* @param    oLine       Output  output those lines
* @param    iShape      Input   the known shape
* @param    iFaceParts  Input   the faceparts
* @param    oSubshape   Output  the output subshape, namely, the line is represented by a VO_Shape
* @param    partIdx     Input   which part is it
* @return   void
