Elevation drawings, or elevations, show the vertical sur-faces of a structure. Interior elevations, discussed later inChapter 16, show interior walls. Exterior elevation draw-ings show the entire front, sides, and rear of a stmcture.In this chapter, you wiII learn how to apply the elements ofdesign to creating the exterior form of a building, includ-ing the selection of roof, window and door styles.
The term "elevation" also refers to the vertical surfacesthemselves. Designing the elevations of a structure is onlyone part of the total design process. However, the eleva-tion design reflects the part of the building that peoplesee. The entire structure may be judged by the elevations.

Relationship with theFloor PIan
Since a structure is designed from theinside out, the design of the floor plannormally precedes the design of the ele-vation. The complete design processrequires a continual relationship betweenthe elevation and the floor plan.
Flexibility is possible in the design ofelevations, even in those designed fromthe same floor plan. Once the location ofdoors, windows, and chimneys has beenestablished on the floor plan, the develop-ment of an attractive and functional eleva-tion for the structure depends on variousfactors. Roof style, overhang, grade-lineposition, and the relationship of windows,doors, and chimneys to the building llnemust be considered. Choosing a desirable
! elevation design is not an automatic
€ process that follows the floor-plan design,E but a creative process that requires
F imagination.
E The designer should keep in mind thatg only horizontal distances can be estab-&, Iished on the floor plan. However, on an
E elevation, vertical heights, such as heights
E of windows, doors, and roofs, must also be
€ shown. As these vertical heights are
E established, the appearance of the outsideE and the way that the heights affect the
$ internal functions of the building must be
E considered.

to create functional and attractive build-ing exteriors.
The principles and elements of designwere defined in Chapter 2. In this chapter,the elements of design (line, form, space,color, light, materials, and texture) areapplied to the creation of elevations. Thetotal appearance of an elevation dependson the relationship among its componentparts, such as surfaces, roofs, windows,doors, and chimneys. The balance of theseparts, the emphasis placed on variouscomponents of the elevation, the textureof the surfaces, the light, the color, and theshadow patterns all greatly affect the gen-eral appearance of an elevation.
LinesThe lines of an elevation tend to create
either a horizontal or vertical emphasis.The major horizontal lines of an elevationare the ground line, eave line, and ridgeline. If these lines are accented, theemphasis will be placed on the horizontal.If the emphasis is placed on vertical linessuch as corner posts and columns, theemphasis will be vertical. In general, a lowbuilding will usually appear longer andeven lower if the design consists mostly ofhorizontal lines. The reverse is true fortall buildings with vertical lines.
Lines should be consistent. The lines ofan elevation should appear to flowtogether as one integrated line pattern.Conti.nuing a line through an elevation fora long distance is usually better thanbreaking the line and starting it again.Rhythm can be developed \Mith lines, andlines can be repeated in various patterns.
Wtren additions are made to an existingdesign, care must be taken to ensure thatthe lines of the addition are consistent
I286 PART 4 _ BASIC ARCHITECTURAL DRAWINGS
with the established lines of the structure.The lines of the component parts of anelevation should relate to each other, andthe overall shape should reflect the basicshape of the building.
Form and SpaceLines combine to produce form and cre-
ate the geometric shape of an elevation.Elevation shapes should be balanced. Theterm "balance" refers to the symmetry ofthe elevation. Formal balance is usedextensively in colonial and period styles ofarchitecture. Informal balance is more

widely used in contemporary residentialarchitecture and in ranch and split-levelstyles. (Refer back to Chapter 2.)
Vertical space (elevation) emphasis, oraccent, can be achieved by several differ-ent devices. An area may be accented bymass, color, or material.
In addition to the elements of design,the basic architectural style of a buildingneeds to be considered when designingelevations. A building's style is moreclosely identified by the elevation designthan by any other factor.
The type of building structure must alsobe compatible with the architectural styleof the elevation. However, within basicstyles of architecture, there is consider-able flexibility in the type of structure. Fig-ure 15-1 shows the basic types ofstructures. The elevation design can bechanged to fit the building site andlor tocreate the appearance ofseveral differentarchitectural styles, as long as the basicbuilding type is consistent with that style.

Elevations should appear as one inte-gral and functional facade, rather than as
asurface in which holes have been cut forwindows and doors and other structuralcomponents. Doors, windows, and chim-ney lines should be part of a continuouspattern of the elevation and should notappear to exist alone. See Fig. 15-2.
Light and ColorAn elevation that is composed of all
light areas or all dark areas tends to beuninteresting and neutral. Some balarc--ring of light, shade, and color is desirablein most elevations. Shadow patternscan be created by depressing specificareas, using overhangs, texturing, andvarying colors. Door and window trim,columns, battens (strips covering joints),and overhangs can be used to create mostshadows.

An elevation may contain many kindsof materials, such as glass, wood,masonry, and ceramics. These must becarefully and tastefully balanced for thedesign to be effective. An elevation com-posed of too many similar materials isineffective and neutral. Likewise, an ele-vation that uses too many different mate-rials is equally objectionable. In choosingmaterials for elevations, designers shouldnot mix horizontal and vertical siding ordifferent types of masonry. If brick is theprimary masonry, brick should be usedthroughout. It should not be mixed withstone. Similarly, it is not desirable to mixdifferent types of brick or stone.
Creating ElevationsThe first step in elevation design is to
choose an architectural style. (Refer toChapter 1.) Then sketch the outline of anexterior wall showing the roof shape andthe position of doors, windows, and otherkey features such as chimneys or dormers.
Next, create a series of progressivesketches to develop an elevation design.Experiment with different roof styles, doorand window designs, siding materials forthe exterior walls, overhangs, chimneyshapes, roof materials, and trim varia-tions. Sketches can also show variousarchitectural styles derived from thesame floor plan. See Fig. 15-3.

Roof Style and TypeTo design elevations, a designer needs
to know roof styles and which style bestmatches the building's overall style. Thereare many styles of roofs. The gable, hip,flat and shed styles are the rnost popuiar.See Fig. 15-4. Other features which affectthe appearance of the roof must also beconsidered. These include the size andshape of dormers, skylights, vents, chim-neys, and cupolas. In addition to style, theoverhang size and the roof pitch {angle)must be determined during the designprocess.
Roof framing plans are subsequentlydeveloped from the basic roof design thatis developed. A roof plan shows the out-line of the top view of a roof with solidridge, valley, and chimney lines. Dashedlines represent the outline of the floorplan under the roof. Small arrows showthe slope direction. Refer again to Fig. 15-
4. (Detailed information on roof framingdrawings is presented in Chapter 30.)
GABLE ROOFS A gable is the triangularend of a building. Roofs that flt over thisarea are gabled roofs, or, more simply,gable roofs. Gable roofs are the most com-mon roof style because of their adaptabil-ity to a wide variety of architectural styles,from colonial to contemporary. They alsodrain and ventilate easily.
Variations of gable roofs include A-frames, winged, and pleated gables.A-frame roofs extend to the floor line, cre-ating continuous ceilings and walls inside.Winged gable roofs are created by extend-ing the ridge overhang further than theoverhang at the corners. See Fig. 15-5,page 290. Pleated (folded plate) roofs con-sist of a series of aligned and connectedsmall gable roofs. Refer again to Fig. 15-4.
HIP ROOFS Hip roofs provide eave-lineprotection around the entire perimeter ofa building. The hip roof overhangs shadewindows that would not be shaded at agabled end. For this reason, hip roofs arevery popular in warm climates. See Fig.15-6, page 290. Another variation of thehip roof is the Dutch hip. A Dutch hip iscreated by extending the ridge outward tomake a partial gable end at the top of thehip. Refer again to Fig. 15-4.

have the structural advantage normallygained by rafters leaning on a ridgeboard. Heavier rafters (ceiling joists) areneeded. Because of snow-load problemsin cold climates, flat roofs are most popu-lar in warm climates. See Fig. 15-7.
SHED ROOFS A shed roof is aflat roof thatis slanted. If the down slope faces south,
shed roofs are ideal for solar panels.When clerestory windows are addedbetween offsetting shed roofs, light can beprovided for the center of a building.Again, see Fig. 15-4. Many industrial build-ings use multiple shed roofs andclerestory windows in a sawtooth patternto maximize center Iight.

VAULTED ROOFS Vaulted roofs are curvedpanel roofs. They are composed of a seriesof manufactured curved panels which areerected side by side between two bearingwalls. This arrangement allows for largeropen areas since the curved constructionis structurally stable.
BERMUDA ROOFS Bermuda roofs origi-nated on the island of Bermuda in theCaribbean Sea. There the large fasciaareas characteristic of the design areused to collect rainwater. This designeffect is often used as a feature in otherareas of the world. See Fig. 15-8.
DOME AND DOME-SHAPED ROOFS As youiearned in Chapter 1, domes have beenused in architecture for centuries. Domeroofs, iike A-frames, provide both roof andwalls in one structuraiiy sound unit.

BUTTERFLY ROOFS TWo shed roofs whichslope to the center create a butterfly roof.This roof style allows for higher outsidewalls which can provide more lightACCESS.
GAMBREL ROOFS Gambrel roofs are dou-ble-pitched roofs. They are also known asbarn roofs. Gambrel roofs are the distin-guishing feature of Dutch colonial houses.They are used to create more headroomin one-and-one-half story homes.
MANSARD ROOFS Mansard roofs are dou-bie-pitched hip roofs with the outside con-structed at a very steep pitch. This type ofroof is used on French provincial homes.(Refer back to Fig. 1-9.)

Because there is no need for internal sup-port walls or columns, completely openfloor space and flexible room sizes arepossible.
The geodesic dome, developed by R.Buckminster Fuller, can be inexpensivelymass produced at relatively low cost.Actually, geodesic domes are not true"domes." They are series of triangleswhich are combined to form hexagonsand pentagons. See Fig. 15-9.
There are several restrictions toremember in designing dome structures.The use of domes for residential construc-tion restricts the design to a predeter-mined area. Working with walls that arenot plumb (exactly vertical) creates prob-
lems in fitting cabinets, fixtures, appli-ances, and furniture effectively into thedesign.
NEW TECHNOLOGY AND ROOF STYLES Thedevelopment of new building materialsand methods in molded plywood, plastics,and reinforced concrete has led to thedevelopment of many shapes of roofs. Theconoid, cylindrical parabolic, and hyper-bolic parabolic roofs are among the mostrecent designs. Again, refer to Fig. 15-4.
ROOF OVERHANG The overhang is the por-tion of the roof that projects past the out-side walls. Sufficient roof overhang shouldbe provided to afford protection from thesun, rain, and snow. See Fig. 15-10. Thelength and angle of the overhang greatlyaffects a roof's appearance and ability toprovide protection. Figure 15-11 shows
Fig. 15-10 I Effects of long and short overhangsun and rain protection.

that when the pitch is low, a larger over-hang is needed to provide protection.However, if the overhang of a high-pitchroof is extended to equal the protection ofthe low-pitch overhang, it may block theview from the building. To provide protec-tion and, at the same time, allow sufficientIight to enter the windows, slatted over-hangs may be used.
The fascia edge of an overhang does notalways need to parallel the sides of ahouse. See Fig. 15-12. The amount of over-hang is also determined by architecturalstyle. Large gable end overhangs, such asthe g' overhang shown in Fig. 15-13, mustbe supported by columns. Some gable

ROOF PITCH In designi.ng roofs, the pitchor angle of the roof must be determined.The slope is the ratio of the rise over therun. The run is the horizontal distancebetween the ridge and the outside wall.The rise is the vertical distance betweenthe top of the wall and the ridge. The runis always shown in units of tz. Therefore aslope of 6/tz means the roof rises 6" for

every 12" of run. The pitch is the ratio ofthe rise over the span. Pitch is covered inmore detail in Chapters 16 and 30.
Window StylesWindows are designed and located to
provide light, ventilation, a view, and-insome climates-heat. To accomplish thesegoals, the size, location, and shape of'eachwindow must be planned according to thefollowing guidelines:
1. Relate window lines to the elevationshape to avoid a tacked-on look, asshown in Fig. 15-24.
2. Plan window height to allow for furni-ture and built-in components that areplaced near windows. See Fig. 15-14.
3. Plan window sizes to match availablestandard sizes. Refer back to Fig. 14-13.
4. Decide which windows need to openfor ventilation and which should befixed. See Fig. 15-15.

5. Be sure each window functions fromthe inside as required.
6. Position windows to access the bestviews. Avoid window placement thatexposes undesirable views. Avoid mul-lions and muntins if they restrict views.See Fig. 15-16.
Z.In warm climates, minimize theamount of window space on the southand maxirnize north-facing windows.Do the reverse in cold climates.
B. Keep the window style consistent withthe architectural style of the house.

13. Windows that provide ventilationshould be located to capture prevailingbreezes and provide the best air circu-lation.
14. If possible, locate windows on morethan one wall in each room, to providefor the best distribution of light andventilation.

Door StylesThe style , size, and location of doors do
not have as great an effect on elevationdesign as windows. This is because of thelimited options among door sizes and fordoor locations. Usually an elevation willeither have only one door or will containno doors at all. Nevertheless, the princi-
ples of placement relative to other eleva-tion features is the same for doors as forwindows. Refer back to Fig. 15-2.
Door types fall into three main cate-gories: exterior, interior, and garagedoors. Exterior doors provide securityand visual privacy. Interior doors provideprivacy and sound control betweenrooms. Figure 15-20 shows an elevationview of the most common types of interiorand exterior doors.

Drawing ElevationsThe main features of the outside of a building are
shown on elevation drawings. Exterior elevation drawingsare orthographic representations of the exterior of astructure. These drawings are prepared to show thedesign, materials, dimensions, and final appearance ofthe structure's exterior components. In a building, thesecomponents include doors, windows, the surfaces of thesides, and the roof. Interior as well as exterior elevationdrawings are projected from floor plans. Dimensions areused to show sizes, and elevation symbols are used toindicate various features on the drawings.

Elevation ProjectionIn orthographic (multiview) proiection,
related views of an object are shown as ifthey were on a two-dimensional, flatplane. To visualize and understand ortho-graphic projection, imagine a buildingsurrounded by a transparent box, asshorm in Fig. 16-1. If you draw the outlineof the structure on the transparent planesthat make up the box, you may create sev-eral orthographic views. For example, thefront view is on the front plane, the sideview on the side plane, and the top viewon the top {horizontal) plane. If the planesof the top, bottom, and sides were hingedand swung out away from the box, asshoum in Fig. 16-2, six views of the housewould be created. Note how each view is
positioned on an orthographic drawing.Study the position of each view as itrelates to the front view The right side isto the right of the front view. The left sideis to the left, the top (roofl view is on thetop, and the bottom view is on the bottom.The rear view is placed to the left of theleft-side view since, if this view werehinged around to the back, it would fallinto this position.
Notice that the length of the front viewtop (roofl view, and bottom view areexactly the same as the length of the rearview. Notice also that the heights andalignments of the front view, right side,Ieft side, and rear view are the same.Memorize the position of these views andremember that the lengths of the front,

Purposes of Projected ElevationDrawings
Elevation drawings are used to showthe design of the finished appearance of astructure. Elevations are dravrn to anexact scale, usually the same as the floorplan. For this reason, elevations accu-rately represent all height dimensionsthat are not shown on floor plans. Thestyle of wi.ndows, doors, and siding arealso indicated on elevation drawings. Thevertical position of all horizontal planes,

such as ground lines, floor lines, ceilingIines, deck or patio lines, and roof linesare only revealed on elevation drawings.Lines below the ground line such as foun-dation and footing lines are drar,rm bydashed lines.
Only through the use of elevation draw-ings can the vertical relationship of build-ing components be visualized. Forexample, on the site plan in Fig. 16-4A,heights are shown by the contour lines.However, little height detail is apparentwithout the elevation drawing shown inFig. 16-48.

Drawing Elevations froma Floor PIan
Think of an elevation as a drawingplaced on a flat, vertical plane. Figure 16-5
shows how a vertical plane is related toand projected from a floor Plan.
OrientationFour elevations are normally projected
by extending lines outward from each wallof the floor plan. When these elevationsare classified according to their location,
CHAPTER 16 - DRAWING ELEVATIONS 303
they are called the front, rear (or back),right, and left elevation. When these ele-vations are projected on the same draw-ing sheet, the rear elevation appears to be
upside down and the right and left eleva-tions appear to rest on their sides. See
Fig. 16-6. Because of the large size of mostcombined floor plan and elevation draw-ings, and because of the need to show ele-vations as normally seen, the elevationdrawing is rotated so each elevation canbe drawn with the ground line on the bot-tom. See Fig. 16-7.

SOUTH ELEVATION(FRONT)
The north, east, south, and west com-pass points are often used to describe andlabel elevation drawings. This method ispreferred because it reduces the chanceof elevation callout error. When thismethod is used, the north arrow on thefloor plan or site plan is the key. Forexample, in Fig. 16-6, the rear elevation isfacing norbh. Therefore, the rear elevationis also the north elevation. The front ele-vation is the south elevation, the left ele-vation is the west elevation, and the rightelevation is the east elevation.
When elevations do not align exactlywith the four major compass points, asplit compass reading may be used. SeeFig. 16-8.

Elevations and ConstructionFraming elevations show the position,
type, and size of members needed forconstructing the framework of a struc-ture. When these are not PrePared,builders relv solely on exterior and inte-rior elevations for the height of framingmembers. This means that precise dimen-sions on the elevation drawings are cru- icial for accurate construction. Figure 16-8 s
shows an exterior elevation drawing thatwas drawn from the floor plan shovm inFrg. l4-2O. It also shows the related eleva-tion under construction and in compietedform. Observe and match the features ofthe elevation drawing with the framingdetails and appearance of the finishedexterior. Look ahead also to Fig.22-2foranother view of the same house.
Steps in Projecting ElevationsThe major lines of an elevation drawing
are derived by proiecting vertical linesfrom the floor plan to the elevation draw-ing plane and measuring the position ofhorizontal lines from the ground line. To
develop an elevation drawing whichexactly reflects the features of a floorplan, refer to Fig. 16-11 and follow thesesteps:1 Using the floor plan, proiect the vertical
Lines that represent the main lines ofthe building. These lines show the over-all length or width of the building. Theyalso show the width of doors, windows,and the major parts or offsets of thebuilding.
When projecting an elevation on aCAD system, use the grid pick functionto project the major lines from the floorplan to the elevation plane. During thedrawing process, floor plans can berotated 90'to position each elevation

with the ground line on the bottom dur-ing the drawing process. Some archi-tectural software can create elevationsfrom floor plans if height dimensionsare input.
2 Measure and project hori,zontal linesthat represent the height of the groundline, footing, doors, tops and bottoms ofwindows, chimney, siding, breaks,planters, and other key features. Toeliminate the repetition of measuringeach of these lines for each elevation, asheet showing the scaled lines is oftenprepared. See Fig. 16-12.
3 Complete the basi,c elevati,on First,develop the roof elevation projection. Inorder to determine the height of theeave and ridge line, the roof slope(angle) must be established. On a high-slope roof, there is a greater distancebetween the ridge line and the eaveline than on a low-slope roof. See Fig.16-13. Pitch is the angle of the roofdescribed in terms of the ratio of therise over the span (rise,/span) described

in terms of the ratio of the rise over therun (rise,/span). Span is the horizontaldistance covered by a roof. Rise is thevertical distance. The run is alwaysexpressed in units of tz. The span is therun doubled. Therefore the span isalways expressed in units of Zq.
After the pitch is established, aslope diagram must be drawn on theelevation, as shown in Fig. 16-14. Theslope diagram is developed on theworking drawings by the drafter. Thecarpenter must work with the pitchfraction (ratio) to determine the angleof the rafters from a pitch angle table,so the ends of the rafters can be cor-rectly cut. Double the run to find thespan. The span is the distance betweenthe supports of the roof. It is a constantof z+. Place the rise over the span (24)and reduce if necessary. This fraction isused by the carpenter to determine therafter angle in degrees.
A roof elevation can be projectedfrom a roof plan. See Fig. 16-15. Notethat the end ofevery eave, and every

Elevation SymbolsSymbols are needed to clarify and sim-
plifii elevation drawings. They help todescribe the basic features of an eleva-tion. Some symbols identify door and win-dow styles and positions. Standardizedpatterns of dots, iines, and shapes showthe types of building materials used onexterior walls. These kinds of symbols onan elevation make the drawing appearmore realistic. See Fig. 16-17.
Material SymbolsMost standard architectural symbols
resemble the material they represent.However, in many cases the symbol doesnot show the exact appearance of thematerial. For example, the symbol forbrick does not include all the iines shownin a pictorial drawing. Refer again to Fig.16-17. Representing brick on an elevationdrawing exactly as it appears is a long,laborious, and unnecessary process. Many

elevation symbols appear as if the mater-ial were viewed from a distance.
When using a CAD system, elevationsymbols such as doors and windows canbe stored in symbol libraries. For exam-ple, the material symbols function can beused to add siding material symbols onelevation surfaces. See Fig. 16-18.

3 Add ceiling lines and floor lines to giveeach wall its specified height.
4 Project lines directly from the key loca-tions on the floor plan to each elevationdrawing. This includes cabinets, appli-ances, windows, and other details.Projecting the interior elevation in this
manner is appropriate for accurate draw-ing, but results in an elevation drawn onits side or upside down. Therefore, inte-rior elevation drawings, like exterior ele-vations, are not left in the position as theywere originally projected from the floorplans. Interior elevations are repositionedso that each floor line appears on the bot-tom as a room would normally be viewed.
Once the features of the wall are pro-jected to the elevation from the floor plan,dimensions, instructional notes, and addi-tional features can be added to the draw-ing. See Fig. 16-26.
Interior elevations provide a greatamount of detail: the height of all cabi-nets, shelving, ledges, railings, waII lamps,fixtures, valances, mirrors, chair rails,electrical outlets, switches, landings, andstair profiIes.

Elevation DimensioningThe vertical (height) dimensions are as
important on elevation drawings as hori-zontal (width and length) dimensions areon floor plans. Many dimensions on eleva-tion drawings show the vertical distancefrom a datum line. The datum line is a ref-erence that remains constant. Sea level iscommonly used as the datum or basic ref-erence for many drawings. However, anygiven line can be conveniently used as abase or datum line for vertical reference.
Dimensions on elevation drawingsshow height above the ground line. Theyalso show the vertical distance from the

Standards and Guidelines forDimensioning
Elevation dimensions must conform tobasic standards to ensure consistency ofinterpretation. The arrows on the eleva-tion drawing in Fig. 16-29 show the appli-cations of the following guidelines forelevation dimensioning:
1. Vertical elevation dimensions shouldbe read from the right side of thedrawing.
2. Leveis to be dimensioned should belabeled with a note, abbreviation, orterm.

Types of DimensionsTWo types of elevation dimensions are
used, framing dimensions and finisheddimensions. Framing dimensions showthe actual distances between framingmembers. This is the most commonmethod and is preferred by most builders.To avoid an accumulation of measuringerrors, framing member dimensions areoften dimensioned to their centers.

and exterior elevations, but dimensionedonly on the exterior elevation drawings.Many other features or components-suchas cabinets, shelving, counters, ledges,railings, wall lamps, switches and recepta-cies-can only be dimensioned on interiorelevations. See Fig. 16-32.
Landscape on ElevationDrawings
Creating a Realistic DrawingElevation drawings, although accurate
in every detail, do not show exactly howthe building will appear when it is com-plete and landscaped. The reason is thatelevation drawings do not show the posi-tion of trees, shrubbery, and other land-scape features that would be part of thetotal elevation design. Adding these land-scape features to the elevation drawingcreates a more realistic drawing or ren-dering of the house.
Finished dimensions show the actualvertical distances between finished fea-tures, such as from the finished floor tofrnished ceiling levels. These two types ofdimensions should not be alternatelyused on the same drawing, unless theexception is clearly noted. A note on eachdrawing or set of drawings should indi-cate which method is used.
Interior vs. Exterior DimensioningFeatures that are shared by an interior
and exterior wall, such as doors and win-dows, are usually shown on both interior

Steps for Making LandscapedElevations
An elevation drawing is converted intoa landscape elevation drawing in severalbasic steps, as shovm in Fig. 16-35. Aftermaterial symbols are placed on the eleva-tion, the positions of trees and shrubs areadded. The elevation lines within the out-lines of the trees and shrubs are erased,and details are added. Finally, shade linesare added to trees, windows, roof over-hangs, chimneys, and other major projec-tions of the house.

A. Before landscape rendering.
B. After landscape rendering.
Figure 16-33 shows some of the advan-tages of adding rendered landscape fea-tures to an elevation drawing. Theelevation shoum in Fig. 16-33,4., whendimensioned, would be adequate for con-struction purposes. However, the illustra-tion shown in Fig. 16-338 more closelyresembles the final appearance of thehouse. Dimensions and hidden iines areomitted.
When landscape features are added toelevations, the drawings function as pre-sentation drawings. These presentationdrawings are prepared only to interpretthe final appearance of the building pri-marily to clients. They are not used forconstruction purposes. See Fig. 16-34.
