ModelDoc2::FeatureChamfer -- What is it?

Anyone have any idea what this function is meant to do? Thedocs say the following about the parameters:

=========
Width
Width of the chamfer in meters

Angle
Angle of the chamfer

Flip
0 if angle is to be measured from the right face

1 if angle is to be measured from the left face
========


I can't divine from this what UI functionality this is meant toduplicate. Macros to create chamfer features typically use theFeatureManager::InsertFeatureChamfer function, so I'm not surewhere this function would be used.SolidworksApi macros
