Geodesic Intersections

Hey all,I've been doing some work with free-form grid-shells using the geodesic components from the latest releases of g-hopper and I was wondering if anyone else has run into the same hurdles. After…Continue

Does anybody have an elegant solution for converting a 39 paths of 26 items into 39 paths of comma-separated, single-line strings of 26 items?i.e. instead of:68.28666.35763.527...i would…Continue

Hi Patrick,
I ll be taking the Rhinoscript workshop in London in May with David Rutten...
In terms of book if you completed the Grasshopper Primer then have a look at this conversation:

Thanks so much for the help, and especially the explanation! Just further proof that I really need to learn more about C# and other similar tools.
The only problem with that particular method is that it sacrifices the data tree structure. The…

Hi Patrick
Grasshopper isn't able to find the intersections due to the tolerance of the curves created by the Geodesic function. If you relax the acceptable tolerance considered acceptable for an intersection to twice that used by the Geodesic…

Thanks Arthur. I appreciate the help. Also, could you recommend a good introduction to VB Script in Grasshopper?

Hi Patrick i tried applying it again with my form and it didn t work either i will need to check the script it might work differently on the new version of GH.
Arthur Mani replied to Patrick Delorey's discussion 'Geodesic Intersections'
Hi Patrick,
I saw your comment and tried applying the script to your rhino model but couldn't make it work.
The only difference with the model i was working on and yours is that you have kinks at the base and i was working with a curved…

Thanks Mårten. I had seen that discussion previously, and modeled the grid shell method off what Arthur was working with. Still, the problem lies specifically with the intersecting points. Interestingly, I've also heard that the problems…

Hi,
In this thread http://www.grasshopper3d.com/forum/topics/geodesic-dome Arthur Mamou-Mani and Jon Mirtschin describe som techniques for free form geodesic structures (scroll down a bit). Check out some interesting stuff by Jon Mirtschin at his…
Geodesic Intersections
Hey all,I've been doing some work with free-form grid-shells using the geodesic components from the latest releases of g-hopper and I was wondering if anyone else has run into the same hurdles. After creating the grid shell curves on the surface, I can't seem to intersect them, no matter what I try.But, if I redraw the same curves with a closest point on surface and curve on surface, and flatten only ONE of the curve lists, they intersect just fine. Any thoughts on this?Also, does anyone have…See More

Hello Arthur,
Nice work with the gridshells. I've been looking into them as well for a project (see sample files) that I'm doing with some help from Mark Cabrinha.
I've patterned the basic geodesic curve setup after your earlier…
