I am currently modelling an aerobatic aircraft for a contest and needed to make the 3d model of it. I'm stuck with that crease that appears from the edge of the canopy. How do i make it disappear? (I used Boundary surface on some 3d sketches)
As far as I can tell by looking at image, Have you added tangency? If not please use tangent with face and select the prior face with it.
Many times when I was stuck at such places I used to trim the whole surface and then create a loft surface with tangency to fix.
A few time Fill surface helped, but many more times the result was disastrous.
