Donut pattern

[Joe26 (Joe)]

Hi I build this pattern in Alias studio tools, but I’m trying to learn grasshopper. Can anyone help me get started. It will be much appreciated. The surface donut shape and pattern are brought in to Rhino as IGES files. The pattern is all close at the seams and edges, but is floating inside the donut shape because as you can see in the images all corners dont touch a normal grid floor from plan view?
Any help getting this started will mean so much…

Regards,
Joe

Hello
welcome to the forum. Your question are far from clear. You ask for Grasshopper but you seem to have problem with the IGES export ?

I see nothing except some geometry!
If you want better help it could be good you read that.

It is quite easy to do that in Grasshopper. So why exporting from IGES ?

Hexagons on surface : Is there a tool that outputs nice hexagons?

Dear community I tried some plugins to put hexagons on a surface with a seam. I tried lunchbox, ngon. I didn’t try Paneling tool. These tools have problems or the seams (lunchbox, or too much points (polyline with 9 points for ngon plugin), not hexagons at the ends, or too much distorsion … As I need quite nice hexagons I developed a little tool 2 hours work). You just have to put the number of hexagons on a ring and say where is the seam (U or V). [image] Did I miss an existing tool ? M…

Hi Laurent, thx for the replies. Sorry for the delayed replied. I have been doing other projects as well. here I will be attaching everything I have tried so far. Still having issues but making progress. I tried a few things. I have figure out a few things by trial and error too. I installed the Lunchbox pluggin and couldn’t get it to work to do anything I want it.

in this picture I can’t get the shape to be continuous all around. Don’t know how?

in this pic there are gaps between the shapes that I’m trying to avoid.

my pattern shape edges are 3mm all the way around but I can’t get the hexagonal 2D grid to be 3mm all the way around. I thought if I could do that all the edges in the pattern would line up.
probably with Lunchbox it can be done but I don’t know. I will attach all files and even my original Alias Studio tools as an .iges file so you could see my original intent. Any help will be greatly appreciated…and thx once again

“1 month later”… Are you familiar with the concept of “context switching overhead”? Long delays require review and re-starting a task. This is an imposition on those trying to help you.

Addressing the Detrimental Effects of Context Switching with DevOps

The overhead incurred by a context switch managing the process of storing and restoring state negatively impacts operating system and application performance. […]

From a human workforce perspective, context switching is the process of stopping work in one project and picking it back up after performing a different task on a different project. Just like computing systems, human team members often incur overhead when context switching between multiple projects. […]

Prompt replies reduce the overhead of context switching.

Hi Joseph, I totally understand your concern, and apologizes for the late replies, but I also have two jobs and freelance projects going on. I also have a family and trying to learn something new in the process. The little time I get comes and goes fast. Not making excuses just explaining my situation. Have a great day.

Hi Laurent, thx for the replied and thx for sharing. I will check your nodes and see if there is something I could try, but like I said is not a full donut. If you look at the last images, I shared you could see that the pattern comes to an end at the top it doesn’t roll in same as the bottom. I know is very complicated to control from an edge but that is what I’m trying to achieve. Thx once again for the replied and trying things on your end, much appreciated.
