UF_MODL_create_thru_curves1
Defined in: uf_modl_freeform.h
int UF_MODL_create_thru_curves1(UF_STRING_p_t s_section, UF_STRING_p_t s_spine, int * patch, int * alignment, double value [ 6 ] , int * vdegree, int * vstatus, int simple, int * body_type, UF_FEATURE_SIGN boolean, tag_t target_body, double tols [ 3 ] , int c_num [ 2 ] , tag_t * c_face_id [ 2 ] , int c_flag [ 2 ] , int c_dir, tag_t * body_obj_id )
overview 概述
Creates a feature through a collection of curves in one direction. This function behaves like UF_MODL_create_thru_curves with an extra input for passing in the target body for the boolean operation.
If body_type is solid (1) and the sign of the operation to be performed is not create, then the target body is required.
The following restrictions apply:
- The first segment curve of each primary/cross/spine is a starting curve.
- If single patch, then vdegree = 0, vclose = 0 (open.) The output of this function is the object identifier associated to the feature.
- If alignment is set to Spline Points, the input sections must all be single B-curves with the same number of defining points.
通过一个方向的曲线集合创建一个特性。这个函数的行为类似于 UF _ MODL _ create _ thru _ Curve，它有一个额外的输入，用于传递布尔操作的目标主体。如果 body _ type 是实体(1) ，并且要执行的操作的符号不是 create，则需要目标 body。以下限制适用: 1。每个主要/交叉/脊柱的第一段曲线是起始曲线。2.如果是单个补丁，那么 vdec = 0，vclose = 0(open.)这个函数的输出是与特性关联的对象标识符。3.如果对齐设置为样条点，则输入部分必须是具有相同数量定义点的单条 B 曲线。

parameters 参数
| UF_STRING_p_t | s_section | Input | Pointer to the section list structure. When simple option is 2, then the user supplied template string must be added as the last item of this section string structure, but the number of section strings will not be increased. For example, to create a feature using 3 section strings and a user defined template (simple option = 2), num would be 3, but string and dir would have 4 elements, string[3] would be the number of segment curves for the user defined template, and dir[3] would be the direction for the user defined template. The tags for the user defined template would be added onto the end of the id array. int num Total number of section strings (min=2, max=150) int string[ ] Total number of segment curves/ sketch identifier of each section string (min=1, max =402) int dir[ ] Direction of each section string 1 = Start to end -1 = End to start tag_t id[ ] Identifier of section curve or the section builder object tags, but not both 指向节列表结构的指针。如果 simple 选项为2，则必须添加用户提供的模板字符串作为此节字符串结构的最后一项，但是节字符串的数量不会增加。例如，要创建一个特性，使用3节字符串和一个用户定义的模板(简单选项 = 2) ，num 将是3，但 string 和 dir 将有4个元素，string [3]将是用户定义模板的段曲线数，dir [3]将是用户定义模板的方向。用户定义模板的标记将添加到 id 数组的末尾。每节字符串的方向1 = 开始到结束 -1 = 结束到开始标记 _ t id []分段曲线或分段构建器对象标记的标识符，但不能两者兼有 |
| UF_STRING_p_t | s_spine | Input | Pointer to the spine list structure (for alignment = 5). int num Total number of spine string (min=0, max=1) int string[ ] Total number of segment curves/ sketch identifier of each spine string (min=1, max=402) int dir[ ] Direction of each spine string 1 = Start to end -1 = End to start tag_t id[ ] Identifier of spine curve or the section builder object tags, but not both 指向脊柱列表结构的指针(用于对齐 = 5)。每个脊柱字符串的方向1 = 开始到结束 -1 = 结束到开始 tag _ t id []脊柱曲线或剖面构建器对象标记的标识符，但不能两者兼有 |
