Flashcards in Blueprints Deck (35)
extended scale = 1', so if there are 12 tics each tic is 1 inch, etc.
Use a 1/4" = 1' scale
Construction Drawing pyramid
-show every part of the parallel drawing plane true relative size and position
-6 views - top, bottom, front, back, left, right
-3 main views - top, front, right
-objects presented as if they were viewed through a transparent drawing plane
-show elevation if they know where building is going
plan view - foundation plan, floor plan (recommend starting here) ceiling plan, plumbing plan, electrical plan.
Main elevation, Section
4' cut line about the floor. shows lay out of the building, rooms, birds eye view without roof above
Vertical Cut lines
show heights and vertical relationships within a building
Pictorial Construction Drawings
-Most common technical drawing
-Obj is drawn w/ 30/60 degree angles
-Dimensionally accurate along angles
-Flat front view with any angle (typically 45 degrees) coming off to indicate depth
-elevation is drawn looking straight at the obj
-allows for more detail on one elevation
-all lines are dimensional
-Horizon line, 2 vanishing points
-EXACTLY AS YOU SEE IT FROM A GIVEN POSITION
Large scale drawings which show features that do not appear on the plans and elevations
-gives clear picture of the inside or hidden features of an object
-depicts and instructs the most
Do not have cutting plane indication but are noted with a code
used to show the assembly or disassembly of the obj that has several removable parts, layered effect
-Used for walls, doors, windows, etc
-Heavy unbroken lines used to indicate visible edges of an obj
-Medium lines w/ short evenly spaced dashes.
-used to indicated concealed edges.
-Thin lines made up of long and short dashes. alt. spaces and consistent in length.
-used to indicate symmetry about an axis and location of centers.
-Thin lines terminated w/ arrowheads at each end used to indicate distance measured
-will reach from 1 extension line to another
Thin unbroken line used to indicate extent of dimension
-Thin terminated w/ arrowhead or dot at one end
-Used to indicate a part, dimension, or other reference.
Phantom or Datum line
-Medium series of one long dash and two short dashes evenly spaced ending w/ long dash.
-used to indicate alternate position of parts, repeated detail or a datum plane, i.e. door swings or movable walls.
-Thin solid ruled line w/ free hand zig zags
-used to reduce the size of the drawing requirement to delineate obj and reduce detail
-Thick solid free hand zig zag lines used to indicate a short break
Cutting or viewing plane
-Thick short dashes
-used to show offset w/ arrowheads to show direction in which section or plane is viewed or taken
Cutting plane for complex or offset views
-Thick short dashes
-used to show offset w/ arrowhead pointing in direction viewed
what are the 2 types of symbols
architectural and material
