Unit 5 Fundamental Drawing Practices Flashcards
detail
A type of drawing showing a specific detail of the construction. Details are normally drawn at a larger scale than other drawings.
electrical plan
A plan view drawing showing the layout of the electrical wiring and fixtures. Also called electrical drawing.
elevation
In surveying, the height of a survey marker above sea level; a measurement on a plot or foundation referenced to a known point. In architectural drafting, a drawing showing the front view, rear view, or one of the side views of a structure.
floor plan
A plan view showing room sizes and locations and many construction details. For simple construction, the floor plan may contain all of the needed information.
foundation plan
A plan view showing the dimensions and details of a building’s foundation system, including footings, walls, and piers.
framing plan
A plan view showing the layout of the structural members supporting a floor or roof.
graph paper
Paper displaying a grid of light lines, used to help keep lines straight and make proportioning easier.
inclined lines
Straight lines that are neither horizontal nor vertical.
mechanical plan
A plan view drawing showing the location of mechanical equipment in a building, such as the HVAC system and plumbing system. Also called mechanical drawing.
orthographic projection
orthographic projection: The projection of an object as viewed from six different perpendicular directions. The basis of architectural plan and elevation drawings. Also called orthographic drawing.
perpendicular projectors
In orthographic projection, lines between views that connect common points.
plan view
A drawing that shows one floor of a building from directly above. Also called plan drawing.
plumbing plan
A plan drawing showing the layout of the water distribution and drainage systems.
proportion
The size of a portion of an object relative to the entire object or another portion.
rise
In roof construction, the vertical distance from the top plate to the ridge of a roof. In stair construction, the vertical distance between floors.
run
In roof construction, the horizontal distance from the wall supporting the bottom of the rafter to the ridge board. In stair construction, the total horizontal length of the stairway.
section
View showing the building as if it were cut apart. Sections show walls, stairs, and other details not clearly shown in other drawings. Sections are usually drawn in larger scale than the elevations and plan drawings
sheathing
The boards or panels that cover the studs and rafters of a building to which finishing materials are applied.
triangle-square method
A commonly used method of sketching arcs and circles.
unit method
A technique useful in estimating proportions. It involves identifying a unit that is common to both the width and height of the object.
