Spinning rigid objects in Kangaroo2

#1

After seeing the tutorials in Kangaroo2 for wind simulation and rigid body simulation, I was wondering if there’s a way to spin solid objects on an axis. My first stab at this using the bouncy solver finds an equilbrium, so I wanted to know if there’s a way to vary the wind/improve on this definition so that I can spin the “door” around the global y axis.

I’ve had a similar problem with trying to get things to spin.
What I’ve found best so far… (but still I don’t think is right once the part moves…


It’s a hexagonal polygon I’m spinning… top of this image I make it a part… I find the vector between successive vertices on the polygon in the lower section… then use the plane of the part from above … and a fader to keep adding an angle onto the transform…

Please tell me there’s a better way… I’d love to be able to find out from the kangaroo outputs about what forces I’m exerting on the polygon…

Here’s what I’m doing

it’s to simulate this…
