Error using Exoskeleton

Hello everyone,

I am trying to thicken the lines of the shell generated using Kangaroo. I am using the plugin Exoskeleton. However, I am unable to use it because of some error that I cant understand how to get rid of. The error reads: “Solution exception: Object reference not set to an intsance of an object.” It occurs when I use the Division slider. I would be extremely grateful if someone could help. Thank you.

Any help please?

Hi @kazim2,

Exoskeleton is designed to work with arbitrary topologies of lines, but when the lines have a mesh structure, as they do in your file, there are some simpler approaches.
Here’s one way using the skeleton fattener component from here. (14.4 KB)

Cleaning tree, removing duplicate lines and reducing end radius below 0.8 give some results also…

Hello Daniel,

Thank you so much for such a quick reply. This was exactly what I wanted.

I am sorry to ask extremely basic questions , but I am only a beginner in Grasshopper. Could you please just take a minute to clarify something, regarding the script above, in which you added a few components in order to use the Fatten component. Is this correct that the Kangaroo Solver gives the output as a group of lines and a mesh, so you used ‘‘Bang’’ to separate mesh from the group of lines, and then extracted the mesh edges to fatten them? You could have also used the lines output (0;1) from ‘‘Bang’’ and input into the Fatten component directly to achieve the same result, right?

Hello Daniel, is there a way to thicken the lines non-uniformly? I mean, the same line varying in thickness along its length.
