I suggest isolating loft operations to just the pertinent geometry.  Extend the geometry as needed to create a surface large enough to slice a solid made from more basic (Box) primitives.

That's entirely up to you.  No one is suggesting you leave.

I refined the geometry and the 3D solid looks better.



I still have two places on the solid which should be put in order.
Is the lofting bad approach for such body? I see that only one surface is not good: all surfaces located in one plane are OK. The flow of lines on curved surface seems to be "drunk".

Here is the copy of the drawing:

I thank for each answer.

Yes, I uploaded the copy of the drawing in one of the previous posts (at 20:57). I will check if I can open it.

P.S. I checked: it is possible to open the drawing.

If I use each third profile solid looks much better. Also the geometry is not accurate as it can be.

If I avoid critical part of the solid it looks fine.
Now must find the way how to close the gaps.

Thank you John for your answer. Here is the file with the drawing:

In the meantime I found out that the closed profiles are not of the same type. There are polylines (green), splines (yellow) and 3D polylines (blue).


In the next step I added one profile on the place where the solid has discontinuity in the form. The first blue line, lower. Also, I started to loft from the top (!?) and the form was better.
On two places I have the irregularity in the surface. I don't know yet, how to solve this problem.
