Drawning Lecture 2

Week 2 Lecture Overview

• Recorded lecture introducing concepts for the week.

• Focus on representing 3D objects in 2D drawings.

• Building on Week 1 activity related to sketching fruit.

• Introduction to the concept of projection in drawing.

• Preparation for further drawing techniques in Week 3 (plan, section, elevation drawings).

Methods of 2D Representation

• There are three main methods to represent 3D objects in 2D:

  • Orthographic Projections

    • Used in this unit for accurate measurements.

    • Captures height, width, and depth using flat representations.

  • Oblique Projections

    • Discussed later in the course.

  • Perspective Drawings

    • Not used in this unit as measurements cannot be accurately taken from them.

    • Distortion happens, making it hard to draw or measure.

Projection Types Explained

Orthographic Projections

• Different views such as:

  • Plans: Top-down view.

  • Elevations: Side views.

  • Sections: Cuts through the object showing interior.

• Projections are made using parallel lines from the object to achieve accurate measurements.

Oblique Projections

• Objects are projected straight up from the base.

• Easy to measure and distinguish features.

• Helps visualize details without distortion as seen in perspective.

Drawing Techniques

Starting with Plans

• Begin with a plan to outline the base and main features of the object.

• Importance of correct line drawing and measurement to avoid distortion.

Drawing Sections and Elevations

• Elevation: View from the exterior, shows how height affects the perception of a building.

• Section: A cut through the building showing internal structure and design elements.

• Importance of recognizing how line weights and textures can communicate different materials and structural elements.

Specific Examples Discussed

Villa Savoye by Le Corbusier

• Introduction to modernism in architecture.

• Analyze the plan for:

  • Columns represented as solid black circles.

  • Walls and internal structures indicated by varying line weights.

Basrad Church by Jorn Utzon

• Interior vs. exterior complexity demonstrated in plans, sections, and elevations.

• Emphasis on pathways and areas of movement within the plan.

• Geometric designs contrasting in section due to curvatures.

Villa Maria by Alvar Aalto

• Show complexity through varied materials and textures in plans.

• Understanding the significance of wall thickness and different line weights.

Jewish Museum, Berlin by Liebeskind

• Complex geometries captured in plans, making sections and elevations challenging.

• Using dimensions and offsets to clarify the building's shape in the drawing.

Conclusion and Next Steps

• Recap of the importance of using plans as a foundation for sections and elevations.

• Encouragement to practice these skills and bring any questions to class.

• Reminder that understanding these forms of representation is crucial for future architectural work.
