    (setq point_id (list (x,y,z)))
    this will store ur point or co-ordinate value.
    (setq sset (ssget "c" point_id point_id (list (cons 0 "lwpolyline"))))
    this will create a selection set for pline on that point.
    if it is not returning nil means pline is crossing from that point.
    regards
