Need a little help on curve paths using sweep/loft to connect two profiles

Hello, I am trying to build an aircraft but there is a specific part where I am having trouble with how to connect two profiles with curve in between

I have tried using sweep(which has shown almost what I want but it is still not as exact as it should be)
I have tried using loft(which just makes it a straight path with no curve)

Is there a way using these two tools to make the curve?

Hi, I hope you are doing good. You have to use loft in my opinion.
A recommendation, your aircraft is symmetrical, you should model only half, then in the end a mirror will do the rest.
The loft must be made with several profiles, and with a condition of tangency so that it maintains a smooth transition.
Remember to model guide curves to achieve a good transition between the profiles, and here an important point, make sure that each guide curve intersects the profiles, if you do not place the match it will give you a lot of headaches. The loft is an excellent tool, I prefer not to model the piece for you, so that you can practice over and over again until you master it perfectly.

Best Regards!!!

Hi! I believe you are trying to reverse-engineer a model airplane. I don't think you will get a good design by basing off the section sketches. You may get close, but you will run into issues very quickly. The model will not be editable easily. I think you should study the model's design intent and try to find the logical features to recreate the geometry. Ignore the detail features first and start with a simple shape. Add the detail features gradually. This is how feature-based parametric solid modeling should work.

Many thanks!
