I am not sure what Revit does when using the Reload From option with a IFC link.
But we are having trouble with IFC models (this one from Tekla) beeing empty when using Reload From.
I tried to replicated this behavior by linking an IFC (A). Reloading this file with a new IFC (B).
Then tried to Reload From the original IFC file (A) and it will be empty.
I don't think this will happen often but a collegue of mine had to insert a new IFC link instead of using Reload From.
Because of that, he lost all of the Graphic Overrides.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
We have a similar item in our backlog and we'll be taking a look. In the meantime, you can probably fix the behavior by deleting the .ifc.RVT cached file - that will cause a full reload, and probably have the behavior you expect. Let us know if that solves the problem (as a workaround).

Thank's. I'll forward your suggestion to my collegue.
