SOC Blueprints Flashcards
- What are the types of construction drawings?
Orthographic
Pictorial
- How many view of an OBJ are there?
There are six.
Top, Front, Bottom, Right side, Left side, back
- What are the three main orthographic view?
Top (as seen from above) - Plan View: Foundation, Floor, ceiling, Plumbing, Electrical Plans Front - Main Elevation, Section Right Side - Elevation, Section
- What are the types of pictorial drawings?
Isometric (Most common type of pictorial drawing)
Oblique
Perspective
- What are the Isometric angles?
30 and 60 degree
- What is the oblique angle?
45 degree
- What is characteristic of Isometric?
It is dimensionally accurate along both angles and most common type of pictorial drawing
- What is characteristic of Oblique?
All lines are dimensionally correct. Elevation is drawn looking straight at the object.
- What is different about perspective?
Not dimensionally correct. Vanishing points
- What are the special views?
Section (most common)
- Gives a clear picture of the inside or hidden features of an object
Details
- Do not have cutting plane indication but are noted with a code
Exploded view
- Used to show the assembly or disassembly of an object that has several removable parts (Ex. Ikea furniture)
- What are the two common scale rulers?
Architect and Engineer
- What is purpose of architect ruler?
Architect ruler mainly used for building construction. It measures feet and inches.
- What is purpose of engineer ruler?
Normally used for site plans. It measures feet and tenths of a foot.
- What are the two North?
1) True North
Orients the drawing to actual North
2) Job North
Orients the person to the BLDG. based on site access.
- What is BOM stand for?
Bill of Materials
- What is CL stand for on a blueprints?
Center Line
- Which plan is the only plan to show true north?
Site plan
- What are construction drawings?
The written language of a building. Drawings detail the building components and materials of construction

- What are the two types of symbols?
Architectural and material
- What is the most common special view?
Section
- What is visible lines?
Heavy, unbroken lines. Used to indicate visible edge of an OBJ
- What is hidden lines?
Medium line with short, evenly spaced dashes. Used to indicate concealed edges.
- What is center lines?
Thin lines made up of long and short dashes alternately spaced and consistent in length.
- What is dimension lines?
Thin lines terminated with arrow at each end.
- What is extension lines?
Thin, unbroken line. Used to indicate extent of dimensions
- What is leader line?
Thin line terminate with arrowhead or dot at one end. Used to indicate a part, dimension, or other reference.
- What is phantom (Datum) line?
Medium series of one long dash and two short dashes evenly spaced ending with long dash. Used to indicate alternate position of parts.
- What is break (Long) lines?
Thin, solid ruled line with free-hand zigzags. Used to reduce size of drawing required to delineate OBJ and reduce detail.
- What is break (short) lines?
Thick, Solid free-hand lines, used to indicate a short break
- What is cutting or viewing plane lines?
Thick, short dashes. Used to show offset with arrowheads to show direction in with section or plane is viewed or taken
- What is purpose of architectural symbol?
It represents graphic symbols used in plans and drawings includes civil, plumbing and electrical.
- What is purpose of material symbol?
Used to graphically indicate the type of material being used in and around the structure (ie. Wood, steel, glass, earth)
When showing material symbol, do not show large areas.
