How to Rotate (Solved)

Hi this is a really silly question. I have this ramp i have drawn the panels how do i rotate the panels to slop against the ramp

Hi,

Select all panels to be rotated and simply use _Rotate3D.

Use what I’ve marked in green as rotation axis, the orange point as first reference, and finally the blue point as second reference or target.

Thank you so much!
