NX二次开发UF_MODL_create_thru_curves 函数介绍

UF_MODL_create_thru_curves

Defined in: uf_modl_freeform.h 
int UF_MODL_create_thru_curves(UF_STRING_p_t s_section, UF_STRING_p_t s_spine, int * patch, int * alignment, double value [ 6 ] , int * vdegree, int * vstatus, int * body_type, UF_FEATURE_SIGN boolean, double tol [ 3 ] , tag_t c_face_id [ 2 ] , int c_flag [ 2 ] , tag_t * body_obj_id )

overview 概述

Creates a feature through a collection of curves in one direction. The following restrictions apply:

1. The first segment curve of each primary/cross/spine is a starting curve.
2. If single patch, then vdegree = 0, vclose = 0 (open.) The output of this function is the object identifier associated to the feature.
3. 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。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。
