Grasshopper component error

[sebastian.lindholm]

Hi Egidijus,

It seems to be because of the fact that Rhino 8 uses .NET core rather than .NET framework. Check this post on how to remedy the situation:

Grasshopper (Rhino 7) Inside Tekla (Version 2021 SP9) error

Hi, thanks for reporting. The Grasshopper Component will use the newest version of Rhino it can find that’s not WIP, so it will switch to use the newly released final version of Rhino 8 if you’ve got that installed. The problem is that Rhino 8 uses .NET 7 per default rather than the .NET Framework, which doesn’t seem to work with Tekla. To get the Tekla-Grasshopper link to work from within Grasshopper with Rhino 8, the fix as per the article is to use the SetDotNetRuntime command and set it…

Cheers,
