I'm in the middle the Spitfire tut and I was wondering whether it was beneficial or just good practice to when wings are being 'placed' instead of attached that a hole is needed to be cut out of the fuselage?
I have had a go but found that alot of seemingly unneccessary geometry is needed to get clean edges.

As appose to this where I'll probably have to make lots of new edge loops

Could i just leave it and keep my nice clean geometry?
