6_2 THREE POINTS TRUSS (OCTET TRUSS)
October 11, 2009
This is a similar example of space truss using triangles. It is also useful to generate triangle surface panelings on any surfaces.
The logic is the same with 4-Points Truss. But it is a little complicated because it is coming from rectangular grids using ‘mid points’.

Hi,
I posted this at the four points truss before, but it should be here…
is it possible that there is something wrong in the tutorial of the script?
at 8.1 the false/true pattern seems to block everything…
I need this to work urgently, please advise
The Cull information on the tutorial is right. One thing I missed on tutorial is “flatten”. As I said, you should make them “flatten” at the input of those Cull components. I updated the tutorials about where it should be “flatten”. Thanks for your comments.

Ah nice
looks like that’s it!
I still have some minor problems in my grid, and I have another question for you.
I’m missing 2 grid lines in my grid plus some strange lines at the beginnen of my script, and secondly I would like to alter the height of my truss as the U or V lines get closer together, cause that’s a problem with my design.
I have a loft that get’s thinner in the middle so the truss seems compressed there
reducing the height locally occording to the (inverse) of the distance of the grid points or lines.
Could you help me with that?
I would like to use that in my project but I have to present on thuesday.
Just let me know if you have the time so let me know if not cause then I’ll move on like I have it now, can’t afford to lose time.
Thanks anyway!
PS here are some pictures of my design and problem:

Hello HK,
I find your blog and its content very useful, and this is a topic of great interest for me,
Just going through the tutorial for your 3 point truss, Having a bit of a difficulty going through the tutorial definition posted, in the tutorial at (8-2-1-1 Shift, 8-2-1-2Shift L: End( E)) the connections actually differ from posted image.
and at (12 Ln, 13Ln) this where the definition starts falling apart, just not getting the lines as intended even after “flattening” the Cull inputs.
Need your Help if you can.
Major Thanks, and keep up the good work!!
Kind regards,
Christopher
