3D-Bspline-Surface out of given Points

[Gensys]

Hello,

First of all sorry for my bad english:)

I have read serveral forum entries but there is no acceptable solution for me now.

I have a given pointcloud which represents the half of a vehicle body and i need to generate a BSplineSurface which goes through theses points.
I have tried the ReverseEngineering-Workbench but the Surface looks very horrible.
I have tried to generate Draft.BSplines through these points and used them as a base for the Loft-Feature. This Surface looks quit good, with some defects.

Does anyone have another potential method to create a "good" surface out of this points or suggestions how i can avoid the defects in the Loft-Surface?
