ifc4x3  附录E示例-Georeference_Tiny_Survey_1

示例概述

意图

IFC 4x3 RC1测量字符串和点及其属性集是项目初始数据的基础，用于任何线性项目的放样，并用于机器控制。因此，如何在ifc 4x3中输出这些数据至关重要。

此方案包含一个名为“RD ET”的字符串和一个名“SF LE”的点的调查，以及一个用户定义的属性集“调查”，其中一个文本属性名为“point Id”，值为“3”。

地图投影MGA94 56区的坐标为东距、北距和AHD。IfcProjectedCRS中规定了水平和垂直基准。

ifc文件由12d Model编写。

先决条件

此方案基于以下其他方案：-无

内容

该方案涵盖以下概念和/或IFC实体：

• ifcProjectedCRS
• ifcMapConversion
• ifcPropertySet
• ifcPropertySingleValue

支持文件
