AcDbRegion::getAreaProp() arguments

[Anonymous]

Hi All,

void get_area_prop()

{

    AcDbVoidPtrArray curveSegments,
regions;

    AcDbRegion::createFromCurves(curveSegments,
regions);

    AcGePoint3d origin;
   
AcGeVector3d xAxis, yAxis;

   
pRegion->getAreaProp(origin, xAxis, yAxis,
perimeter,
                         
            area, centroid,
momInertia,
prodInertia,
                                      prinMoments,
prinAxes,
radiiGyration,
                                      extentsLow,
extentsHigh);

}

face=Arial>
the
arguments origin, xAxis, yAxis are input arguments

what
is the best way to get the right values?

Thanx in
advance,
