IFC export problems

When exporting to IFC I often get GUID’s with a value of ‘0000000000000000000000’

This seems to happen with groups, component instances seem to get a decent GUID.

Anyone else experiencing this?

The problem seems to have disappeared by itself, same SU version, I don’t understand what has changed :confused:.
But great that it seems to work fine now :smiley:

if I may suggest, it looks like su file that you export to other programs or other files that you import into the SU does not correspond or no fil types of import or export on both sides (program). so before you clicking exports from one program to another should be carefully first if both sides accept each type of file that is imported or exported.
hope it is useful
