Week 02 — Computer-Aided Design
Week Reflection
This week was especially interesting, enjoyable, and challenging. Exploring the possibilities of digital modeling to achieve organic forms proved to be far more complex than it initially seemed. I began by experimenting with simple and more rigid geometries, exploring radial structures and modular repetitions. These initial explorations helped me understand how curves and surfaces behave within the digital environment.
The process became an intentional exploration of the available tools to achieve the form I was seeking. I tested different operations and combinations to create smoother transitions and more natural curvatures. After multiple iterations, I developed a petal form with an organic character that conveys lightness, movement, and sensitivity. The model was then translated into 2D vector geometry to evaluate its fabrication feasibility and organize the components required for production. This step revealed how three-dimensional form must be simplified and structured for digital cutting processes.
Finally, rendering the model allowed me to evaluate materiality, depth, and the interaction of light with curved surfaces, helping to assess the aesthetic presence of the object before physical fabrication. This process demonstrated that digital design is not linear: it requires exploration, iteration, and a continuous dialogue between form, technique, and perception.

Design and Fabrication Workflow
1. Conceptual Geometry Exploration
The process began with the exploration of forms inspired by natural structures, particularly the radial organization of flower petals and leaves.
The exploration focused on:
- radial symmetry
- modular repetition
- layered structures
- opening and closing possibilities
Sketching helped reveal how a simple form can evolve into a dynamic system.
2. 3D Modeling and Fabrication-Oriented Design
The explored geometries were translated into the digital environment using Rhinoceros 3D, where surfaces and volumes were developed while evaluating fabrication feasibility.
During this phase:
- base curves and radial axes were defined
- surfaces were generated using operations such as loft and sweep
- proportions and thicknesses were evaluated
- tolerances and joints were considered
- the model was divided into manufacturable components
- formal variations were explored considering assembly and movement
After modeling the individual petal, several tests were performed to replicate and arrange the element radially. Using the tools like Polar Array function in Rhinoceros, the petal was duplicated and distributed around a central axis to explore symmetry, density, and spatial balance.
Different quantities and rotation angles were evaluated to understand how repetition influences the perception of movement and volume. This process allowed the form to evolve from a single component into a cohesive radial system, reinforcing both the organic character and the potential mechanical behavior of the structure.
3. 2D Vector Preparation (Rhino → Illustrator)
The geometries were exported from Rhino and refined in Adobe Illustrator to prepare them for fabrication.
The preparation included:
- cleaning duplicated lines
- organizing layers for cutting and engraving
- adjusting line weights
- optimizing tool paths
4. Visualization and Rendering (KeyShot)
The 3D model was exported to KeyShot to generate realistic visualizations that helped evaluate form, materiality, and perception.
This stage included:
- applying materials to simulate real finishes
- exploring lighting to emphasize volume and depth
- analyzing how light interacts with curved surfaces
- producing renderings to communicate the design
Reflection
This week provided insight into how an idea evolves from hand sketching to a digital model prepared for fabrication and visualization. Iteration was essential to move from rigid geometries toward more expressive organic forms.
