It's not the same than this...
Put your object on the X Axe
Make a first rotation around X of any ° wanted
then result with a second rotation around Z of 45 ° ?

Hi Pilou,
no the block needs to be on the 45 degree axis when rotated.

So Maybe with this Orient Node before rotation we can rotate anything on its own axe
(defined by 2 points XYZ (Top / Bottom)

Not yet tested but that must maybe work :)

Following is just one point (Bottom)

Hi Pilou,
by adding a pivot line and using the getCrvSFrame works see photo.
Cheers

Excellent! Bravo! So the simulation of the Transform / Rotation / Rotate Axis
More simple than my 2 points Top Bottom :) (that i have never found! )
