附录E示例-项目设置_1
示例概述
意图
此场景封装了使用正确单元和项目上下文设置的模型。-它将项目单位设置为国际单位制或基于换算的单位。-它包含一个GUID为2DAvEupIz0HQr73cMaawtY的项目“Boileplate”,该项目建立了IFC文件交换的最低限度。-它为几何图形建立了一个几何上下文。
先决条件
此方案基于以下其他方案:-无
所容纳之物
此场景包含以下概念和/或IFC实体:-项目上下文-IfcProject-几何上下文-IfcGeometricRepresentationContext-默认单位分配-IfcUnitAssignment-IfcUnit-IfcSIUnit-IfcConversionBasedUnit-IfcMonetaryUnit-IfcMeasureWithUnit
支持文件
以下文件对应于此场景:
Filename | Description |
---|---|
UT_ModelSetup_1.ifc |
the IFC document |
补充说明
该UT确定了IFC文件中IFC内容的最小值。里面没有产品、几何图形、财产或任何东西。主要目的是为所有UT提供基础,其中将包括样板内容,但未详细解释。
