Introducing 'Exoskeleton' - A wireframe thickening tool

A collaborative effort by David Stasiuk and Daniel Piker, Exoskeleton brings simple wireframe thickening to Grasshopper. You input a network of lines, and it turns them into a solid

(without the heavy calculation of a Boolean intersection of many pipes and spheres).


The input line networks can have any topology, and need not form closed polygons or volumes, so could come from algorithms such as DLA, leaf venation, or Woolly threads.


The resulting meshes are ideal for 3d printing and further processing, such as subdivision with WeaverBird and relaxation with Kangaroo.


There are settings for the thickness of the struts, node sizes, and whether to leave openings at nodes with only one connected line.


The approach we used is loosely based on the one described in the paper Solidifying Wireframes by Ergun Akleman et al.


Thanks to Giulio Piacentino for helpful discussion in the development of this idea, for WeaverBird, and the GHA wizard, to Mateusz Zwierzycki for convex-hull ideas, and Kristoffer Josefsson for helpful discussion.
