how can i fix loft order problem

hello,

I have a structure that i want to model with loft order (with planes and sketches) but i have a trouble after defining planes and sketches

As you can see from the pictures the trace of the body is not good and it deviates from its path in some places and despite of creation a lot of planes to improve this but it does not work.

what should i do?

thank you.
