Hello,

I have a duct ventilation accessory, and I would like to apply a rotation to it on its axis (angle defined by the XY and Z plane)

I started a script to apply this rotation. He works.

But now we need to know the current angle to calculate the angle of rotation to apply.

This is where I’m stuck
