Hi Pilou,
Regarding the point input to ScaleUVW:
For example, with your .nod file:
Place a physical MoI point at say (-5, -5, 0 ), for a reference marker.
Wire a point node, set to ( -5, -5, 0 ), to the pink input to ScaleUVW.
Place a circle at the origin, Top View, say radius 0.5.
Have slider vary from 0 to 10.
Select the circle, and Update Selected node.
Run the node.
Vary the slider.
Slider at zero places the circle at ( -5,-5, 0 ) with radius of zero.
Slider set to 1 leaves the circle at the origin, with radius 0.5.
Slider at 2 places the circle at ( 5, 5, 0 ) with radius of 1.
Slider at 3 places the circle at ( 10, 10, 0 ) with radius of 1.5.
etc.
