dividing nodes

Hi,

i was wondering if anyone knows a script or has an idea of how to divide a node to enable the fabrication of branching structure.

anything would be immensely helpful. I've done what i want to achieve in rhino 'manually' but there must be a more efficient way to do so in grasshopper which would also be capable of dividing more irregular branching structure. i've posted images of this below.

I basically want to CNC the ends of poles to enable them to fit together to make a branching structure from a pre-defined grasshopper geometry.

thank you,

George
