Thanks about your reactivity 🤗 but I unfortunately do not make the same observation ; Hence this post.
I've also found that decomposition of elements during ifc export seems to be handled better with AC26. However, this decomposition of the elements seems to modify the management of the classification of the elements. Even preventing the decomposition of elements during IFC export, the elements do not include their classification.
It is about a AC25 project migrated to AC26. No matter with AC25 with same ifc export parameters.
I have tested again with an empty project with the AC26 basic TPL.
I began by erasing the classification 2.0 to input UNIFORMAT II (E1557-97).
After doing the type matching for ifc export, I tried again to export a simple classified wall (B2010)
When reading the IFC file, the only element of my model corresponds to the ifcwall type but its uniformat class does not seem to be exported. 😕
I follow the same steps with AC25 and classifications are well exported.
