Freeform honeycomb structures and lobel frames

Abstract

In freeform architecture and fabrication aware design, repetitive geometry is a very important contribution to the reduction of production costs. This poster addresses two closely related geometric rationalizations of freeform surfaces with repetitive elements: freeform honeycomb structures defined as torsion-free structures where the walls of cells meet at 120 degrees, and Lobel frames formed by equilateral triangles. There turns out to be an interesting duality between these two structures, and this poster discusses the geometric relation, computation, modeling as well as applications of them.
