DRAF 70floor 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


•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


•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


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



•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


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


•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


•graphic symbols & text notation are incorporated into the plan to make it as clear as possible

•room use•section cuts—pg. 114•interior & exterior elevations—pg. 115


ASSIGNMENT #3Draft 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
