An Introduction to the Course ARCHITECTURAL (RESIDENTIAL) DRAFTING Department Mission Statement The mission of the Drafting Technology Department coincides with the institutional mission: to provide quality vocational and technical training to students for employment, to assist students to attain educational and personal goals, and to provide occupational training and vocational/technical information for the community. Class Standards • Dress standards – good taste, common sense, high moral standards are the watchwords for dress and grooming – no hats in classroom 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.

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 Chapter 3 Drafting Media and Reproduction Methods Links for Chapter 3 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 Sheet Sizes and Layout • Sheet sizes recommended by ANSI A 8 1/2 X 11 or 11 X 8 1/2 B 17 X 11 C 22 X 17 D 34 X 22 E 44 X 34 F 40 X 28 Sheet Sizes and Layout • Sheet sizes used by Architects A 9 X 12 B 12 X 18 C 18 X 24 D 24 X 36 E 36 X 48 F 48 X 72 Title Blocks and Borders • Identifies the company that has made the drawings • Placed along the right side of the sheet • Usually preprinted on drawing paper • Borders are thick lines that surround the entire drawing • Leave room on the left side for binding Title Block Information • Title blocks contain the following information – – – – – – Drawing Number Company Information Project or Client Drawing Name Scale Drawing – – – – – Date Drawn by Checked by Architect or Designer Revisions 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 • • • • Wear eye protection when changing ammonia Avoid skin contact with ammonia Do not inhale ammonia fumes Wash skin immediately if ammonia is spilled on it • Do not look directly at ultraviolet light
