what is wrong with GeomAPI_ExtremaSurfaceSurface

what is wrong with GeomAPI_ExtremaSurfaceSurface.
I found it have error when I use this class to calculate the extrema distance between a surface and a very large plan .
The segment joining the two points of the two surface seems like not perpendicular to the two surfaces!

Don't know if it's relevant here but perhaps you could trim your surfaces by some known limits (e.g. some bounding box you know your model fits into). In this case you could receive more reliable calculations.
You might want to continue analysis to find a work-around and submit a bug report to bugmaster with precise description.

Roman Lygin,

thank you ,but bounding box is not enough.
i have bound this plane into a circle which cover the projection of the other surface ,but there are still errors.
