Hello all: How can I pivot surf0 and surf1 as a group shown below at an arbitrary point in Z such that the incident ray at surf2=0°?
I would like to pivot the group in Z such that the exit ray from surf1 is normal incident to surf2
This article shows how an optical element can be pivoted about any point in space, but it is not clear how to add coordinate breaks prior to surf0.

Thanks-Asuku
