Hi, I am exporting IFC from Revit and trying to group the parameters (include the built-in and user-added). I used the attached TXT property mapping file and ticked the option in the image.
But I found that in the exported IFC model, some properties defined in the TXT file are exported but some are not. For example, only the "Absorptance" property is exported although I included other properties in the "Analytical" group in the TXT mapping file. Has anyone encountered such an issue? The Revit model and TXT mapping file are attached. Thanks!
