lofted surface? I think it is a little work but you should be able to get it with 2 planes and loft surface and then mirror it or create 3 planes(2 on each end and the 3rd in the middle) and loft surface. You can use 3D sketch for guide curves. This would be my approach to begin with and workaround. I made a small testpart to show if that is what you wanted.
Good luck. :D
Thanks! That is just what I wanted.
There is a Feature called, 'spline on Surface'.
You can use that to create the expected windshield outline.
