Re: 2 questions

Right---each node has 24 (or 30, or something) rigid holes, accepting one of three types of rod end-shapes (triangle, rectangle, pentagon). The design is such that there is a great variety of constructions possible, though the angles are fixed.

I would suspect that any structure with beams long enough to bend also have beams long enough to buckle---as you note. The strongest parts of the structure were the zones with lots of nodes and lots of very short connecting segments. Those were little rocks.

Re: 2 questions

another solution(?) might be to make in the respect of the connection angles, with as many bars as possible and it HUGE enough for the "microscopic" geometry not to matter. (there are many buildings withe carved walls or arches built with rectangular bricks)

once again, the basis elements resistance to buckling would have to be ensured

good luck
