标题: 对于一个直接在UG中新建的拉伸特征，到底怎样才能获得其参数？
为什么我写的代码，对UF_MODL_create_extruded创建的特征有效，对直接在UG中新建的拉伸特征无效？

我遍历了部件中的每一个对象，对每一个对象都调用了UF_MODL_ask_extrusion，可见不是TAG传递错误的问题，那为什么还是无效？
难道UF_MODL_ask_extrusion只对UF_MODL_create_extruded创建的特征有效麽？

下面是我写的代码：
#include <uf.h>
#include <uf_exit.h>
#include <uf_ui.h>
#include <uf_part.h>
#include <uf_obj.h>
#include <uf_modl.h>
#include <stdlib.h>
#include <stdio.h>
#include <uf_curve.h>
#include <math.h>
#include <string.h>
#include <uf_csys.h>
#include <uf_mtx.h>

#if ! defined ( __hp9000s800 ) && ! defined ( __sgi ) && ! defined ( __sun )

using std::cerr;
#else
# include <strstream.h>

#endif
#include "UF_MODL_ask_extrusion_EX.h"

line_coords.start_point[0]=start_x;

UF_CURVE_create_line(p_line_coords,&line_tag);
return(line_tag);

  //i=ask_extruded(object_tag);

  num++;
  UF_MODL_ask_feat_name(object_tag,&feature_type);
  error=UF_MODL_ask_extrusion(object_tag, &n_objects, &p_object,

  fprintf(fp,"\n对象%d的id为：%u,其类型为：%s\n错误号为：%d\n",

}while(object_tag!=NULL_TAG);

}

extern "C" DllExport void ufusr( char *parm, int *returnCode, int rlen )

      /* TODO: Add your application code here */
      /* Terminate the API environment */
      errorCode = UF_terminate();
}
/* Print out any error messages */
PrintErrorMessage( errorCode );
}

extern "C" int ufusr_ask_unload( void )
{
return( UF_UNLOAD_IMMEDIATELY );
}
/* PrintErrorMessage
**
**    Prints error messages to standard error and the Unigraphics status
**    line. */
static void PrintErrorMessage( int errorCode )
{
if ( 0 != errorCode )
{
      /* Retrieve the associated error message */
      char message[133];
      UF_get_fail_message( errorCode, message );
      /* Print out the message */
      UF_UI_set_status( message );
      // Construct a buffer to hold the text.
      ostrstream error_message;
      // Initialize the buffer with the required text.
      error_message << endl
                  << "Error:" << endl
                  << message
                  << endl << endl << ends;
   // Write the message to standard error
      cerr << error_message.str();
}
}
打印错误号error的值总是非0，一般是580001和875004。

编译、链接、调用DLL都没有错
就是完成不了功能
