+// CLASS:    MDrawData
+//
+// *****************************************************************************
+//
+// CLASS DESCRIPTION (MDrawData)
+//
+//    The MDrawData class holds geometry specific information for user
+//    defined shapes which maya does not intrinsicly know about.
+//
+//    This class is used in the draw methods of MPxSurfaceShapeUI
+//    For each draw request you must create and add a draw data object
+//    which will contain geometry specific information that you will need
+//    in the subsequent call to MPxSurfaceShapeUI::draw.
+//
+//    MDrawData contains one void* member which is a pointer to an
+//    object that you define. This object is the geometry needed to draw
+//    your shape.
+//
+//    To create draw data use the function MPxSurfaceShapeUI::getDrawData.
+//    This function takes two arguments, the first is a pointer to your
+//    geometry object, the second is the draw data being created.
+//    To add the data to a request use MDrawRequest::setDrawData.
+//
+//    Draw data is also used to carry texture information to your draw method.
+//    For materials with texture you must call MMaterial::evaluateTexture
+//    from your MPxSurfaceShapeUI::getDrawRequests method.
+//    Then in your draw method use MMaterial::applyTexture to set up the
+//    viewport to draw using the textured material.
