Adding Edge Loops Around Airplane Window

Question

I would like to add an edge loop around each one of these windows and are not 100% sure on the best way to do it even after watching some videos.

If someone could point me in the right direction that would be great. Thanks.

Answer 1

Avoid NGons, and avoid Boolean operations, you topology is not quad-dominant and you wont be able to easily add edgeloops anywhere with ngons like those around the windows. in fact you will likely have a hard time doing anything at all with your current model.

Ideally your mesh should be made primarily of faces with four sides, use Ctrl+R to add edge loops, use Ctrl+B to bevel, use E to extrude, and abuse of modifiers.

In your case I am guessing a Mirror modifier would help with symmetry, a Subdivision Surface would help with smoothing/curving, and an array might help with multiple windows.

Answer 2

you can select the faces and just use I to inset the selection, this will add loops to arbitrary geometry in a way the is relatively even.
