Rhino 8, Hops 0.16.4, Compute and .NetFramework

Grasshopper Hops
1

Hello @AndyPayne
running the latest Hops configuration, it seems the whole thing fails when Rhino is running with .NetFramework, is this solvable anytime soon? since I’m trying to use Hops with Rhino.Inside Revit.

I have created a YT issue to look into this.

Thank you Andy!

@tay.othman did you explicitly set the .NET runtime to be 4.8? If so, why?

5

Hello @stevebaer
I set my Runtime to be 4.8 because I’m running it inside. Revit! and Revit is still behind!

6

That should automatically “just work”. What happens if you SetDotNetFramework to “Default” and try Rhino.Inside Revit?

I keep getting surprised, It works inside revit!
thank you @stevebaer

8

and does Hops now work under this condition?

9

yes, it works I was able to test it on a simple sphere gh referenced in a hops components inside Revit’s environment.
also the same Hops file works fine under “Default” runtime.
