Hey @user2583,

Thanks for posting here. There are more people and a better chance of getting help here than on the old Grasshopper forum.

Your screenshot shows that OpenNest is installed. How did you install it?

Can you please run the attached grasshopper definition and let me know where it’s being loaded from?

The error is perhaps you use curves or open polylines, whereas project component only works with closed plolylines.

Attach the file.

I install it from food4rhino and copied files to libraries folder then restart rhino that’s all

it’s loaded from this path.
C:\Users\compu fast\AppData\Roaming\Grasshopper\Libraries\OpenNest.gha

and thanks for the replay.

yes, I use curves. is that the problem?

Make sure that you unzipped all of the files into the same directory as OpenNest.gha and that they’re all unblocked. Alternatively, close Rhino, remove the OpenNest files from the Libraries folder and then install using the package manager (_PackageManager command).

Hi -

Then you probably have a firewall or antivirus blocking your access. You’ll have to make sure that you can access yak.rhino3d.com.

If you use the package manager (which you haven’t), you don’t have to worry about that. When you download OpenNest from Food4Rhino, you save a zip file on your machine somewhere. Select that zip file in Windows Explorer, right-click and pick Properties. In the Properties dialog, check the Unblock box:

Then unpack the zip file.

Hi -

There are pros and cons but I find the package manager easy to use. Other than that, some plug-ins are only available on Food4Rhino (or other channels), while some are only available through the package manager.
As for solving your issue with getting access, other than what I wrote about the firewall and possibly antivirus, I’m afraid I can’t help.

Ok, this seems to work, it was just the installation problem.
