Ted, its more than enough to see for me, THANK YOU A LOT! For displaying the nodes I did it very difficult: I've taken a screenshot of the white coloured shape in wireframe mode, cropped it and powerclipped it to the shape. Its not very different from my usual work process, because all my meshfills are powerclipped. I am using simple forms like retangles to work with meshfill (its much easier to get control over the nodes and the subdivision)
