How to Draw Architecture in Isometric

Summary

In this video, the speaker demonstrates the process of creating an isometric drawing for a conceptual design of a cafe and residential building. Using a dot isometric system and a combination of CAD and freehand techniques, the speaker explores the design’s challenges, including ramp configuration and parking layout. Through iterative sketches, the design evolves, addressing accessibility requirements and space constraints. The speaker emphasizes the efficiency of freehand drawing for quick problem-solving before committing to detailed CAD work. The video highlights the flexibility and practical advantages of sketching in architectural design.

Takeaways

• 😀 The design is based on a conceptual cafe on the ground floor with residential units above, informed by site analysis and design parameters.
• 😀 An isometric drawing was used to refine the design, utilizing a dot isometric system and a scale of 1:200 (1 dot = 1 meter).
• 😀 The speaker starts the drawing with freehand sketches, later overlaying them on translucent paper for clarity and better visual organization.
• 😀 The ramp design is a crucial component, with the correct ratio of 1:12 (1 meter up for every 12 meters of horizontal length) for accessibility.
• 😀 Initial ramp configuration was incorrect, but testing and sketching allowed for quick revisions before committing to CAD work.
• 😀 The process includes considering practical issues such as parking space dimensions and how ramp adjustments impact the layout.
• 😀 The speaker emphasizes the value of freehand drawing over computer software (CAD, Revit, 3ds Max) for faster, more intuitive design development.
• 😀 Sketching out problems like the ramp and parking early in the process helps identify issues that would otherwise be missed in CAD or 3D modeling.
• 😀 The roof design is envisioned as a curving volume, which is more suitable for wind and sunlight orientation at the site.
• 😀 The speaker explores the possibility of adding a skylight to optimize natural lighting, considering sunlight exposure and the building's orientation.
• 😀 Iterative design, through sketching and tracing, helps clarify complex elements and refine the overall concept before moving on to more detailed drawings.

Q & A

What is the purpose of using an isometric drawing in this project?

The isometric drawing is used to investigate and visualize the design from a three-dimensional perspective. It helps refine the spatial layout and structure of the café and residential building, offering a clearer understanding of how the elements work together.

Why did the designer choose to use a dot isometric system?

The dot isometric system was chosen because it provides a clear, scalable way to create the isometric drawing. Each dot represents a 1-meter dimension, which helps maintain consistency in the drawing and aids in scaling and alignment.

What role does the translucent paper play in the design process?

The translucent paper is placed over the initial drawing to help clarify the outlines and reduce confusion. It provides a clearer view of the design, allowing the designer to add and refine details more effectively.

What mistake did the designer make in the ramp configuration, and how was it corrected?

Initially, the designer used a single flight for the ramp, which didn't meet the proper ratio for wheelchair accessibility. The correct ratio is 1:12, meaning for every 1 meter of height, the ramp should be 12 meters long. This mistake was corrected by adjusting the ramp configuration and re-sketching the design.

What does the designer mean by 'investigating the design quickly rather than using CAD'?

The designer refers to using freehand sketching as a faster way to explore different design configurations. This allows them to quickly identify issues and solutions before committing to a detailed CAD drawing, saving time and effort in the long run.

How does freehand sketching help in the design process?

Freehand sketching helps the designer to rapidly explore different options, spot design errors, and refine ideas before translating them into more time-consuming computer-generated drawings. It provides flexibility and efficiency in the early stages of the design process.

What was the issue with the parking spaces due to the ramp design?

The ramp design required additional space, which would take away from the parking spots. As a result, the designer had to reconfigure the parking layout, adjusting the number of spaces and their dimensions to accommodate the ramp while maintaining accessibility.

Why did the designer consider lowering the ground level for the building?

The designer considered lowering the ground level to make the ramp configuration more feasible and to ensure better access. However, this needed to be balanced with flood risk considerations, as the area could be prone to flooding during stormy weather.

What is the significance of the roof design in the project?

The roof design is important for both aesthetic and environmental reasons. The designer is considering a unique curving form to complement the building's overall shape and to respond to wind directions. Additionally, the roof will affect natural lighting and ventilation inside the building.

What are the key considerations for incorporating a skylight into the design?

When considering a skylight, the designer looks at factors such as the space's natural lighting needs, the roof configuration, and how to control light during different times of day. A potential skylight location is identified above the interior space, with an adjustable blinder system to manage sunlight effectively.
