zzz你好，假如有如下程序，对一打开的prt文件做如下操作；
#include <stdio.h>
#include <uf.h>
#include <uf_curve.h>
#include <uf_modl.h>
#include <uf_part.h>
#include <uf_so.h>

#define UF_CALL(X) (report( __FILE__, __LINE__, #X, (X)))

static int report (char *file, int line, char *call, int irc)
{
   if (irc)
   {
      char messg[133];
      printf("%s, line %d, %s\n", file, line, call);
      UF_get_fail_message (irc, messg);

      printf("  returned a %d\n", irc);
      printf("  returned error %d, %s\n", irc, messg);
   }
   return (irc);
}

static void do_ugopen_api (void)
{
   double plane_data[9] = {100.0,0.0,50.0, 100.0,0.0,49.0, 100.0,1.0,50.0};
   double vect[3] = {250.0, 0.0, 0.0};
   double vect2[3] = {250.0, 50.0, 0.0};
   int curr_part,num_parts,count_1;

   tag_t  part_tag, block_tag, plane_tag;

   tag_t  objects[1], planes[1];
   tag_t  section_curves_feature, *section_curves;

   tag_t  feature;
      const logical flip = TRUE;

   int num_section_curves, type;



   UF_CURVE_section_general_data_t  general_data;

   char  *part_name = "section_curves";

   char  *edge_lens[3] = {"300.0","25.0","150.0"};

在此应获得block_tag的值（也就是打开的part中的值），我不知如何处理，请大侠帮助解决？

int type, subtype;

part_tag = UF_PART_ask_display_part();
block_tag = NULL_TAG;
UF_OBJ_cycle_objs_in_part(part_tag, UF_solid_type, [$block_tag)]
while(block_tag)
{
   UF_OBJ_ask_type_and_subtype(block_tag, [$type, &subtype)]
   if(subtype == UF_solid_body_subtype)
   {
            break;
   }
   UF_OBJ_cycle_objs_in_part(part_tag, UF_solid_type, [$block_tag)]
} objects[0] = block_tag;

   FTN(uf5374) (&plane_data[0], &plane_data[3], &plane_data[6],
                  [$plane_tag)]


planes[0] = plane_tag;

   general_data.associate    = 1;
   general_data.objects    = objects;
   general_data.num_objects = 1;
   general_data.grouping    = 0;
   general_data.join_type    = 0;
   general_data.tolerance    = 0.0254;

   planes_data.planes       = planes;
   planes_data.num_planes    = 1;

UF_CALL (UF_CURVE_section_from_planes (&general_data, &planes_data,
                  [$section_curves_feature))]

   printf (" section curves feature tag is %d\n", section_curves_feature);

parallel_data.base_plane    = plane_tag;
   parallel_data.step_distance  = 3.0;
   parallel_data.start_distance = 0.0;
   parallel_data.end_distance = 10.0;

   UF_CALL (UF_CURVE_section_from_parallel_planes ([$general_data, [$para]]llel_data,
                  [$section_curves_feature))]

   UF_CALL (UF_CURVE_ask_feature_curves (section_curves_feature,
                     [$num_section_curves, §ion_curves))]

   UF_free (section_curves);

}

void ufusr (char *param, int *retcode, int paramLen)
{
   if (!UF_CALL(UF_initialize()))
   {
      do_ugopen_api();
      UF_CALL(UF_terminate());
   }
}

int ufusr_ask_unload(void)
{
   return (UF_UNLOAD_IMMEDIATELY);
}

你用下面的代码没有作出来，那就是你的问题了。我自己前两天才编了，使用良好。
  //include the head files needed.
  tag_t body_tag=NULL_TAG;
  tag_t feat_tag=NULL_TAG;
  tag_t part_tag=NULL_TAG;
  
  //get the tag of the current display part.
  Part_tag=UF_PART_ask_display_part();
  // find the solid body by a feature associated with it.
feat_type=UF_feature_type;

if(feat_tag==NULL_TAG)
{
   uc1601("no feature found",1);
   UF_terminate();
}
UF_MODL_ask_feat_body(feat_tag, [$body_tag)]
