Rebuild the geometry into closed brep

Hi all,

I am trying to rebuild the geometry for closed brep, in which I am using contour and loft and it is fine for the geometry without any hole. But when I do it for the geometry which has a hole, it is totally failed. Could anyone give me some advice?

Many thanks,
