1
Architecture scale
extended scale = 1', so if there are 12 tics each tic is 1 inch, etc.
2
Tape Measurer
Use a 1/4" = 1' scale
3
Construction Drawing pyramid
construction drawings
Othrographic||||||||||||||&|||||||||||| Pictorial
4
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
5
Top view
plan view - foundation plan, floor plan (recommend starting here) ceiling plan, plumbing plan, electrical plan.
6
Front view
Main elevation, Section
7
Right view
Elevation, Section
8
Floor Plan
4' cut line about the floor. shows lay out of the building, rooms, birds eye view without roof above
9
Vertical Cut lines
show heights and vertical relationships within a building
10
Pictorial Construction Drawings
-Isometric
-Oblique
-Perspective
11
Isometric Drawing
-Most common technical drawing
-Obj is drawn w/ 30/60 degree angles
-Dimensionally accurate along angles
-to scale
-not perspective
12
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
13
Perspective
-Horizon line, 2 vanishing points
-EXACTLY AS YOU SEE IT FROM A GIVEN POSITION
14
Special Views
Large scale drawings which show features that do not appear on the plans and elevations
Types:
-Section
-Detail
-Exploded View
15
Section drawing
-most common
-gives clear picture of the inside or hidden features of an object
-depicts and instructs the most
16
Detail drawing
Do not have cutting plane indication but are noted with a code
17
Exploded view
used to show the assembly or disassembly of the obj that has several removable parts, layered effect
18
Visible Line
-Used for walls, doors, windows, etc
-Heavy unbroken lines used to indicate visible edges of an obj
19
Hidden Line
-Medium lines w/ short evenly spaced dashes.
-used to indicated concealed edges.
20
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.
21
Dimension line
-Thin lines terminated w/ arrowheads at each end used to indicate distance measured
-will reach from 1 extension line to another
22
Extension line
Thin unbroken line used to indicate extent of dimension
23
Leader line
-Thin terminated w/ arrowhead or dot at one end
-Used to indicate a part, dimension, or other reference.
24
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.
25
Break (Long)
-Thin solid ruled line w/ free hand zig zags
-used to reduce the size of the drawing requirement to delineate obj and reduce detail
26
Break (Short)
-Thick solid free hand zig zag lines used to indicate a short break
27
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
28
Cutting plane for complex or offset views
-Thick short dashes
-used to show offset w/ arrowhead pointing in direction viewed
29
what are the 2 types of symbols
architectural and material
