Kangaroo mechanical rigging Daniel Piker videos

I’m following Daniel’s pikker video’s about assemblies in Kangaroo in Vimeo.
I have a doubt, in the video’s, the assemblies are like floating Ik’s , without any part anchored to a static, fixed in position piece.
How to setup this??

Thanks a lot in advance

Hi @user124

If you need to fix any parts of your assembly in place (or just lock certain translation or rotation axes), you can use the Support component.
The only required input for this component is the Frame identifying the rigid body you want to anchor.

You have the option of setting a Target frame, for if you want to lock it somewhere different to its original location, but if you leave this input blank it locks it in place.
With the target frame you can also move it during simulation from Grasshopper, with a slider for example.

Here’s a simple example definition:
