Hello Berhard,

please check this files. You have to use the nodeeditor extensions for that (http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.750). Copy the included files under nodes\extensions and restart MoI. I have used a line to evaluate the rotation points and named all parts, so you can use getByName.

Have a nice day
Karsten

p.s.: Don't forget the file in libs.
