Clash detection pipe insulation without IfcSystem

KaBa

Hello,

I noticed that the IfcSystem for the Insulation of pipes/ducts is not stated in Ifc4 but is in Ifc2x3.

Unfortunatley the clash detection can’t ignore “in the same system” clashes any more like this.
Because of the way Revit creates its Insulation there is always a bit of overlap in some components.
And even if the pipes and fittings are connected/in the same system I get errors like the ones in the picture below.

Is there a possibility without excluding the Insulation from the clash detection all together but still get clashes between Insulations of different systems?

Do you see any relation from insulation to the system? (see relation tab in Info view)

KaBa

No there is no relation to a system. But I neither see it in the Ifc 2x3 verion nor the ifc 4 version, but somehow the System has a value in the 2x3 Version. (See first Picture in first post)

I see the belag is related to rohr. Is the rohr related to the system?

KaBa

Yes it is. I also tried to defined the rule through the relationship but failed because I could not tell the rule to ignore the clash when the backwards relationship of the covering has a pipe and tha pipe has the same system as the covering of the pipe it is clashing with. I could only tell it to exclude the clash when the backwards relationship of the covering has a pipe and that pipe is part of a system. But then, that would just exclude the covering alltogether.

Is there possibility get sample models ifc4 and ifc2x3 to [email protected]?
The system could be found using Covering -> Pipe <- System relation chain. Looks like simple to fix.

This is solved in the latest release: https://society.solibri.com/topic/3487/solibri-25-12-0-has-been-released/
