I have been conducting a series of in-class exercises in the freshmen year architectural geometry course, focusing on Euclidean constructions, basic drawing and transformation commands, introductory fractals, regular and semi-regular tessellations, patterns, modeling, and unrolling polyhedra using Rhinoceros software. Junior architects, interior designers, industrial designers, and enthusiasts from other disciplines can benefit from these concise drawing exercises. Thus, I will publish two exercises every week on my blog and other platforms. So, here is today’s exercise Polygon Spiral.

In the sixth exercise, we expand our CAD skills by adding new functionality. You’ve already learned the basic drawing and transformation commands in Rhino. Now, you’ll focus on using the object-snapping tools, which are crucial for any CAD software. Snapping your cursor to specific points in the drawing is essential to ensure precision at any zoom level. So, Rhino provides several snapping options, allowing you to snap accurately to endpoints, midpoints, or perpendicular points on a curve. However, you don’t need these tools for every drawing, and they can sometimes create confusion, which is why you have the option to toggle them on or off. In the polygon spiral exercise, you can also study the layers, line types, thicknesses, and precise printing options. These are important for learning to produce quality outputs.

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