during some tests on around 2000 ifc files I stumpled above the following. Around 250 files uses the same Project ID 344O7vICcwH8qAEnwJDjSU . But they are around 80 different projects from various different architects. Some files are new, some files are around 5 years old. All of them where exported by ArchiCAD.
The famous Schependomlaan has it too. https://github.com/buildingSMART/Sample-Test-Files/blob/master/IFC%202x3/Schependomlaan/Design%20model%20IFC/IFC%20Schependomlaan.ifc
#56= IFCPROJECT('344O7vICcwH8qAEnwJDjSU',#25, '10 Appartementen Schependomlaan',$,$,$,$,(#53,#197),#42);
Has someone noticed similar problems.
This should not happen IMHO. Would one of you guys out there correct me if I am wrong. I thought a uuid is unique for a project.
