawings
Scales
• Architect’s Scale - Contain 11 different
scales
–
–
–
–
–
Locate the correct scale before beginning
Ten of the scales are based on the inch unit
Other scale is divided into 1/16th of an inch
Be careful when reading from left to right
The 1/4”=1’-0” is the most common scale
Scales
• Civil Engineer’s Scale - Contain 11
different scales
– Locate the correct scale before beginning
– The scales are based on the inch unit in
multiples of 10
– Be careful when reading from left to right
– The 50 scale is most popular

Papers and Films
Sheet Sizes & Layout
Diazo Reproduction
Selecting Papers and Films
• Durability - Ability to last with wear and
tear
• Smoothness - Ability to accept line
work and lettering
• Erasability - Lines are removed without
ghosting (residue left after erasing)
Selecting Papers and Films
• Dimensional Stability - Maintaining size
in different atmospheric conditions
• Transparency - Ability for light to pass
through easily
• Cost - Determined by the intended use
of the drawings
Types of Papers and Films
• Vellum
– Designed to accept pencil or ink
– Least expensive
– Good smoothness and transparency
• Polyester Film (Mylar®)
– More expensive, but dimensionally stable
– Good durability, erasability, and transparency

• Usually preprinted on drawing paper
• Borders are thick lines that surround the entire
drawing
• Leave room on the left side for binding

Diazo Reproduction
• Commonly known as “blue-prints”
• Ultraviolet light passes through a translucent
drawing to expose chemically coated paper
• Machine speed is determined by the diazo
material and the transparency of the original
• Be sure to run a test paper to make sure the
settings are correct
Diazo Reproduction Steps
1. Place the diazo material on the feedboard with
the yellow side up
2. Place original drawing on the diazo material with
the image side up and align edges
3. Push material into the diazo together
4. Once exposed, separate paper and feed diazo into
the developer section
Diazo Reproduction Safety

Do not inhale ammonia fumes
Wash skin immediately if ammonia is spilled on
it
• Do not look directly at ultraviolet light
