How to specify adjustment surface for Surface Thickness tolerancing using Python ZOS-API

Question

Is there a way to specify an adjustment surface relative to another surface for thickness variation. I am developing a custom script to perturb surface #1 thickness and I would like to specify surface #6 as the adjustment surface (I am not sure if calling surface #6 as compensator surface is correct)

Basically, I would like to implement the functionality of the TTHI command using ZOS-API.

TTHI command: Surface #, Adjustment Surface # (Tolerance on thickness or position in lens units, with optional adjusted)

Thanks - A

Hi @Asuku!Settingsurface 6 as the compensator is not quite the same functionality as a surface thickness adjustment, as a compensator is optimized vs a criterion. A surface thickness adjustmentis just taking an extra thickness and affecting it to another surface.I think you should be able to read the variation of the thickness, right? Then it can be appliedto your surface 6 for example. We have some solves like position solves but I am not sure it is needed here.

Hi Sandrine, yes that is exactly what I would like to do. I would like to set Surface# 6 as adjustment.

So, you suggest that I manually change thickness on Surface6 based on the Δ change in Surface #1?
