Surface Metrics Overview
Surface Metrics sample demonstrates  usage of
    ISurfaceMetric_KC for 
    calculation of projection of points and curves to surface of an object 
The application
The 3D point group of controls specifies coordinates of a point and its 
    projection to surface of the main object. Coordinates of the projected point are 
    updated on pressing of Calculate button 
The 3D curve group allows movement of the curve in 3D space. Turn on the 'Show 
    Local Frame' check box to see the local axes. Press Move button to perform the 
    specified movement 
When Calculate button has been pressed the applications shows projection of the 
    curve to surface of the object in blue  
See implementation, which is straightforward, for more details
