At their base level, lattices are repeating structures. Spoked wheels and trusses are examples of lattice-based objects that have a basic topology that repeats either consistently or with a degree of variation.
Dealing with lattices in computer aided design has always been tricky, but the pace of technological advancement has given designers increasingly powerful tools that enable latices to be built and manipulated with astonishing ease. Put simply, they’re now a joy to work with.
