This paper investigated a simple geodesic line search on triangular mesh surface and a modified sub-plane on the surface. A partial adjustment and element redirection of sub-plane of extracted elements series and substituting alternative nodal point were proposed for the geodesic search with modification of sub-plane. This search technique is very simple enough to attain the geodesic line without difficult mathematical or computational method.
