I can’t know for sure but is there also some missing geometry in that file? (not internalized brep and/or points?)
I don’t have much of a clue how to use Kangaroo but have learned quite a bit trying to answer this question by adapting code posted two days ago by @DanielPiker in this thread:
I haven’t succeeded yet but I’ve learned one thing about Kangaroo that drives me mad! In my ignorance, I’ve apparently defined constraints that are impossible to resolve, so Kangaroo goes into an infinite loop and there is NOTHING I can do to regain control, short of closing Rhino. SO VERY ANNOYING!!!
