error to export IFC

[Anonymous]

Hi! I have an error when I try to save a file as generic IFC only by layer, and on the report, I have this string of letter and numbers and when I try to find that element in ArchiCAD I cannot find the element.
there is a way to see which object has a wrong geometry?
Thanks

It usually happens when you have 3D compatible elements, like objects which have only 2D but no 3D in it, or when you have 2D selected elements in your plan and you export "selected elements".
To be sure you can use the Find & Select dialog box, and enter as criteria under "All types", the external IFC ID (these number and letters chain you pointed) in every plan view.
