IFC export - ID (name) of composite not attached to its skins

[Johan Stinckens]

I've exported a small sample project to IFC for use in Solibri (Information Takeoff).

Every composite object (walls, slabs) has the ID (Name) attached to it.

When selecting the seperate skins the Name field holds the Material information.

How do I provide the Name field for the skin with the same ID (Name) as the composite it belongs to?!

The information should be there as the skin is a decompose element of the composite.

Hello ,

Do you have a solution for this problem ? 

I have the same !

Hi sma2bim,

I have recently done this using the new component-level type mapping in Archicad 26.

https://help.graphisoft.com/AC/26/INT/index.htm?rhcsh=1&rhnewwnd=0&rhmapid=#t=_AC26_Help%2F005_NewFe...

For IfcWall, IfcSlab, IfcBeam, IfcColumn and IfcStair I added a new IFC Property Component_ID defined as IfcLabel.

I created a new component based rule and added content to map the IfcLabel to the Element_ID of the component.

The IFC export will now contain the Element_ID of the component for the decomposed parts.

In Solibri the wall shows the Element_ID under Identification - Name

When selecting a decomposed part of the component the Element_ID will be shown in AtCo_IFC-Properties as the value for property Component_ID

So now you can easily generate ITO's for a specific building material with relation to the component it is part of.

I hope this helps!

If it does please mark this post as a solution (accept as a solution).

Kind Regards,

Thank you !!!
