Thank you Tracje, however I tried using that. My node has, for instance, 10 circles that represent points and that are at a certain distance. I use autotransform on the whole node of 10 circles with "setAutoScaleToScreen(true);" but what happens is that when I zoom my scene, the distance between the circles does not change. Do I need to add an autotransform for each circle?
