Hello
After thinking from me ...
I wonder if the easiest for me that would not be quite simply to ask you as I had done for the tower of ELA4 to make me a dll.
It was papyref who advised me to ask you, what I had done.
I remember giving you the coordinates, angles and axes of rotation as well as the numbers of groups to animate, and you made me the necessary dll.
And it works very well.
What do you think ?
