Hey @arkdev2021!
Yes, the Vector from the green rectangle will indeed be a new one if it has changed! When the red rectangle (Set: NewVector) is executed (that’s the white line!) it does the math behind it necessary. The execution line determines activity, if you want to save a variable for use later you need to set it as a separate variable (like “Old Vector”).
All of the math is executed each time the white line is activated on the “Set New Vector”.
