// iges114.cmd
// Surface Evolver script to write IGES file for surface, using IGES
// entity type 114 which handles linear, quadratic,
// and cubic triangles (among many other types not of interest).

/*
   Assumptions: 3D soapfilm model, up to cubic model,
     not torus or symmetry group
    (use the "detorus" command if necessary to convert torus or symmetry
     to unwrapped surface, but remember that detorus alters the surface)
   Does facets only, not edges. 
   Does facets satisfying "show" criterion.
   Facet color is frontcolor on both sides.
