The invention is directed to a method for creating a parametric surface symmetric with respect to a given symmetry operation (20). The invention method: (i) identifies a mesh pattern (15a); (ii) creates a base mesh (15s) from the mesh pattern, according to a symmetry operation; (iii) subdivides the base mesh, at a given order, into a subdivided mesh defining elementary faces; and (iv) forms the parametric surface (16s) according to said faces. The base mesh is symmetric with respect to the symmetry operation such as a reflection symmetry. The invention further concerns computer program product and systems implementing the method according to the invention.
