Architectural Visual Communication

Introduction

  • Course Title: Architectural Visual Communication (AGraphics1)

  • Institution: Holy Angel University School of Engineering & Architecture

  • Prepared by: Ar. Noemie D. Ng

  • Academic Year: 1st Semester, Curriculum 2018-2019

Program Outcomes (PO)

  • Outcome (a): Create architectural solutions by applying knowledge in:

    • History

    • Theory

    • Planning

    • Building technology and utilities

    • Structural concepts

    • Professional practice

  • Outcome (I): Communicate effectively, orally and in writing, using English or Filipino

Learning Output (Weeks 9 to 11)

  • Apply orthographic/axonometrical projections, line values, lettering, and dimensioning through:

    • Creating floor plans

    • Designing roof plans

    • Drafting elevations and sections

Architectural Drafting Conventions

Objective

  • Discuss elements such as line types, symbols, letters, and notes in architectural drawings.

Key Terms

  • Line types include:

    • Border lines

    • Hidden object lines

    • Construction lines

    • Dimension lines

    • Poché, leader lines, and more

The Line

  • Fundamental tool of graphic communication

    • Varies in weights and types, each representing different meanings

  • Line attributes include:

    • Long, short, straight, curved, thick, thin, etc.

Line Quality

  • Critical to have excellent line quality

    • All lines should typically be black

    • Must be consistent and properly thick to convey their importance

Line Weight

  • Definition: Line weight refers to the thickness of lines

  • Thicker lines attract attention first

  • Vary line weights according to drawing scale and figure hierarchy

  • Recommended pen sizes:

    • 0.25–0.90 mm

Lines and Line Quality

  • Guidelines or Construction Lines:

    • Initial lines drawn with light pencil leads (4H to 6H)

    • Temporary and should be easily erasable

Line Types

  • Different line types represent various concepts in architectural drawing:

    • Border Lines: Define drawing margins

    • Bold Lines: Represent primary objects like walls

    • Medium Lines: Secondary objects such as furniture

    • Light Lines: Action lines, dimension lines

Lettering

Integration in Design Presentation

  • Lettering should be carefully integrated, clearly arranged, and aligned with the drawing for clarity.

  • Standard Heights:

    • Main Titles: 8-10 mm

    • Subtitles: 6-8 mm

    • Notes and dimensions: 3-4 mm

Architectural Drawing Presentations

  • Presentation drawings communicate design proposals visually to persuade the audience of their value.

Effective Presentation Characteristics

  • Point of view: Clear design intent

  • Efficiency: Use only necessary elements

  • Clarity: Present information clearly

Components of Architectural Drawing Presentations

  • A coordinated presentation of related drawings enhances understanding of a design's three-dimensional form.

    • Diagrams, graphic symbols, titles, and text are essential components

Site Development Plans

  • A site plan illustrates a building’s location and orientation on a plot and describes features such as boundaries, topography, and existing constructions.

  • Orientation: Plans should ideally have north directed upwards

Elevations

  • An elevation provides an orthographic view of a structure, highlighting its external appearance and defining its silhouette.

  • Characteristics include the use of tonal values to indicate depth.

Sections

  • A section reveals an object as if cut by a plane, important for understanding internal structure details.

  • Guidelines for creating sections include cutting through significant spaces and avoiding freestanding columns.
