【求助】ugopen如何选择一条线

yangdan

使用如下方式,可以选择面  
  UF_UI_selection_options_t opts;
  UF_UI_mask_t mask;
  int response;
  tag_t object, view;
  opts.other_options=0;
  opts.reserved=NULL;
  opts.num_mask_triples=1;
  opts.mask_triples=[$mask]
  
  opts.mask_triples->object_type=UF_face_type;
  
  opts.mask_triples->object_subtype=UF_all_subtype;
opts.mask_triples->solid_type=UF_UI_SEL_FEATURE_ANY_FACE;
  
    opts.scope=UF_UI_SEL_SCOPE_ANY_IN_ASSEMBLY;
int irc=UF_UI_select_single(message, [$opts, &response, &object, cursor, &view)]
  
使用同样的方法,将opts.mask_triples->object_type=UF_face_type;
改为opts.mask_triples->object_type=UF_line_type;
  
来选择线,就不行.请问,改如何才能选到线?
