Project Breps onto Breps as Surfaces

Beginner in Grasshopper modelling here:

I have two sets of objects - one group that represents rooms and another group that represents windows in that room.

The “room” and “window” objects are offset from each other in the 3D space and what I need to do is to “project” these windows onto the nearest face of the room object and create surfaces.

I have managed to do that for one room with one window, but I have a little diffuculties to do that for several rooms/windows at once with my limited GH knowledge.

Does anyone have any tips for me?
