Upgrade Ifc2x3 to IFC4
I am trying to upgrade IFC2x3 files to IFC4, but using IfcPatch to "migrate"/upgrade throws the following error for most of my .ifc files. I actually only need the geometry, but I do need IFC4 in order to visualize the scheduling. I dont need the migrated .ifc files afterwards either, so it doesnt matter to me if the files have errors in them as long as I can use the 4D/5D BlenderBIM functionality for visualization, at least as a first step.
Does anyone have any tips for getting IFC4 geometry from IFC2x3 files, or how to ignore all errors when using IfcPatch Migrate, or if I need to write a script to process the geometry only myself etc?
See the attached error message (if of interest):
