DRAF 70 floor plans—scaling & dimensioning

1. DRAF 70 floor plans—scaling & dimensioning

2. 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. 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

4. 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

5. 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

7. DRAF 70 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

8. DRAF 70 floor plans—scaling & dimensioning • dimension lines • usually requires 2-3 continuous dimension lines to locate all exterior walls, wall jogs, interior walls, windows, doors, & other FIXED elements

9. DRAF 70 floor plans—scaling & dimensioning • dimension lines • usually requires 2-3 continuous dimension lines to locate all exterior walls, wall jogs, interior walls, windows, doors, & other FIXED elements

10. DRAF 70 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

11. DRAF 70 floor plans—scaling & dimensioning • 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

12. DRAF 70 floor plans—scaling & dimensioning • 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

13. DRAF 70 floor plans—scaling & dimensioning • 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

14. DRAF 70 floor plans—scaling & dimensioning • 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
