Hi Sanat, The way I would tackle the task would be to write a ClinderIntersector class along the lines of the existing osgUtil::LineSegmentIntersector. The only major difference would be how you do the intersection tests with the bounding spheres, and bounding boxes of the nodes during the IntersectionVisitor traversal, and the intersection tests of the cylinder against the geometry data found in the Drawable leaves.
