base_face是为指定的一个面,下面的这个错误我怀疑是不是指定的这个面本身就有问题？？？？
这个问题很急，希望高手帮忙！！

error = UF_MODL_ask_face_uv_minmax( base_face,uvs ); // 得到指定面的U和V
/*printf("Error from Asking uv minmax = %i\n",error);*/
   if ( error != 0 )
   {
      UF_OBJ_set_blank_status( steels[cnt],UF_OBJ_NOT_BLANKED );          /* Unblank the steel */
//UF_get_fail_message ( error,message );
      sprintf( box_message,"Error Asking UV Parameters for Steel %s - steel skipped",object_name );
      uc1601( box_message,1 );
      goto donewithsteel;
   }

   params[0] = ( uvs[0] + uvs[1] ) / 2;                   /* Set params to find face midpoint */
   params[1] = ( uvs[2] + uvs[3] ) / 2;

   error = UF_MODL_ask_face_props( base_face,params,face_point,       /* Get face properties */
                                    vec1,junk,junk,junk,vec3,junk );
//printf("Error from Asking face properties = %i\n",error);
printf("Face point = X%lf  Y%lf  Z%lf\n",face_point[0],face_point[1],face_point[2]);    // 值是：X242.970668  Y1387.556782  Z645.000000
