Cutting Irregular Shape into an Irregular Cylinder (plane cockpit) I've been battling with a problem for a few days, which i'm unable to resolve without creating awful topology/triangles etc. I've tried the Boolean route, but when it came to using subdiv surface / edge looping, the results were terrible due to all the triangles etc...

I've gone back to the drawing board to try and create a cleaner version, but i'm unable to figure out how to cut a cockpit (red line - see image) into the plane fuselage.  I tried subdividing into smaller squares then inset > pulling the cockpit quads down.  But this resulted in loads of triangular teeth around the edges.

Any suggestions on how to cut but retain good topology would be much appreciated!
So why don't you simply cut this part with a knife? Plus before adding edge loops you should make sure that the whole shape is good.
