Hi Community,

I have encountered in a problem when I try to import on a map a IFC File.

In this file there are the most part of the IfcProduct classified as IfcFlowFitting that the type is IfcDistributionElementType. In the same IFC document there are two IfcProduct that are IfcFlowFitting but are classified as IfcPipeFittingType.

In according with the IFC documentation the IfcPipeFittingType is a specialization of the class  IfcDistributionElementType that is viewable here:

BuildingSmart documentation - IfcDistributionElementType 

ArcGis Pro behaves strangely ignoring all the IfcFlowFitting classified as IfcDistributionElementType and on the map the geometry result not visible.

In the image below it's possible to see what is in the IFC File:

But in this second image it's possible to see what ArcGIS Pro show:

As you can you see, ArcGIS Pro show only the two IfcFlowFitting classified as IfcPipeFittingType but the rest is not imported in the scene.

Anyone can help me to solve this issue?

Is this something that was not considered when importing the IFC file?

 

Thanks!

Hello Simone, 

The issue has been resolved on Pro 3.1.

你好DA,

我发现这个问题在3.1pro软件中仍然存在,你能详细说明一下吗?

Hi @EnjingZhang   

Would be possible for you to share some screen capture where you have the issue?

感谢您及时回复我!

这是使用BIMvision查看的IFC2×3格式文件能够准确地看到模型EnjingZhang_1-1695039355362.jpeg

但是,将 IFC 文件导入 ArcGIS pro 以进行地理配准会显示图层为空白

这是添加到 PRO 中用于显示的属性,它的单位是度(deg)

这是文件的属性EnjingZhang_5-1695039910763.png

我想问你为什么从BIM导出的IFC文件在PRO中导入时不显示在场景中,

Hi @EnjingZhang 

Based on the screen captures the issue appears to be a georeference issue and not a data issue. This link will guide you https://learn.arcgis.com/en/projects/geolocate-a-3d-digital-building-model/ through the georeference process.

非常感谢您的回答,我将首先学习地理配准,看看是否可以解决IFC导入Pro无法显示的问题。祝你工作顺利,生活幸福
