PATH ASTERISM_Series

A parametric joint / node research project while at Autodesk's Pier 9 Artit in Residence program. I explored a number of node and joinery types including this cross stub tenon for wood-to-3D print and TIG welded stainless steel 3D prints. Some of the optimization and sorting of the nodes was done with the help of Peteinarelis Alexandros. This is an ongoing project!

    Thanks for the answer, I'm not sure I get the part:

     the interface between the two would have to happen quite far from the node itself.

    Could you elaborate and tell us more about the geometric solution behind the smooth node geometry?

    I was using the 'exo wireframe' component which solves/smooths for a holistic set of interconnected input lines/geometries. You have the option of setting the end and beginning radius for each strut, though because of smoothing, the number of, and the differing lengths of various struts, the 'smoothed node' can be a bit 'uneven' meaning some of the end conditions were fine while others tapered or were smoothed farther away from the node itself. The smoothing was overall pretty good, but getting it to meet up perfectly(in terms of matching the tube diameter) at a specified distance from the intersection was less consistent that's all. 

    Hope that explains it better?

    oh, I didn't know the exoskeleton plugin existed. thanks for englightening me :-)
