Hi Pilou,
Thanks for your feedback. "getCrvSFrame" and "RotatePts2" are from the extension package - the other nodes in the macro are taken from the stock node editor (however I have a version of the marco that uses "BBox Center" and "Rotate", which does a "similar" job).
This macro isn't really something special. The situation is that it took me quite some time to understand how to arrange cascaded orient/rotate operations in a simple way so that you can have something like a robot arm. Examples for Robot Arm like structures have been posted, before, i.e. from Karsten. But that involved quite a number of nodes where indices needed to be entered, manually. I assumed that there might be more beginners (like me) who may run into the same issue. So I thought it might be helpful to create a generic macro that makes the same job done in a simpler way.
best regards
Bernhard
