It is possible to preview IFC files in the documents section.

If you click on revisions you will also be able to load this preview in the 3D viewer.
This is useful if your file has an error with uploading and you want to preview it to be able to look at it.

Keep in mind that less information is processed in this view:

GUID's, properties and materials will not be visible in the inspect section.
It will therefore also not be possible to use property libraries with these previews.

It is also not possible to play back views in issues made with these previews

Objects can also not be attached to issues.
