Hi, I’m trying to use OpenNest components in Grasshopper, but I’m not getting any results. The components don’t show any errors, but nothing changes in the Rhino viewport.
Can anyone help me with this?
you wont get help without providing files
From screenshot i see that you use srf components, try to use Sheets and Geometry components:
Of course, the file is attached.
Furniture-Automation.gh (17.4 KB)
Furniture-Automation.gh (17.4 KB)
Your script reads excel sheet. Noone can run this script without the excel sheet…
I thought the issue was with the components, so I didn’t send the Excel file. Here it is.

Dear Petras,
I saw the picture you sent, I guess it was the same project as mine. I still do not understand what the problem is. I also checked the ‘.NetCore’ details but there was no problem either.
I should mention that I downloaded the plugins from the Rhino’s “Project Manager” section because I can not open the link you share on the “https://www.food4rhino.com/en/app/opennest#downloads_list”.
Could it be a problem?
Thank you for your time.

What each component shows when you connect a panel to each of them?
Package manager is the only way to install OpenNest.
Did you try any of the examples?
These are the results of the outputs.
I’ve tried both examples you send. It was the same. There were no mistakes but they did not work either.

Hmm very strange. Does OpenNest1 and OpenNestCollision components work?
Examples files of them.
Is there any error message on rhino command line?
Do you use latest Rhino8?
OpenNest1 and OpenNestCollision are the same. There are no errors with the components, but nothing is showing up in the Rhino viewport. Rhino 8 is not the latest version; could this be the problem?
Is OpenNest2 only for Windows 11?
Any message in rhino command line?
Yes, probably possible to compile to other versions too.
I see this message when I open the file.

And polylines and borders output anything from the sheets and geometry components?
They have values, but when I connect them to the OpenNest2 input, it fails. I also tried passing them through a curve component, but the error persists.

Dear Petras,
I’ve found the problem. The properties you see in the image should be disabled. I don’t know if it causes any harm, but my problem was solved by unchecking that box.
