6.06Draw basic floor plans and elevations

GCFI• Ground Control Fault Circuit

Interrupter• This is a type of circuit (electrical

outlet) that helps prevent electrical shock

Architectural Drawings• Universal language• In proportion to actual size• ¼ inch = 1 foot, also called 1/48 or 1/4”=12”• CAD, CADD – computer aided drafting and

design• Now referred to as prints instead of

blueprints• Templates – plastic drafting tool for tracing

shapes onto a floor plan

Types of Drawings• Sectional-view taken from an imaginary cut

through of a building (7-6 p181 HD)• Exterior elevation-usually 4,one of each

side, drawing of outside of the house (7-5 HD p. 181)

• Interior elevation – shows a wall of a room, with furniture and architectural fixtures

Renderings – realistic drawing with colorExpensive done by handRequire expertiseDone by:

PencilInkWater colorColor pencilFelt tip

(continued)• Model – 3 D representation• Detail – up close and personal of a

small part of a floor plan or elevation• Specs = specifications=a book of

additional information that is not able to fit onto a floor plan

Assignment• Select a room from the house you

printed yesterday. Draw that room on graph paper. (floor plan)

• Create one wall interior and one wall exterior elevation of your house.

• Continue working on “Student Lounge” assignment

Alphabet of Lines• Vary in thickness and weight• Allow the drafter to communicate

ideas quickly and clearly

Alphabet• Phantom ____ _ _ ____ _ _ ____Show alternate positions, repeats, or

motion• Visible _____________ outline of

building or walls• Hidden ---------------- not visible in a

specific view

Alphabet (continued)• Center line ____ _ ____ _ ____ _ Shows center of an arc or circle• Dimension and extensionI-------- 4 ½” -------I size, distance• Break line (look in book) p. 178Show that the object continues on but

the entire view is not shown

Alphabet of lines• Section (crosshatch) //////////• Show that a feature has been sectioned

Assignment:• Use page 100 of the architectural drawing

to locate as many of the “alphabet of lines” Describe what they are showing
