NX二次开发UF_MODL_create_trimmed_sheet 函数介绍

UF_MODL_create_trimmed_sheet

Defined in: uf_modl_freeform.h 
int UF_MODL_create_trimmed_sheet(tag_t sheet_body_tag, int bounding_object_count, tag_t * bounding_objects, UF_MODL_vector_p_t projection_method, int key_pt, int point_count, double point_coords [ ] , double tolerance, int * gap_point_count, double * * gap_points, tag_t * feature_obj_eid )

overview 概述

Modifies the input sheet body to the specified boundary and regional conditions. The boundary conditions (faces, planes, edges, and curves) are used to divide the input sheet body into regions by imprinting new edges on the input sheet body. The regional conditions are employed to classify the discarded and retained regions of the input sheet body. The output sheet body is the retained region(s) of the input sheet body.

将输入工作表正文修改为指定的边界和区域条件。利用边界条件(面、平面、边和曲线) ，通过在输入板体上印刷新的边，将输入板体划分为不同的区域。利用区域条件对输入表体的丢弃区域和保留区域进行分类。输出工作表主体是输入工作表主体的保留区域。
