How to get the coordinate of a bendline in a sheet metal?

Hi there,

I get the startpoint and endpoint of a sketchline of a OneBendFeatureData used OneBendFeatureData's FlatPatternSketchSegment property.

But the coordinate of startpoint and endpoint has been translated into a xy plane. I want to know how to get the startpoint's original coordinate of the sketchline in a OneBendFeatureData or how to get the translation between the origianl one's and the new one's?
