Automatic Generating 2D Drawing Based on 3D Feature Design Model
-
摘要: 主要研究了基于参数化特征造型系统("金银花"系统)中二维工程图中的视图布局及图形处理的基本原理及实现方法,重点介绍标准视图和剖视图的生成原理.与传统的二维绘图系统不同,本文的一个特点是由三维模型自动生成二维工程图的视图布局及尺寸标注,实现三维模型与二维图形的双向关联,既修改二维图形,三维模型也会随之改变,反之亦然.Abstract: The basic principle and implementing method was mainly discussed of automatically generating 2D drawing based on parametrical feature modelling system (LONICERA system ). The emphasis is introducing the theorem of creating projection view and cross-sectional view. Different to traditional 2D drafting system, this method can automatically generate 2D drawing from 3D model. The generated 2D drawing is correlated with the 3D model. When modifying the 3D model, the 2D drawing will also be changed. And vice versa.
