Curve Inner Edges of an Mesh (Not the outer edges which I can use bevel on) I am quite new to blender and am trying to model a futuristic delta wing spacecraft/plane. I am having trouble creating a cockpit because I couldn't find how to curve edges. Please note I am not looking for how to bevel the edges but curve the side of an object.



I want to note that I started by making two curves then converting them to meshes. Then I joined the meshes. And last I connected the vertices. If there is a better way to do what I am doing please tell me.



Here are some reference images to help you understand what I am saying and the situation.





Unfortunately I don't have enough reputation to post more images. I hope you can understand what I am trying to ask. Thanks in advance.
I didnt found a precise answer but you can delete the mirror modifier then delete the vertices that are in the positions (x,y,0) axis (so you should be left with a mesh that contains vertice that are connected,) then apply a screw modifier and change axis to y. then once you have that object you can apply the screw modifier then use knife to cut through in souch a way that it would be useful to add the mirror modifier again , apply the cut.Then enable clipping in the mirror modifier and scale at x axis to get a pleasing result.Also at this point instead of scaling you can play around with the curve modifier or others modifiers like deform.If you are good in nodes you can install a plugin called sverchok and try creating the cockpit there but it can be ways harder than doing it with this way.
