In this video series, I present a variety of in-class exercises from my first-year architectural geometry course. Using Rhinoceros software, we delve into Euclidean constructions, basic drawing and transformation commands, introductory fractals, regular and semi-regular tessellations, patterns, modeling, and unrolling polyhedra. These concise drawing exercises benefit junior architects, interior designers, industrial designers, and enthusiasts from other disciplines. So, I’ll be sharing two exercises each week on my blog and other platforms. Here is today’s exercise:  Fractal Tree.

Today’s architectural geometry exercise involves creating the famous fractal tree curves. Up until now, we’ve focused on mastering basic CAD commands and their precise applications. In previous exercises, we explored concepts like drawing, transformation, and presentation. Also, we experimented with layers, line thickness, line types, and creating PDF printouts. This time, we’ll be introducing a special transformation command called Orient. To illustrate its use, we’ll experiment with drawing a fractal tree, a system that exhibits self-similarity. Starting with a simple fork shape made of just three lines, we’ll use the Orient command to generate the rest of the fractal. Once you’ve completed the exercise, feel free to experiment with different angles and line lengths to see how they affect the final pattern.

The software used in this course is Rhinoceros 3d (www.rhino3d.com).
