Window and rotation

Hi everyone!

I have to create a bow-window with a singular glazing face and after I have to calculate the Daylight Factor, using Honeybee.

I've created two boxs in Grasshopper, one of which can rotate. I've created an unic mass zone and after I've used a glazing creator.

My window appeares on my little box, but when I rotate it, the window disappeares (so I can't run the simulation.)

I share some images to make clear.

Hoping you could help me. Thanks!!
