I am running a hybrid sequential simulation that consists of a lens system and a cover window in front of the lens. The cover window is modeled as a non-sequential object, and I have set up its parameters accordingly. To create the non-sequential object, I used an STP file. However, I noticed that a stand surface is always required for non-sequential objects within the sequential system. Unfortunately, this stand surface is positioned too far away, which prevents me from moving the cover window closer to the lens system.
