Pointcloud to CAD alignments

Often when making a point cloud to CAD alignment on sheet metal, the cloud don't fit (see A.JPG).

This is what I think because of the sheet metal can be wrong shape with some degree so it fit better on the opposite side.

I would like to have a CAD Controls in the alignments window (see B.JPG), so I can choose some CAD surface to fit my points (see C.JPG) or you can say as well like "helping the alignment calculation". 

Expected result (see D.JPG).
