1、NX二次开发习题及源码1、创建NXhello界面代码:#include /包含UF_initialize()和UF_terminate()函数原型的头文件#include /包含uc1601()函数原型的头文件extern void ufusr(char *param, int *retcode, int param_len) if (UF_initialize()!=0)/获取NX openapi的执行权限 return; uc1601(Hello NX,1);/弹出消息窗口,显示“Hello NX” UF_terminate();/释放NX OPEN API的执行权限 运行结果截图:2、创
2、建一个模型,并在信息窗口显示模型的tag值。代码:#include #include #include #include #include #include static void do_ugopen_api(void) typedef unsigned int tag_t; UF_FEATURE_SIGN sign = UF_NULLSIGN;/无布尔运算 double cyl_orig3 = 0,0,0;/圆柱的圆心坐标 char *cyl_height=100; char *cyl_diam=40; double direction3=0,0,1;/延Z轴正方向 tag_t obj=NU
3、LL_TAG; UF_MODL_create_cyl1(sign, cyl_orig,cyl_height,cyl_diam,direction, &obj); UF_UI_open_listing_window(); /显示信息框:tag /*Returns the tag of the current display part. In a non-assembly part, this is the same as the work part. If there currently isnt a displayed part, a NULL_TAG is returned. */ obj=
4、UF_PART_ask_display_part(); if(obj = NULL_TAG) /没有部件的时候显示的信息提示框 uc1601 ( 当前没有任何文件可供操作!,1); else char s10; sprintf(s, %d,obj); /sprinf()功能:把格式化的数据写入某个字符串 UF_UI_write_listing_window(s); return; extern void ufusr( char *param, int *retcode, int rlen )/提供入口点 if(UF_initialize()!=0) return; do_ugopen_api
5、(); UF_terminate(); return;extern int ufusr_ask_unload(void) return(UF_UNLOAD_IMMEDIATELY);运行结果截图:(1)无部件时的输出(2)有部件时的输出结果3、open part 用户入口实例创建open part user exit在用户点击“open”时创建新部件,在其中创建sphere详细说明user exit设置文件过程代码如下:#include #include #include #include #include #include #include #define UF_CALL(X) (repor
6、t( _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
7、_api(void) UF_FEATURE_SIGN sign = UF_NULLSIGN; tag_t part=null_tag;/如果没有赋值的话,直接就是tag_t part,当你执行.dll文件时,就直接跑到建模环境了,没有信息提示框。当然你可以多申明几个tag_t char part_name13 = F:long.prt;/设置part名字以及存储路径 double center 3 =0,0,0;/球心坐标 char * diam=100; int units =1; uc1601(创建直径为100的球,1); UF_PART_new (part_name, units, &p
8、art);/在当前的会话框中创建新的part,并把其作为工作部件 /试比较下面两个函数 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_un
9、load(void) return (UF_UNLOAD_IMMEDIATELY);运行结果截图:4、创建一个block,并指定某一特定面高亮显示。代码如下图:#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,
10、 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 u
11、nits=2;/此行代码的赋值,经过调试,貌似只有1和2可以,它们的区别就是生成模型的默认大小不同,可以自己调调看。 char part_name13=F:long.part;/此段代码有点小重要,注意一定要保证完整性,不完整的话,估计会出现好多问题,绕好多路。 uc1601(创建一个正方体,并指定下表面高亮显示,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,&
12、blk_feat); uf_list_p_t face_list;/链表 UF_MODL_create_list(&face_list);/创建链表 UF_MODL_ask_feat_faces(blk_feat,&face_list);/获取实体的个表面特征,并放入链表中 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);/从链表中取出对象 int type; double point 20 ; double
13、 dir 20 ; double box 6; double radius; double rad_data; int norm_dir; UF_MODL_ask_face_data(obj,&type,point,dir,box,&radius,&rad_data,&norm_dir);/这个函数非常重要,可以说是本段代码中最核心的部分。 if(dir0=0&dir1=0&dir2=-1)/确定高亮显示的那个面的法向量 UF_DISP_set_highlight(obj,1); /UF_OBJ_set_color(obj, 186); break; /*ARGSUSED*/extern vo
14、id 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);运行结果截图:注:和高亮显示还有一个类似的设置,就是给实体上色,所用到的函数是:UF_OBJ_set_color(obj, 186);上面的这个函数是把对象显示成红色,如下图:“186”是红色的代号。这些数字可以在UG交互模式下的
15、对象显示里查到,如下图:5、用遍历的形式输出当前part所有面的tag至listing window代码如下:#include #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,
16、 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; double center 3 = 0,0,0; char * edge_len 3 =100,100,100; tag_t blk_feat =null_tag; char * part_name=F:
17、long; int units=1; tag_t part =NULL_TAG; uc1601(创建一个block,并显示每个面的tag,1); UF_PART_new(part_name,units,&part);/在当前会话窗口中创建一个part,并使其成为工作部件 UF_CALL(UF_MODL_create_block1(sign,center,edge_len, &blk_feat); if(blk_feat = NULL_TAG) uc1601 ( 当前没有任何文件可供操作!,1); else int type=70; int subtype=2; tag_t obj=null_t
18、ag; tag_t display_part=UF_PART_ask_display_part(); UF_OBJ_cycle_objs_in_part(display_part,70,&obj); while(obj!=null_tag) UF_OBJ_ask_type_and_subtype(obj,&type,&subtype);/返回一个被标记的对象的对象类型和子类型 UF_OBJ_cycle_objs_in_part (display_part,UF_solid_type,&obj);/查询遍历对象 if(subtype= UF_solid_face_subtype) char s5
19、0; sprintf(s, %d, obj); UF_CALL(UF_UI_open_listing_window(); UF_CALL(UF_UI_write_listing_window(s); UF_CALL(UF_UI_write_listing_window(n); 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_U
20、NLOAD_IMMEDIATELY);运行结果截屏:6、遍历当前part中所有features,输出其类型至listing window,UF_MODL_ask_feat_type()代码如下:#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, l
21、ine %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) char * part_name=F:NX; UF_FEATURE_SIGN sign = UF_NULLSIGN; tag_t part=null_tag; double center 3 =0,0,0; char * di
22、am=100; int units =1; uc1601(创建直径为100的球,并显示其实体特征。,1); UF_PART_new (part_name, units, &part);/在当前的会话框中创建新的part,并把其作为工作部件 UF_MODL_create_sphere1(sign,center,diam, &part); int count = 0; char* solid_feature; tag_t found = NULL_TAG; tag_t display_part = UF_PART_ask_display_part(); UF_UI_open_listing_win
23、dow(); UF_OBJ_cycle_objs_in_part(display_part,UF_feature_type,&found); while( found != NULL_TAG ) count+; UF_CALL(UF_MODL_ask_feat_type(found,&solid_feature);/获取输入的特征的类型 UF_CALL(UF_UI_write_listing_window(feature:); UF_CALL(UF_UI_write_listing_window(solid_feature); UF_CALL(UF_UI_write_listing_windo
24、w(n); UF_CALL(UF_OBJ_cycle_objs_in_part(display_part,UF_feature_type,&found); 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);运行结果截屏:6、创建人机交互界面新建圆柱体,并可以随意选
25、择原点和矢量方向。代码如下:#include #include #include #include #include #include #include #include #include #include #include #include cylinder.h#define CHANGE_CB_COUNT ( 3 + 1 ) /* Add 1 for the terminator */ tag_t blk_tag= null_tag; double blk_orig = 0,0,0; double direction 3 ; char * part_name=F:long; int uni
26、ts=1;static UF_STYLER_callback_info_t CHANGE_cbsCHANGE_CB_COUNT = UF_STYLER_DIALOG_INDEX, UF_STYLER_APPLY_CB , 0, CHANGE_apply_cb, CHANGE_ACTION_2 , UF_STYLER_ACTIVATE_CB , 1, CHANGE_action_2_act_cb, CHANGE_ACTION_3 , UF_STYLER_ACTIVATE_CB , 1, CHANGE_action_3_act_cb, UF_STYLER_NULL_OBJECT, UF_STYLE
27、R_NO_CB, 0, 0 ;static UF_MB_styler_actions_t actions = cylinder.dlg, NULL, CHANGE_cbs, UF_MB_STYLER_IS_NOT_TOP , NULL, NULL, NULL, 0 /* This is a NULL terminated list */;static int init_proc(UF_UI_selection_p_t select,void *user_data);extern void ufusr (char *param, int *retcode, int rlen) uc1601(创建一个圆柱,并指明原点和矢量,1); UF_PART_new(part_name,units,&blk_tag); int response = 0; int error_code = 0; if ( ( UF_initialize() ) != 0 ) return;
