Remove IFC Entity Node


Recommended Posts

Hi Marionette geniuses!


I wonder if there's an opposite node for


 or a way to workaround to untick/remove IFC entities that were previously attached to objects.


Data Manager has been really helpful attach/manage new IFC data, but when I tried to remove any unwanted entity/data in Data Manager, they still remain in the Data tab in OIP. Only gave me the option to manually untick them in the OIP if this makes sense. I was hoping it can automatically unactivate removed entities...Data Manager is still under developing from what i read, hopefully this will get improved!


I've checked the collection of various nodes shared by AlanW and tried searching across the forum, but got no luck. If it already exists, could you redirect me to the post please?


Thanks in advance!

Hi @Gregi !


Thank you for creating this node! I gave it a test. It works perfectly to delete ALL IFC data attached to any objects.


It's good to have this node too, but maybe I mis-interpreted what I'm looking for here...Each object got IFC data attached shows this nest of info/data below:



The node you created ended up removing the entire IFC Data Set (tbh, the naming system is so confusing🤦‍♂️. The IFC Data Set and the first line IFC Entity (Property Set) both called the same...? not sure if I got it correct here)


I'm looking for a node to remove or untick only 'ONE line' of IFC Entity/ Property Set (equivalent to a record? For example, to untick the line 'Classification' with all other still remain the same) Something like the opposite of the 'Set IFC Property' node maybe...? I guess the sIFCPropValue part would be redundant.




Again, thanks for any help in advance!
