In computer-aided design (CAD), a polyline is a series (or a chain) of straight lines. Each straight section of a polyline is a “segment,” and the points where the segments connect are “vertices.” If a polyline’s starting and ending vertices coincide, it is a “closed polyline” or a “polygon”. If they do not, the polyline is classified as an “open polyline.” Polylines can be planar (2D) or 3D. The Gosper curve, named after Bill Gosper, also known as the Peano-Gosper Curve and the Flowsnake is a space-filling curve similar to the Dragon Curve or the Hilbert Curve. In this post I explain the basic drawing method of the unit curve of this fractal, naming it as drawing Gosper unit.

In this video series, I present various in-class exercises I led in a freshman-year Architectural Geometry course. With Rhinoceros software, we study Euclidean constructions, basic drawing and transformation commands, fundamental fractals, regular and semi-regular tessellations, patterns, modeling techniques, and unrolling polyhedra. These short drawing exercises also offer value to junior-level architects, interior designers, industrial designers, and enthusiasts from other fields. I will share weekly exercises on my blog and other platforms. Here is the tutorial video: drawing Gosper unit:
