Is it loaded, yet?
Theoretically, the limit is what your machine can handle. A 332 MB IFC textfile will result in a SketchUp file of approximate 4-6 GB, if not more…
All IFC objects are considered components, regardless they have the same geometry.
All component axes have the same (origin) outside the component itself, resulting in very slow performance. (This and the deep nesting of the geometry components itself)
On top of it, SketchUp generates thumbnails (for use in the component browser) for each and every component. (consider each component being a little SketchUp-file, opening 100.000+ files takes along time)
Try to extract what you essentially need for the purpose of your model.
