Architectural

Presentations

Presentation drawings are those we typically think of when the term

Òdesign drawingÓ is used or mentioned. These drawings describe a design

proposal in a graphic manner intended to persuade an audience of its

value. The audience may be a client, a committee, or merely someone

browsing for an idea. Whether produced to assist the clientÕs

imagination or to obtain a commission, either privately or through a

competition, presentation drawings should communicate as clearly and

accurately as possible the three-dimensional qualities of a design.

Although the drawings that comprise a presentation may be excellent

two-dimensional graphics worthy of an exhibition, they are merely tools

for communicating a design idea, never ends in themselves.

ARCHITECTURAL PRESENTATIONS

172 / ARCHITECTURAL GRAPHICS

Unless presentation drawings are comprehensible and

persuasiveÑtheir conventions understood and their

substance meaningfulÑa presentation will be weak and

ineffective. An effective presentation, however, also

possess important collective characteristics.

Point of View

Be clear about design intent. A presentation should

communicate the central idea or concept of a design

scheme. Graphic diagrams and text are effective means

of articulating and clarifying the essential aspects of a

design scheme, especially when they are visually related

to the more common types of design drawing.

Efficiency

Be economical. An effective presentation employs

economy of means, utilizing only what is necessary to

communicate an idea. If any of the graphic elements

of a presentation become distracting and ends in

themselves, the intent and purpose of the presentation

are obscured.

Clarity

Be articulate. At a minimum, presentation drawings

should explain a design clearly and in enough detail so

that viewers unfamiliar with it will be able to understand

the design proposal. Eliminate unintended distractions,

such as those caused by ambiguous figure-ground

relationships or inappropriate groupings of drawings. Too

often, we are blind to these glitches, because we know

what we want to communicate and therefore cannot read

our own work in an objective manner.

Accuracy

Avoid presenting distorted or incorrect information.

Presentation drawings should accurately simulate a

possible reality and the consequences of future actions

so that the decisions made based on the information

presented are sound and reasonable.

Unity

Be organized. In an effective presentation, no one

segment is inconsistent with or detracts from the

whole. Unity, not to be confused with uniformity,

depends on:

¥ A logical and comprehensive arrangement of

integrated graphic and verbal information;

¥ A synthesis of format, scale, medium, and

technique appropriate to the design as well as to

the place and audience for which the presentation

is intended.

Continuity

Each segment of a presentation should relate to

what precedes it and what follows, reinforcing all

the other segments of the presentation.

The principles of unity and continuity are mutually

self-supporting; one cannot be achieved without the

other. The factors that produce one invariably

reinforce the other. At the same time, however, we

can bring into focus the central idea of a design

through the placement and pacing of the major and

supporting elements of the presentation.

PRESENTATION ELEMENTS

174 / ARCHITECTURAL GRAPHICS

A single drawing cannot fully explain a design. Only

through a coordinated presentation of related drawings

can the three-dimensional form and character of a design

be communicated. To explain and clarify aspects that are

beyond the capability of the drawings, we resort to

diagrams, graphic symbols, titles, and text. In any design

presentation, therefore, we should carefully plan the

sequence and arrangement of all of the following

elements:

Graphic Images

¥ Drawings

¥ Diagrams

Graphic Symbols

¥ North arrows

¥ Graphic scales

Lettering

¥ Titles

¥ Legends

¥ Text

All of the above elements have properties that must be

considered in composing a visually balanced presentation:

¥ Shape, size, tonal value, and visual weight

¥ Placement, direction, and interval

PRESENTATION SEQUENCE

ARCHITECTURAL PRESENTATIONS / 175

We generally read design presentations from

left to right and from top to bottom. Slide

and computerized presentations involve a

sequence in time. In either case, the subject

matter presented should progress in

sequence from small-scale to large-scale

graphic information, and from the general or

contextual view to the specific.

¥ Area Plan / Site Plan

¥ Perspective Views

¥ Paraline Views

¥ Details

¥ Building Sections ¥ Building Elevations

¥ Floor Plans

¥ Diagrams

DRAWING RELATIONSHIPS

176 / ARCHITECTURAL GRAPHICS

The sequence and alignment of the drawings should

reinforce their projected relationships.

¥ Orient all plans in a similar manner. Whenever

possible, orient plan drawings with north up or

upward on the sheet.

¥ The first- or ground-floor plan may extend out

to include adjacent outdoor spaces and features,

such as courtyards, landscaping, and garden

structures.

¥ Relate floor plans of multistory buildings either

vertically above one another, or horizontally side

by side.

¥ Vertical arrangements should begin with the

lowest floor level at the bottom and rise to the

highest level at the top.

¥ Horizontal arrangements should begin with the

lowest floor level on the left and proceed to the

upper levels on the right.

¥ Whenever possible, relate floor plans along their

longer dimensions.

¥ Arrange building elevations either vertically or

horizontally, correlating them whenever possible

to corresponding floor plans.

¥ Likewise, organize building sections either

vertically or horizontally and relate them

whenever possible to the floor plans or building

elevations.

¥ Lay out a related series of paraline drawings

vertically or horizontally. When each drawing

successively builds on the preceding one, work

from the bottom up or proceed from left to right.

¥ Relate paraline and perspective drawings as

directly as possible to the plan drawing that best

shows their context or point of view.

¥ Include people and furniture to show the scale

and use of spaces in all drawings.

FORMING VISUAL SETS

ARCHITECTURAL PRESENTATIONS / 177

Design drawings are usually presented as a related set or group of

figures. Typical examples include a series of floor plans for a multistory

building or a sequence of building elevations. The spacing and alignment

of these individual drawings, as well as similarity of shape and

treatment, are the key factors in determining whether we read these

drawings as a set of related information or as individual figures.

¥ Use white space and alignment to reinforce the

organization of the graphic and verbal information

of a presentation. Do not fill up white space unless

absolutely necessary.

¥ If you want two drawings to be read as individual

figures, the space between them should be equal to

the space between each drawing and the nearest

edge of the field.

¥ Moving the two drawings closer together causes

them to be read as a related group.

¥ If you move the drawings closer still, they will

appear to be a single view rather than two related

but individual views.

¥ Properly related drawings that form a visual set

can themselves define the edge of a field for

another drawing or set of figures.

¥ Lines can serve to separate as well as to unify, to

emphasize, and to outline. Avoid using lines,

however, when spacing or alignment can achieve the

same purpose.

¥ Boxes can establish a field within a larger field or

within the boundaries of the sheet or board. Be

aware, however, that using too many frames can

establish ambiguous figure-ground relationships.

¥ A tonal value can be used to define a field within a

large field. A darker background for an elevation

drawing, for example, can merge with a section

drawing. The foreground for a perspective can

become the field for a plan view of the building.

GRAPHIC SYMBOLS

178 / ARCHITECTURAL GRAPHICS

Graphic symbols help the viewer identify the various

aspects and features of a drawing or presentation.

¥ North arrows indicate the major compass points on

architectural plans so that the viewer is able to grasp

the orientation of a building and its site.

¥ Graphic scales are graduated lines or bars representing

proportionate size. These scales are especially useful

because they remain proportional when a drawing is

enlarged or reduced.

¥ Section arrows indicate the location of section cuts on

plan drawings.

Graphic symbols rely on conventions to convey

information. To be easily recognizable and readable, keep

them simple and cleanÑfree of extraneous detail and

stylistic flourishes. In enhancing the clarity and

readability of a presentation, these devices also become

important elements in the overall composition of a

drawing or presentation. The impact of graphic symbols

and lettering depends on their size, visual weight, and

placement.

Size

The size of a graphic symbol should be in proportion to the

scale of the drawing and readable from the anticipated

viewing distance.

Visual Weight

The size and tonal value of a graphic symbol determines its

visual weight. If a large symbol or typeface is required for

readability but a low value is mandatory for a balanced

composition, then use an outline symbol or letter style.

Placement

Place graphic symbols as close as possible to the drawing

to which they refer. Whenever possible, use spacing and

alignment instead of boxes or frames to form visual sets

of information.

LETTERING

ARCHITECTURAL PRESENTATIONS / 179

A wealth of well-designed and legible typefaces is available in the form

of pressure-sensitive, dry-transfer sheets as well as in computerized

typography. You should therefore spend time on the appropriate

selection and use of fonts rather than attempt to design new ones.

¥ The most important characteristic of lettering

is legibility.

¥ The character of the typeface we use should be

appropriate to the design being presented and

not detract from the drawings themselves.

¥ Serifs enhance the recognition and readability

of letter forms. Avoid mixing serif and nonserif

typefaces in a single title or body of text.

¥ Lowercase lettering is appropriate if executed

consistently throughout a presentation.

¥ The differences among lowercase characters

are more distinct, making lowercase lettering

generally easier to read than text composed of

all capitals.

¥ Determine the range of lettering sizes by

judging the distance from which the audience

will view the presentation. Keep in mind that we

may read different portions of a

presentationÑproject overviews, diagrams,

details, text, and so onÑat different

distances.

¥ Space letters by optically equalizing the areas

between the letter forms rather than by

mechanically measuring the distance between

the extremities of each letter.

¥ Word processing and page layout programs

have made the spacing of letters and lines of

type much easier.

HELVETICA IS A VERY LEGIBLE TYPEFACE.

HELVETICA NARROW

is useful when space is tight.

TIMES IS A CLASSIC EXAMPLE OF A

TYPEFACE WITH SERIFS.

PALATINO has broader proportions

than Times.

Serifs enhance the recognition and readability of letter forms.

Lowercase lettering is particularly appropriate for

bodies of text.

LETTERING

180 / ARCHITECTURAL GRAPHICS

¥ Guidelines are required to control the height and line

spacing of handlettering. The maximum size for a

handlettering is 3/16 of an inch. Beyond this size, the

strokes require a width beyond what a pen or pencil is

capable of producing.

¥ Use a small triangle to maintain the verticality of vertical

lettering strokes. The visual movement of slanted lettering

can be distracting in a rectilinear drawing scheme.

¥ Maintain similar proportions among the characters of a

title or line of text.

¥ Everyone inevitably develops an individual style of

handlettering. The most important characteristics of a

lettering style are readability and consistency in both

style and spacing.

LETTERING

ARCHITECTURAL PRESENTATIONS / 181

Lettering in a design presentation should be carefully

integrated into the composition of drawings on each

sheet or board.

Drawing Titles

Arrange titles and graphic symbols into visual sets

that identify and explain the contents of a drawing.

By convention, we always place titles directly below a

drawing. In this position, titles can help stabilize

drawing fields, especially irregularly shaped ones.

Use symmetrical layouts with symmetrical drawings

and designs. In all other cases, it is usually easier to

justifyÑalign verticallyÑa drawing title with

either the drawing itself or its field.

Text

Organize text into visual sets of information and

relate these sets directly to the portion of the

drawing to which they refer. The line spacing of text

should be more than one-half of the letter height

used, but no more than the letter height itself. The

space between blocks of text should be equal to or

greater than the height of two lines of text.

Project Title

The project title and associated information should

relate to the overall sheet or board, not to any single

drawing within the field of the panel.

PRESENTATION FORMATS

182 / ARCHITECTURAL GRAPHICS

A set of related drawings may be laid out in a vertical,

horizontal, or grid format. In planning the layout for a

presentation, first identify the essential relationships you

want to achieve. Then we use a storyboard or small-scale

mockup of the presentation to explore alternative drawing

arrangements, alignments, and spacing prior to beginning

the final presentation drawings.

¥ Remember to explore potential relationships between the

sheets or panels.

¥ Maintain horizontal continuity across sheets with a

ground line or by the alignment of drawing titles.

¥ Do not include unnecessary dimensions or employ borders

and title blocks; we reserve these conventions for

construction or working drawings.

¥ When a presentation consists of more than one sheet or

board, identify each panel by a number. This information

should be in the same relative position on each panel.

¥ If the panels of a presentation are to be displayed in a

specific manner, you can use more graphic means to

identify the relative position of each panel in the display.

Digital Formatting

Drawing and publishing programs give us the ability to

try out different ways to arrange the elements of a

presentation. However, because what we see on a monitor

does not necessarily match the output from a printer or

plotter, a trial layout should always be printed or plotted

to ensure that the results are satisfactory.

Digital technology has also introduced the elements

of time and motion into architectural presentations....
