Hello,
If you put your mouse over the "Orient Point" input the tooltip will tell you "One locally defined value...".
I just set the point by right-clicking the input and choosing "Set one point". You then need to decide in the Rhino command line between referencing an existing point or setting a new coordinate.
You can embed referenced data in input by right-clicking and "Internalize". "Extract parameter" instead makes a separate node with your point component, in that example.
Best,
Johannes
