Project geometry onto surface with box morph issue


I have traced a window pattern and then brought the curves into GH to offset them in and create window frame and glass. After that I have tried to project this pattern onto a surface in order to create a curtain wall from this window pattern, however when projecting the geometry with box morph onto the surface it’s changed a lot.
Can anyone have a look to see what might be the issue here?
My goal is to create the pattern (see image 2) and make it work like in image 1.
Thanks a lot!
