uc1601(創(chuàng)建直徑為100的球,1);UF_PART_new (part_name, units, &part);/在當前的會話框中創(chuàng)建新的part，并把其作為工作部件/試比較下面兩個函數(shù)UF_MODL_create_sphere(sign,part,center,diam, &part );/UF_MODL_create_sphere1(sign,center,diam, &part);extern void ufusr(char *param, int *retcode, int paramLen) if (!UF_CALL(UF_initialize() do_ugopen_api();UF_CALL(UF_terminate(); extern int ufusr_ask_unload(void)return (UF_UNLOAD_IMMEDIATELY);運行結果截圖：4、創(chuàng)建一個block，并指定某一特定面高亮顯示。代碼如下圖：#include #include #include #include#include#include#include#define UF_CALL(X) (report( _FILE_, _LINE_, #X, (X)static int report( char *file, int line, char *call, int irc)if (irc)char messg133;printf(%s, line %d: %sn, file, line, call);(UF_get_fail_message(irc, messg) ?printf( returned a %dn, irc) :printf( returned error %d: %sn, irc, messg);return(irc);static void do_ugopen_api(void)UF_FEATURE_SIGN sign=UF_NULLSIGN; tag_t obj=null_tag;double center 3=0,0,0 ; char *edge_len3=10,10,10;tag_t blk_feat;int units=2;/此行代碼的賦值，經過調試，貌似只有1和2可以，它們的區(qū)別就是生成模型的默認大小不同，可以自己調調看。char part_name13=F:long.part;/此段代碼有點小重要，注意一定要保證完整性，不完整的話，估計會出現(xiàn)好多問題，繞好多路。uc1601(創(chuàng)建一個正方體，并指定下表面高亮顯示,1);UF_PART_new(part_name,units,&obj);/UF_MODL_create_block(sign,obj,center,edge_len,&blk_feat);UF_MODL_create_block1(sign,center,edge_len,&blk_feat);uf_list_p_t face_list;/鏈表UF_MODL_create_list(&face_list);/創(chuàng)建鏈表UF_MODL_ask_feat_faces(blk_feat,&face_list);/獲取實體的個表面特征，并放入鏈表中int count=0;UF_MODL_ask_list_count(face_list,&count);for(int i=0;icount;i+)UF_MODL_ask_list_item(face_list,i,&obj);/從鏈表中取出對象int type;double point 20 ;
