Blueprints Flashcards
Architecture scale
extended scale = 1’, so if there are 12 tics each tic is 1 inch, etc.
Tape Measurer
Use a 1/4” = 1’ scale

Othrographic Drawings
- 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
Top view
plan view - foundation plan, floor plan (recommend starting here) ceiling plan, plumbing plan, electrical plan.
Front view
Main elevation, Section
Right view
Elevation, Section
Floor Plan
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
- Isometric
- Oblique
- Perspective
Isometric Drawing
- Most common technical drawing
- Obj is drawn w/ 30/60 degree angles
- Dimensionally accurate along angles
- to scale
- not perspective
Oblique Drawing
- 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
Perspective
- Horizon line, 2 vanishing points
- EXACTLY AS YOU SEE IT FROM A GIVEN POSITION
Special Views
Large scale drawings which show features that do not appear on the plans and elevations Types: -Section -Detail -Exploded View
Section drawing
- most common
- gives clear picture of the inside or hidden features of an object
- depicts and instructs the most
Detail drawing
Do not have cutting plane indication but are noted with a code
Exploded view
used to show the assembly or disassembly of the obj that has several removable parts, layered effect
Visible Line
- Used for walls, doors, windows, etc
- Heavy unbroken lines used to indicate visible edges of an obj
Hidden Line
- Medium lines w/ short evenly spaced dashes.
- used to indicated concealed edges.
Center Line
- 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.
Dimension line
- Thin lines terminated w/ arrowheads at each end used to indicate distance measured
- will reach from 1 extension line to another
Extension line
Thin unbroken line used to indicate extent of dimension
Leader line
- 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.
