A “hypar” is short for a hyperbolic paraboloid, a double-curved, saddle-shaped surface often used in architecture and structural design due to its unique geometric properties. It is a ruled surface, meaning it can be constructed entirely with straight lines, despite its curved appearance. In this short tutorial video, I am building a beginner-level 3D pattern that resembles the hypar surface. This is a basic drawing exercise to control the viewport and place primitive objects precisely. Thus, more advanced tutorials would include the real parametric surface of a hyperbolic paraboloid, made by scripting or Grasshopper. So, here is the modeling cylinder hypar video:

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. I will publish exercises every week on my blog and other platforms. So, today’s exercise is modeling cylinder hypar. I hope you benefit from these exercises. Please stay tuned for more exercises and tutorials.

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