For wide angle system, it can be interesting to visualize the position and the size of a real entrance pupil in different field angles. This macro will compute with real ray tracing real entrance pupil information for different field angles. It then adds the entrance pupil as a dummy surface and each “field” entrance pupil is defined into a configuration. 
The macro assumes axial-symmetric, only y field and the field angle in object is positive. Ray-Aiming should be turned on to correctly run this macro. It may only work with field type Angle and Object Height.

How to use:  Just run the macro, and open 3D Layout with showing central field and all configs.
