Rhino.Inside.Revit does not load some .gha plugins


Hi there,

Today, I noticed that when I open Rhinoceros and Grasshopper with Rhino.Inside.Revit, some plugins fail to load. Rhinoceros shows error messages like the ones in the attached images. It seems to be a problem with .NetFramework.

However, when I open Rhino and Grasshopper normally (not with Rhino.Inside.Revit), all .gha plugins load fine.

Does anyone know how to fix this problem? I need to use some .gha plugins in RiR.

Thank you very much in advance.

Assuming you are in Revit 2025, which is runs in .NET 8.0.0 and wouldn’t be compatible with all gh plugins compiled in .Netframework.

Rhino 8 itself can be run in .Net 7 (native) or legacy 4.8, previous versions of Revit are in 4.8 (.Netframework)

Hi Japhy,

Thank you for replying. In fact I am running RiR in Revit “2024.2”.
2024.2 is not compatible either?

Thank you so much !

That would negate possibility of it being a 2025 .net 8 issue.

To troubleshoot lets isolate from potential conflicts with other Revit Addins.

another way is open an new instance of Revit by Shift+Cntl clicking here (green dot) and selecting the first option (blue dot)

Thank you so much for your reply.

I tried Running Revit without other Addins.
But still there is the same problem of .NetFrame things…
