To set rectangular apertures on surfaces 8 10 and 12, pickup the apertures from surface 2 (for 8 and 12) and 4 (for 10) in the surface properties window.

Set the coating on surface #10 to I.50 and surfaces #8 and #12 to AR.

Update the 3D layout

Now we have the correct setup for configuration 2; however, surfaces 7 to 12 are also present in configuration 1. To see this, change the 3D layout settings to display all configurations.

Surfaces 7 to should only be present in configuration 2 and not 1. You can use IGNR (ignore surface) operands to ignore those surfaces in configuration 1.

Insert IGNR operands for surfaces 7 to 12 and set the values in configuration 1 to "1" (ignore).
