Re: point on a linear element

Hi Yang Lee...

   Just project the point on to the element by using
mdlProject_perpendicular function, then you will get the point on the
element(ptOnElm).

Now check the distance(distBetweenPts) between two points ie from
input point (inPt) to point on the element (ptOnElm), if
distance(distBetweenPts) is zero input point lies on the element.
