附录E示例-UT_Alignment_12d_11

示例概述

垂直几何图形（VG）在水平几何图形（HG）之后开始并在其之前结束的示例

与两个左弧之间半径减小的部分回旋线和垂直几何体对齐

起始链长度为0。

只有语义定义，没有ifc几何

意图

IFC 4x3 RC2此场景有一个简单的对齐方式，包括：水平几何体：左弧、半径递减的部分回旋线、左弧垂直几何体：垂直几何体在HG之后开始，在HG结束之前停止

在ifc文件中，有路线的航海定义，但没有ifc几何图形。

 

Ifc文件由12d模型生成-2021 1月4日

 

先决条件

此场景基于场景UT_Alignment_12d_9

 

所容纳之物

本方案涵盖其他概念和/或IFC实体：

 

垂直几何结构在HG之后开始，在HG结束之前停止

 

支持文件

以下文件对应于此场景：

 

Filename	Description
UT_Alignment_12d_11.ifc	the exported content as an IFC file
UT_Alignment_12d_11.png	plan view and section view of the alignment, and the segment parameters (with Civil radius)
