A colleague has uploaded a series of IFC files into a project (in the same folder), but I cannot load a couple of them. They show up as downloaded files, and up to date, but when I try to see them, the filename turns red in the Model Tree, and nothing shows up. In the online viewer, all files work without problems, but in the Desktop version those two cannot be loaded. I am using Trimble Connect version 18.104.22.168.
What can be the problem?
