Is it possible to pass an element (like a cube) from one person to another?
If there is such a way, where can I find it in the program?
Have you tried using the Task Simulation Builder (TSB). Here I would use the following steps:
Human 1 GET object
Human 1 PUT object in a location for the next human to GET (ex. hold it out at arms length)
Human 2 GET object
...at the end, Human 2 will be holding the object and can now use/move/work with it.
