How to Design a Sierpinski Tetrahedron Using 3D CAD Software

Fractal geometry is a fascinating branch of mathematics that finds applications in art, design, and computer graphics. One of the most iconic fractal structures is the Sierpinski Tetrahedron, a recursive 3D shape made up of smaller tetrahedrons arranged in a self-replicating pattern. Using SelfCAD, a powerful and accessible 3D modeling tool, designers can create this intricate structure with precision and ease. This article will guide you through the step-by-step process of designing a Sierpinski Tetrahedron in SelfCAD, exploring techniques such as shape duplication, scaling, and positioning. By mastering this process, designers can gain a deeper understanding of fractal modeling while enhancing their 3D design skills.
