Changing curve direction fails

Hi everyone,

I was wondering if someone can help me with this.

After exploding a brep and taking the edges, the 

curves were not in the same direction. So I flipped the

curve and lofted them to recreate the brep. But I noticed

that the curves were flipped again after lofting.
I need the curves to match for later operations

(brep is a imported obj file from maya, transformed into

polysurface - if that means anything..)

What can be done to solve this?

Thank you very much,
Ana
