Delete geometry from model in place

Hi,

I’m doing a project where I get an IFC-fil with a lot of ducts and I’m trying to make the ducts into Revit geometry. I have found a plugin for this purpose, but it does not Work properly because the geometry of the ducts is too high. What I need to do to do is to delete the center circle of the extrusion and then it works. is there a way to use dynamo to delete the center circle of the extrusion on all the IFC ducts?
