【讨论】UF_MODL_trim_body

Fields2003

extern UFUNEXPORT int UF_MODL_trim_body(
tag_t target_body ,/* <I>
                   Target body to be trimmed.
                   */
tag_t tool_tag ,/* <I>
                Tag of face, datum plane, or plane to be used for trim.
                */
int direction_flag ,/* <I>
                    0 = Accept default direction
                    1 = Reverse direction
                    */
tag_t * trim_feature  /* <O>
                      Resultant trim_feature identifier tag
                      */
);
以上为此函数的声明,照理说这是最简单的函数了,可我怎么就是出错,我要实现的目标如下图所示,源程序如下,请高手指点:
//============================[1] Create a sphere====================    
    
   tag_t sphere_tag;
   double center[3]={0,  0,0};
   char sphere_diam[256];
   sphere_diam[0]='\0';
   sprintf(sphere_diam,"%f",84.8*2);
  
   UF_MODL_create_sphere1(UF_NULLSIGN,center,sphere_diam,[$sphere_tag)]
  
//============================[2] 2 Trim of sphere====================    
  
  tag_t dplane1;
  double sphere_radius=atof(sphere_diam)/2;
  double dplane1_origin[3];  
  dplane1_origin[0]=0;
  dplane1_origin[1]=0;
  dplane1_origin[2]=-80;
  double dplane1_dir[3]={0,0,1};
  UF_MODL_create_fixed_dplane(dplane1_origin,          dplane1_dir,[$dplane1)]
  
  tag_t dplane2;
  double dplane2_origin[3];  
  dplane2_origin[0]=0;
  dplane2_origin[1]=0;
  dplane2_origin[2]=-60;
  double dplane2_dir[3]={0,0,1};
  UF_MODL_create_fixed_dplane (dplane2_origin,dplane2_dir,[$dlane2)]
  int direction_flag=0;
  tag_t trim_left,trim_right;
  
  int ret=UF_MODL_trim_body(sphere_tag,
        dplane1,
        direction_flag,
        [$trim_left)]
  char test[256];
  sprintf(test,"%d",ret);
  uc1601(test,1);
  //从结果显示 ret=690025
