How to make a correct transition between a chosen window and unit floor plan?

Hi,
I have an issue with transition between chosen window and floor plan.
When I choose unit and click to see its blueprint, the unit plan appears from the middle of the building. How can I place the floor plane to be attached to the chosen window?


How I can manage the correct blueprint position in case when I use the same floor plan for different units?
Please see attached Max files.
File "Unit 4"is a floor plan for Unit 8 in GSTower file.
