but I cant make it work with the Hinge tool.
Could anybody tell me how to make this 2 triangles fold as I show in this screenshot?
Below are the grasshopper definition I've been trying to do following the Kangaroo basics video, and the two triangles 3dm file.
Thanks…
ed various mesh and surface intersect components, but figured I may as well ask if someone can point me in the right direction. Thanks in advance.
The image below attempts to illustrate my goal:

aver (though not as ugly in my example file, I hope), in grasshopper. Typically I would do this in rhino with a network surface, or perhaps a loose loft with a lot of cross sections.
To avoid having a lot of cross sections to define, I thought I'd be smart, and use curves for loose loft in the length direction; 4 would already give me a lot of control over the surface.
However, if you can't control the orientation of the isocurves in the 'cross-section' direction, you can get an ugly, ill-defined stretched surface, typically if you go 'around a corner'. So, I added guide curves (the green ones) in the side view, that split the loft curves - so you divide the surface in smaller parts, essentially defining where cross sections are going to be.
It almost works... but it turns out, the surfaces are not quite tangent when the curvature gets bigger, as the zebra analysis pic shows. Such a shame - otherwise it was working perfectly, and a very simple way to get a parametric 'network surface' like definition in GH.
So:
1) Anyone knows why it isn't working, why my surfaces don't stay tangent, even if the loft curves of the respective surfaces are perfectly tangent (as they originate from one curve, split into several)?
2) Even better, know of a way to solve it, or at least create something similar that does work?
Thanks very much, Michiel

work just for one section curve after another, if there is a kind of a crotch(?) I have to do it seperately for each Volume and bool it later, with the Problems at the top of the thread
2. try: out of a rough mesh structure and then mesh relaxation. Problem is to inflate the mesh
no more ideas...
thank you for your help

ee circles:
It took me a while to come up with a good Fitness Function but eventually I think I managed it. As you see the result is actually pretty good, it took about 5 iterations (1~2 minutes) of the Simulated Annealing solver to get this answer. I also attached the file, though you may not be able to open it even on the most recent publicly released version.

which I understand analyses only 2 octave bands (500 Hz and 2 kHz) instead of the 8 bands (for which the STI component requires background noise.)
Or have I misunderstood this metric and the three values mean something else?
For reference / a minimal definition I have the open office example (gha and 3dm attached) which includes 20 receivers and the sti results show three values for each (see the image).
Thanks in advance Roly…
