Drafting Paper • Is paper which has been specifically prepared for use in technical drawings • Comes in a range of sizes and styles to meet specific needs • Is smooth, erasable and made from different materials including vellum and film 60

Drafting Tape • Is a specially-prepared tape used to adhere drawing paper to a working surface • Is easily removed and does not leave a sticky residue when removed 61

A Drafting Machine • Is mounted to the drawing board • Has rulers whose angles can be adjusted with a controlling mechanism • Allows for easy drawing of parallel lines 62

A Scale • Is a tool which enable engineers, architects and contractors to obtain measurements of buildings and structures from scaled drawings and maps • Has multiple units of length which are in proportional increments • Is three-sided or beveled • Includes architectural and engineering 63

A Compass • Is used to draw circles and arcs • May also be used to measure distances between points 64

A Drafting Triangle • Is a tool used for drawing lines at specific angles • May be used to draw vertical or sloping lines • Can be used as a straight edge to connect points • May also be known as a square set 65

A T-square • • Is used for horizontal lines and parallel lines May align other drawing instruments May be used as a straight edge Uses the edge of the drawing board for support • Is commonly used for drawing or measuring right angles 66

A French Curve • Is a template for drawing smooth curved lines • Is used for drawing curves which cannot be drawn with a compass 67

A Template • Contains pre-dimensioned holes in the correct scale to accurately draw a symbol or a sign • May be used when standard symbols are to be drawn repeatedly • Uses standard symbols, such as: – circles – triangles – squares 68

A Lettering Guide • Is a type of template placed against a straight edge and used to draw horizontal guidelines for letter height 69

Computer Aided Drafting (CAD) • Refers to software programs offering a wide variety of applications which make the design and drafting process efficient – include customized screen menus to fit specific problems or needs • processes and capabilities vary based on software type Fun Fact: For example, one of the top CAD programs is Turbo. CAD, which has numerous custom tool palettes, giving lots of design space. 73

Computer Aided Drafting (CAD) • Includes the following customization and feature options: – customizing and creating personal palettes – adding more objects to palettes – renaming images – adding free-floating tabs to allow quick access to common symbols, commands and other tools while drafting 74

Computer Aided Drafting (CAD) • Include applications to do the following: – work more efficiently with precision – complete plans, section and elevations – create 2 -D or 3 -D images – generate interior and exterior architectural and structural detail – easily modify drawings – create a database for manufacturing – construct photorealistic renderings for presentation and marketing 75

Project Planning, Design & Layout • Can begin once all site information and data has been collected analyzed – first step is creating a site plan, showing the layout of a project 77

The Design Process • Includes: – collecting information – schematic design – design development – construction documents – bidding – construction administration – construction 78

Collecting Information • Is when architects gather information to help understand the neighborhood, the site, the users of the building and any existing buildings • Includes taking photographs, sketching and interviewing the client 79

Collecting Information • May also include gathering data on the following: – path of sun around the site – direction of the wind – the climate – plant life around the site 80

Schematic Design • Focuses on creating the general framework to build the project on • Includes: – defining the general scope and conceptual design of the project • scale • relationships between building components – developing preliminary sketches • for client approval – gathering information on the construction site • site plan 81

Schematic Design • Considerations include: – zoning laws – distribution – circulation – lighting – ventilation – sizes, areas and shapes − − orientation height electrical layout location of doors and windows − line of sight 82

Zoning Laws • Refer to the physical development of land the types of uses of each property • Include: – regulations limiting the height, bulk and location of buildings – determining the area of yards or other open spaces – regulating the density of population in a given area 83

Distribution • Refers to the placement, location and arrangement of each room in relation to other rooms, such as: – the kitchen and dining room should be next to each other to facilitate easy food service 84

Circulation • Refers to the roads and highways around the structure • Also refers to the inside traffic which must be considered in planning – circulation and movement of occupants inside the structure should not be hampered by obstacles or be detoured as a result of poor planning – functional space is important 85

Lighting • Refers to the general illumination of any space • Should be one of the initial parts of any construction plan • Includes: – ceiling fixtures – wall sconces – skylights 86

Ventilation • Refers to the air flow through the building or structure • Removes heated air, smoke and gases from a structure with fresh air • Sites include: – roof – skylights – roof vents – ridge vents 87

Sizes, Areas & Shapes • Should be planned to scale to provide ample areas to accommodate the following: – furniture – appliances – pathways for movement inside the house – facilities 88

Orientation • Refers to the position and direction of sunrise and sunset – may be useful for energy consumption • Includes the wind direction in the area 89

Height • Limitations depend on: – type of building material used – dimensions of the stud – stud spacing – allowable deflection limit • Includes: – wall height – ceiling height Deflection – turning aside or deviating from a straight line 90

Electrical Layout • Should be planned based on codes and standards • Includes: – location of outlets – light switches – location of appliances 91

Location of Doors & Windows • Is an important aspect of improving ventilation, natural light and the architectural style • Considerations include: – rain – noise – outdoor temperature – orientation 92

Line of Sight • Refers to the openness of an area within the building or structure • May create a continuous flow of space from the open interior to the exterior • Considerations include locations of: – walls – wall openings – pony walls – windows and doors 93

Design Development • Occurs after schematic design • Includes: – refining drawings with the use of drafting tools or computer aided drafting – specifying requirements of a design – analyzing current design goals 94

Construction Documents • Are the actual presentation drawings • Include: – building plans or blueprints • include architectural drawings and elevations, as well as structural, mechanical and electrical drawings – specifications • covers materials and methods which should be used when constructing the project – supporting documents • used to add supplemental instructions and help resolve minor issues in the construction documents 95

Bidding • Is the process of submitting an offer to manage the responsibility of a construction project • Process starts with basic information taken from a blueprint – cost estimates – specifications – site information 96

Construction Administration • Must ensure the plans comply with all relevant building codes and regulations • Deals with clarifications and administers revisions if necessary • Protects the interests of the client and the integrity of the design 97

Construction • May include many changes to the blueprints • Is completed using the construction plans as a guide – once the project is completed, the designer uses the construction drawings to check that the building or structure matches the design exactly 98
