Hello Again Kim

I now have what you sent me in my file but I need to understand how you made it work.

I think I like the option that you used with the cross product.

Where can I get the definition on what it does and how it works?

will keep playing around with what you sent until I get the understanding I need so I will know how to use it further down my project.

Again Many thanks for your help and also your quick reply

Best regards

David

Not "5*p",

 It's "0.5*pi" which means 90 degree rotation in radian.
