Hello, I'm attempting to export an .IFC file from Revit where only the Structural Core layers for my Walls, Floors and Roofs come through - No Finish Layers (Coverings). So far, I have attempted to manipulate the IFC Export Options by using the "Not Exported" value for IFC Class / Type Name on the Finish 1, Finish 2, Membrane and Substrate sub-layers. I am currently using the BIM Vision viewer to validate the export results and it still seems to be producing the overall mass of the wall with sub-layer information. Is what I'm trying to accomplish do-able and if so, what is the best approach for doing so? Thank You!
Working in Revit 2019 at present.
