algorithmic modeling for Rhino
Exoskeleton is a free plug-in for creating meshes. It is currently comprised of two components: Exo Wireframe and Cytoskeleton.
Exoskeleton remains a work in progress, and as bugs are fixed and new components and features introduced, updates will be placed here. Furthermore, Exoskeleton is an open-source library.
Download the most recent version here: Exoskeleton2_150904.zip
This has been updated to also include Plankton version 0.3.4

Thanks to Will Pearson, for his work on Plankton and who also has given some invaluable contributions to Exoskeleton in terms of project organisation. Thanks also to Giulio Piacentino for Weaverbird, and for general knowledge and support, and Mateusz Zwierzycki for the same, as well as for sharing his code for convex hulls, which although not used explicitly here, was very helpful in many regards for the development of Exoskeleton.

Hi Harrison-
Yes it does...you can find a more detailed explanation of the features here: http://www.grasshopper3d.com/profiles/blogs/exoskeleton-cytoskeleto...
One other issue that has come to my attention is if two struts are at too close an angle to each other, the component may return an "object reference not set to an instance of an object" error. I will try to include a test for this in an upcoming release.
Tudor-
I'm not sure if I know what you mean exactly, but I am open to treating engulfed struts differently. One approach I had thought of would be to simply extract offending struts from the solution and give the component a warning message that would show the indices of the failing elements. Another, more complex approach, would be to collapse the ends of offending struts into a "super node"...but this would make the component run quite a bit heavier, particularly if there were several failures in a try, and one fix could cause another failure, etc.
Does this new version fix the bug which results in (seemingly) random mesh vertices to be placed at the origin (i.e., [0,0,0])?
Just thinking out loud here,
could it for example treat an engulfed line as if it would be an endpoint, so for example take its midpoint instead of the line? Not quie sure if it makes sense. Other then that seems to work just fine!
Thanks again!
