DRAF 70
floor plans—scaling & dimensioning
floor plan is perhaps most significant architectural drawing
contains tremendous amount of information
serves as primary drawing—specialty drawings keyed from
orthographic view—seen as if horizontal cutting plane passed through it at approximately 4 ft.
some exceptions can be made
viewer is looking straight down into building
largest drawing in set—residential generally ¼ inch scale

3. floor plans—scaling & dimensioning
DRAF 70
floor plans—scaling & dimensioning
separate plan is drawn for each level in multiple level buildings
each level is aligned with one above—stairs; load-bearing walls, etc…
if building includes mezzanine/loft level, upper level plan includes lower level with an “open” label

DRAF 70
floor plans—scaling & dimensioning
in construction drawings, floor plans are drawn to scale and detailed to show:
walls
doors
windows
plumbing fixtures
appliances
stairs
cabinetry
any other built-in/freestanding features
drawn as viewed from above
doors always drawn in open position

DRAF 70
floor plans—scaling & dimensioning
lineweights & different types of lines can be used to relay information
add graphic excitement & make reading easier
minimum of 3 different weights
walls—darkest & thickest
broken/dashed lines denote items above cutting plane
upper cabinets; high windows; ceiling planes
different patterns can be used on floor plan to denote change in floor treatment

floor plans—scaling & dimensioning
drafting floor plans is more efficient if logical sequence is followed
walls…openings…doorswings… fixtures…cabinets…dimensions… symbols…necessary notes
dimension lines
drafted lighter than walls
generally done as continuous group or string of numbers along a line
extension line begins slightly away from object—extends about 1/8 inch beyond dimension line
45-degree tick marks used at junction—darker so they stand out & in consistent direction

dimension lines
usually requires 2-3 continuous dimension lines to locate all exterior walls, wall jogs, interior walls, windows, doors, & other FIXED elements

floor plans—scaling & dimensioning
dimension lines
numerals placed above and/or centered on dimension line—do not rest on dimension line so more readable
oriented to be read from base or right side of drawing
if area is too small a leader is used to point to dimensioned area

dimension lines
preferred area for dimensioning is outside the walls where possible
keeps interior uncluttered
difficult to accurately dimension most projects without some dimensions within

graphic symbols & text notation are incorporated into the plan to make it as clear as possible
room use
section cuts—pg. 114
various notes are also added to convey specific information to client or builder—keep to minimum to avoid clutter

ASSIGNMENT #3
Draft the floor plan from pg. 92 of the Kilmer text. Be sure to include:
walls
openings
doors
windows
fixtures
cabinets
dimensions
be sure to use correct line weights
DO NOT mimic changes in floor treatments—we’ll address that next week
DO NOT mimic furnishings—we’ll get to
that next week
