Hi Nicolas,

Having forward and backward designs match can be tricky with Coordinate Breaks and tilts. If the Reverse Elements tool does not work, it may be useful to use the Make Double Pass tool and then try to manually reverse signs starting at the second half, then removing the initial surfaces. This can be tedious, but if the tool to reverse the surfaces doesn’t produce the right answer, then some manual adjustment will be needed.

I’m sorry if I didn’t get at the point you were looking to address. From the question, it sounded like you mainly wanted to know how to make the tilts on a Coordinate Break match up with the tilts on a Tilted surface, which requires some adjustments because of their differing methods. The screenshot I posted shows how to use Optimization to get the NORX,Y,Z operands for different surfaces to match, namely by showing that the starting Tilted surface and the ending post Coordinate Break surfaces are oriented the same but with slightly different numbers for the rotation. The operands on lines 5-7 provide the direction cosines of the old Image surface, but it is lines 1-3 that have weight to them and are thus targeted to values read off from 5-7.

 In your case, you initially displayed a CB right before the final surface, with a sole purpose to tilt the image plane along one or more axes. The Tilted surface used as the Object matches those coordinates, but in your case you would then go ahead and remove the CB before the image so it is not parallel to the Object. I left them both there for verification purposes.

I hope this helps clarify what I meant while answering your question.
