algorithmic modeling for Rhino


I am trying to use the K2 Engineering package. I already have problems with the example files – there is always an error showing up (see screenshot in german), which says the object of the typ „supportgoal“ can’t be converted to KangarooSolver.IGoal.

It shows up for any example (not only for supportgoal also for cablegoal etc). I am using the most recent version of Kangaroo2 which can be downloaded from food4rhino.

It would be great if you could help  me out!

Thanks in advance,

Hey I had exactly the same problem. I solved it by replacing all the file in the grasshopper folder from a computer which doesn't have this problem. I think the reason could be that, the embedded kangaroo 2 in Rhino 6 conflicts with the kangaroo 2 I installed. Try it

Hi All,

Is anyone else experiencing the same issue?

I'm using Rhino 6, tried to re-install Kangaroo and Kangaroo 2 but with no luck.

Marie Pa, did you manage to find a solution?
