Yes, as I am traditionally using import export to add IFC property programmatically, just like the first image
But I found in this dialogue it does not support Chinese, like the situation on the first image, after save/load file
or import ifc xml/export ifc xml they will become garbled text.
However, when I modify them in IFC Manager, like the second image, it does support Chinese and they are preserve even though I save load file. So I wonder if there are any way to programmatically add property in IFC Manager, or other ways which I don't know? Thanks!
