Hi ! You should try to retrieve your node positions by using the python methods. parent1.ypos() instead of parent1['xpos'].value()
#Example3 ypos by itself parent3 = nuke.nodes.Dot() parent3.setXYpos(400,0) child3 = nuke.nodes.Dot() child3.setInput(0,parent3) child3.setXYpos(parent3.xpos(), parent3.ypos()+100)
